Makati City contains office towers, hotels, hospitals, condominiums, shopping facilities, banks, data centers and mixed-use developments with different occupancy profiles and fire-safety requirements.
A fire alarm system helps detect specified fire-related conditions, notify occupants and personnel, and initiate approved building-system responses. However, it does not prevent every fire, guarantee safe evacuation or replace sprinklers, passive fire protection, emergency planning and trained personnel.
An effective system must be designed for the actual building, installed correctly, coordinated with other life-safety systems, tested as an integrated system and maintained throughout its operating life.
Infinite Systems designs, supplies, installs, integrates and maintains suitable fire alarm and life safety systems for commercial, residential, institutional and industrial properties in Makati and other Philippine locations.
What Is a Fire Alarm System?
A fire alarm system monitors initiating devices such as smoke detectors, heat detectors, manual call points and supervisory inputs.
When the fire alarm control panel receives a valid signal, it processes the programmed logic and activates the applicable outputs. Depending on the approved design, these may include:
- Audible alarms
- Visual notification appliances
- Fire-alarm annunciators
- Emergency voice messages
- Monitoring-station signals
- Door-release interfaces
- Turnstile emergency operation
- Elevator recall interfaces
- Smoke-control or HVAC commands
- Building-management system monitoring
- Other approved life-safety functions
The exact response depends on the building occupancy, fire strategy, approved plans and cause-and-effect sequence.
Not every alarm should produce the same output in every building.
Fire Alarm Systems Do Not Work Alone
A fire alarm system is one part of a broader fire- and life-safety strategy.
Other elements may include:
- Fire-resistant construction
- Compartmentation
- Protected exit routes
- Automatic sprinkler systems
- Standpipes and hose systems
- Fire pumps and water storage
- Smoke-control systems
- Emergency lighting
- Exit signs
- Emergency power
- Fire extinguishers
- Voice evacuation
- Fire command facilities
- Emergency procedures
- Trained building personnel
The fire alarm system may monitor or interface with some of these systems, but it does not replace their independent functions.
For example, ordinary automatic sprinklers generally operate individually in response to sufficient heat at the sprinkler head. They should not be described as being automatically discharged throughout the building by a smoke detector or fire alarm panel.
Conventional and Addressable Fire Alarm Systems
Fire alarm systems are commonly classified as conventional or addressable.
Conventional Fire Alarm Systems
A conventional panel monitors devices arranged into detection zones. When a device operates, the panel identifies the affected zone rather than necessarily identifying the individual device.
Conventional systems may be considered for smaller or less complex applications where the approved design can provide adequate alarm identification and coverage.
Potential advantages include:
- Relatively straightforward architecture
- Familiar maintenance procedures
- Suitability for selected smaller facilities
- Lower complexity for simple applications
Important considerations include:
- Less precise event identification
- More field investigation within an alarmed zone
- Limited expansion compared with some addressable platforms
- More wiring depending on the design
- Restricted integration capabilities on certain systems
Addressable Fire Alarm Systems
An addressable system assigns an identity to each compatible device or module. The panel can indicate which device or interface reported an alarm, supervisory event or fault.
This can support faster investigation and more detailed system monitoring in large or complex buildings.
Potential advantages include:
- Individual device identification
- Detailed event history
- Flexible cause-and-effect programming
- Easier location of some faults
- Support for larger and more complex projects
- Broader integration options on suitable platforms
An addressable system is not automatically compliant or appropriate simply because it is more advanced. The final design must still satisfy the approved fire-safety requirements.
Core Fire Alarm System Components
A complete system may include the following components, depending on the approved design.
Fire Alarm Control Panel
The fire alarm control panel, or FACP, receives signals, applies the programmed logic, supervises system circuits and activates the applicable outputs.
Panel selection should consider:
- Required system capacity
- Number of loops or zones
- Notification circuits
- Standby power
- Networked panels
- Annunciators
- Event history
- Expansion requirements
- Supported detectors and modules
- Integration interfaces
- Manufacturer support
- Testing and maintenance requirements
Smoke Detectors
Smoke detectors are designed to respond to particular smoke conditions. Their suitability and spacing depend on the environment, ceiling configuration, airflow, occupancy and approved design.
A smoke detector may not be appropriate in every location. Dust, steam, cooking aerosols, high airflow or normal industrial processes can contribute to unwanted alarms.
Heat Detectors
Heat detectors respond to specified temperature conditions or rates of temperature increase, depending on the device.
They may be considered in environments where smoke detection is unsuitable, but they should not be described as a universal substitute for smoke detectors. Selection must follow the project’s approved design criteria.
Manual Call Points
Manual call points allow occupants or personnel to initiate an alarm manually.
Their quantity, location, mounting and accessibility must be coordinated with the applicable design and code requirements.
Audible and Visual Notification Appliances
Bells, horns, sounders, speakers and strobes notify occupants of an alarm or emergency condition.
The required device type, sound level, visibility, spacing and circuit arrangement depend on the building and approved design.
Input and Output Modules
Addressable modules may monitor or control other equipment, including:
- Sprinkler supervisory switches
- Waterflow switches
- Fire-pump status
- Door-release circuits
- Elevator interfaces
- Smoke-control equipment
- Fire dampers
- Emergency power status
- Suppression-system panels
- Other approved building-system interfaces
Interfaces should be documented in a cause-and-effect matrix and tested with the responsible trades.
Detection Device Selection
Detector selection should be based on the expected fire signature and normal environmental conditions.
Design considerations include:
- Occupancy type
- Combustible materials
- Ceiling height
- Air movement
- Air-conditioning supply and return locations
- Dust and humidity
- Cooking or steam
- Temperature range
- Outdoor exposure
- Electrical equipment
- Maintenance access
- Risk of physical damage
- Required response
- Possibility of unwanted alarms
Installing more smoke detectors without considering the environment does not necessarily improve safety. Incorrect application can create frequent nuisance alarms, leading users to disregard or improperly disable devices.
A qualified fire-protection professional should establish the final detection strategy.
Fire Alarm Zoning and Alarm Identification
Clear alarm identification helps building personnel locate and investigate an event.
A system may be organized according to:
- Building
- Tower
- Floor
- Fire compartment
- Tenant area
- Parking level
- Plant room
- Data or equipment room
- Elevator lobby
- Stairwell
- Other defined risk areas
The zoning and device descriptions displayed at the panel should correspond with the actual building layout.
Generic labels such as “Device 47” provide less operational value than descriptions such as “Level 12 East Corridor Smoke Detector,” provided the labels remain accurate after renovations.
Cause-and-Effect Programming
A cause-and-effect matrix defines how the system responds to each type of event.
Possible inputs include:
- Smoke-detector alarm
- Heat-detector alarm
- Manual call-point activation
- Sprinkler waterflow
- Valve supervisory condition
- Suppression-system discharge
- Fire-pump status
- Equipment fault
- Emergency control input
Possible outputs include:
- Building-wide notification
- Zoned notification
- Voice evacuation
- Elevator recall signal
- Door release
- Turnstile emergency mode
- Smoke-control command
- Fan shutdown
- Damper command
- BMS monitoring point
- Signal transmission
- Fire command-center indication
The matrix should identify the responsible system and trade for every input and output.
Programming should not be based on assumptions made independently by one contractor. It must reflect the approved fire strategy and coordinated project documentation.
Access-Control Door Integration
Fire alarm systems may interface with selected access-controlled doors where required by the approved design.
Depending on the door, lock and egress arrangement, emergency operation may involve:
- Releasing an electromagnetic lock
- Removing power from selected locking hardware
- Monitoring an emergency-release device
- Preserving free egress from the occupied side
- Maintaining security in an approved direction
- Reporting the door or interface status
- Providing a local manual release
Not every access-controlled door must respond in exactly the same way.
Door operation should be coordinated among the fire alarm, access control, electrical, architectural and door-hardware teams. Final behavior should also reflect the approved plans and applicable authority requirements.
The fire alarm interface must not be used to compensate for unsuitable locking hardware or an inadequate egress design.
Turnstile and Entrance-Control Integration
Turnstiles and speed gates can become obstacles if their emergency behavior is not properly planned.
Depending on the equipment and approved evacuation strategy, an interface may:
- Release tripod arms
- Open swing barriers
- Place speed gates into an emergency mode
- Unlock an adjacent emergency gate
- Provide local guard control
- Report the interface status
A fire alarm signal should not be assumed to make every turnstile safe automatically. The system’s actual mechanical and electrical response must be tested.
An accessible and adequately sized evacuation route should remain available in accordance with the approved design.
Elevator System Interfaces
Fire alarm systems may provide approved signals to the elevator-control system for functions such as recall or status monitoring.
The elevator manufacturer or authorized elevator contractor remains responsible for the elevator’s operation.
Coordination should define:
- Which fire alarm inputs initiate recall
- Primary and alternate recall levels
- Machine-room or control-space detection
- Elevator lobby detection
- Interface voltage and contact requirements
- Signal supervision
- Fire-service operating modes
- Testing responsibilities
- Applicable software or controller requirements
Do not connect unapproved signals directly to elevator equipment.
The final interface should be developed and tested with the elevator contractor and relevant fire-safety professionals.
HVAC and Smoke-Control Integration
A fire alarm system may provide signals to HVAC or smoke-control equipment where required by the approved design.
Potential functions include:
- Air-handling unit shutdown
- Smoke-exhaust activation
- Stair-pressurization commands
- Damper operation
- Fan-status monitoring
- Equipment-fault monitoring
- Smoke-control mode indication
Ordinary comfort air-conditioning and engineered smoke control are not the same.
Smoke-control sequences require coordinated mechanical, electrical, controls and fire-alarm design. The fire alarm contractor should not independently determine fan and damper sequences without the approved mechanical and fire-safety documentation.
Integrated testing should confirm both the command and the resulting equipment status.
Emergency Voice Evacuation and PA/BGM Integration
Large or complex buildings may use emergency voice messages to provide instructions during an incident.
Where approved and properly designed, integration with a PA/BGM and voice evacuation system may provide:
- Emergency override of normal audio
- Zoned evacuation messages
- Alert and evacuation sequences
- Fire command-center paging
- Priority microphone operation
- Pre-recorded instructions
- Supervision of critical circuits
- Backup power
Voice evacuation is more than connecting the fire alarm panel to a normal commercial paging amplifier.
The system should address:
- Speech intelligibility
- Required sound levels
- Loudspeaker coverage
- Circuit supervision
- Message priority
- Emergency power
- Zoning
- Equipment survivability where required
- Manual emergency control
- Testing under realistic ambient-noise conditions
Final message content and evacuation sequences should reflect the approved emergency plan.
Building Management System Integration
A building management system may receive selected fire-alarm information for centralized facility monitoring.
This can include:
- Common alarm
- Common fault
- Supervisory condition
- Panel status
- Selected zone or point information
- Interface-equipment status
The BMS should not be assumed to replace the listed fire alarm control panel, fire command center or required annunciators.
Where permitted, the BMS may display fire-system information, but alarm acknowledgment, reset, silence and control functions should remain within the approved fire alarm architecture unless specifically designed and authorized otherwise.
Integration should also avoid creating network or software dependencies that could compromise fire alarm operation.
Fire Alarm Monitoring and Signal Transmission
Some buildings transmit alarm, supervisory or fault signals to an approved monitoring location.
The arrangement may involve:
- A constantly attended fire command center
- Building security personnel
- A remote monitoring service
- Another approved receiving location
- Redundant communication paths where required
The transmission method, response procedure and responsible personnel must be clearly defined.
Remote notification does not replace onsite notification, emergency procedures or required contact with emergency services.
False Alarms and Unwanted Activations
Frequent unwanted alarms can interrupt operations and reduce occupant confidence.
Possible causes include:
- Incorrect detector application
- Dust from construction or renovation
- Steam or cooking aerosols
- Poor detector placement
- Contaminated devices
- Electrical faults
- Water intrusion
- Inadequate maintenance
- Incorrect programming
- Uncontrolled testing
- Work performed without isolating and restoring affected zones properly
Reducing unwanted alarms may require:
- Reviewing detector type and location
- Improving housekeeping
- Coordinating renovation work
- Cleaning or replacing contaminated devices
- Correcting wiring faults
- Reviewing alarm history
- Adjusting approved programming
- Improving permit-to-work procedures
- Training authorized personnel
Devices should not be disabled permanently merely because they generate repeated alarms. The cause should be investigated and corrected through an approved process.
Renovations and Tenant Fit-Outs
Makati office buildings frequently undergo tenant renovations, floor reconfigurations and changes in occupancy.
These changes can affect:
- Detector spacing
- Ceiling layouts
- Air-conditioning patterns
- Notification coverage
- Fire-alarm zoning
- Door interfaces
- Voice-evacuation speaker coverage
- Occupant load
- Exit arrangements
- Device labels and drawings
Fire alarm devices should not simply be covered, removed or relocated by an interior-fit-out contractor without proper coordination.
Before renovation, the project team should determine:
- Which devices and circuits are affected
- Whether temporary protection is required
- How construction dust will be controlled
- Who may isolate and restore the system
- Whether approved drawings require revision
- What testing is required before turnover
- Whether the building’s cause-and-effect sequence changes
The building’s final drawings and device records should be updated after approved modifications.
Existing-System Upgrades
Replacing an old fire alarm panel does not necessarily mean every existing detector, cable, sounder and interface can be reused.
An upgrade assessment should examine:
- Existing panel condition
- Device compatibility
- Wiring condition
- Circuit topology
- Battery and power-supply condition
- Available spare capacity
- Notification circuits
- Existing interfaces
- False-alarm history
- Obsolete or unsupported components
- Current building layout
- Renovations not reflected in drawings
- Required testing and documentation
Equipment from different manufacturers or product generations may not be interoperable.
Compatibility should be confirmed using the manufacturers’ approved documentation rather than assumed from connector type or voltage alone.
Power Supplies and Standby Batteries
Fire alarm systems require dependable primary and standby power.
The design should address:
- Dedicated power arrangements
- Battery capacity
- Charger capacity
- Panel and remote power-supply loads
- Notification appliance demand
- Voltage drop
- Battery condition
- Environmental temperature
- Expansion allowance
- Monitoring of power faults
Battery capacity should be calculated according to the approved design requirements and actual connected load.
Replacing batteries based only on appearance is insufficient. Batteries should be inspected and tested according to the applicable maintenance procedure and manufacturer guidance.
Fire Alarm Documentation
Complete documentation supports testing, maintenance, renovation and emergency response.
The turnover package may include:
- Approved plans
- Device layouts
- Riser diagrams
- Loop and zone schedules
- Battery calculations
- Voltage-drop calculations
- Cause-and-effect matrix
- Interface diagrams
- Cable and device schedules
- Product data
- Programming records
- Test reports
- As-built drawings
- Operation and maintenance manuals
- Training records
- Warranty documents
- Deficiency and corrective-action records
The final documentation should match the installed system.
Testing and Commissioning
Testing should verify more than whether a detector can activate a sounder.
A commissioning program may include:
- Smoke-detector testing
- Heat-detector testing
- Manual call-point testing
- Waterflow and supervisory input testing
- Alarm notification
- Visual notification
- Voice-message operation
- Panel display and device labels
- Alarm, fault and supervisory reporting
- Open- and short-circuit fault monitoring
- Primary and standby power
- Battery operation
- Networked panel communication
- Door-release interfaces
- Turnstile emergency operation
- Elevator interfaces
- HVAC shutdown
- Smoke-control commands
- Damper operation
- BMS monitoring
- Remote signal transmission
- Event history
- Reset and restoration
- Cause-and-effect sequences
Interface testing should involve the responsible contractors for the connected systems.
Test results, observed deficiencies and corrective actions should be documented before final acceptance.
Preventive Maintenance
Fire alarm systems can deteriorate through contamination, battery aging, wiring faults, environmental exposure, building alterations and equipment obsolescence.
A preventive-maintenance program may include:
- Panel inspection
- Alarm, fault and supervisory testing
- Detector testing and cleaning where appropriate
- Manual call-point testing
- Notification-appliance testing
- Battery inspection and testing
- Power-supply inspection
- Circuit and communication testing
- Interface testing
- Event-history review
- Device-label verification
- Drawing and record updates
- Review of disabled or isolated points
- Replacement of defective or obsolete components
- Coordination of outstanding deficiencies
The required inspection and testing program should reflect the approved system, applicable rules, manufacturer instructions and building procedures.
Maintenance does not automatically guarantee regulatory certification. Identified defects must be corrected, and the responsible owner or administrator must complete any required regulatory process.
Philippine Fire-Safety Regulatory Coordination
Fire alarm and life-safety projects in Makati should be coordinated with the building owner, design professionals, fire-safety practitioners, contractors and the appropriate Bureau of Fire Protection office.
Republic Act No. 9514, the Revised Fire Code of the Philippines of 2008, provides the national legal framework for fire safety. The applicable Revised Implementing Rules and Regulations and other relevant codes, standards and approved plans must also be considered.
Depending on the project stage and scope, regulatory processes may include a Fire Safety Evaluation Clearance, Fire Safety Inspection Certificate or other applicable BFP requirements.
The BFP evaluates plans and conducts inspections within its authority. A supplier or integrator should not promise that equipment installation alone will guarantee approval, certification or issuance of a permit.
Renovations, changes in occupancy and alterations to the original building may require additional review.
Project requirements should be confirmed using the current rules and directly with the relevant authorities.

Frequently Asked Questions
What is the main purpose of a fire alarm system?
A fire alarm system detects specified fire-related conditions, notifies occupants or personnel and initiates approved building-system responses. It does not prevent every fire or replace other required fire-protection measures.
What is the difference between conventional and addressable fire alarms?
A conventional system generally identifies an alarmed zone. An addressable system can identify individual compatible devices or modules. The appropriate choice depends on the building, system complexity and approved requirements.
Are smoke detectors required in every room?
Not necessarily. Detector type and location depend on the occupancy, environment, approved design and applicable requirements. Heat detection or another strategy may be appropriate in some areas.
Does a smoke detector automatically activate the sprinklers?
Ordinary automatic sprinkler heads generally operate individually when exposed to sufficient heat. A smoke detector does not normally cause all sprinklers in a building to discharge.
Can the fire alarm release access-controlled doors?
It can provide approved release signals for selected doors, but the required operation depends on the lock, door hardware, egress design and approved fire-safety strategy.
Can a fire alarm open turnstiles during an emergency?
Compatible turnstiles can be configured for an approved emergency mode. The actual mechanical response, adjacent evacuation route and accessible passage must be tested.
Can the fire alarm control elevators?
The fire alarm system may provide approved input signals to the elevator-control system. The elevator contractor remains responsible for elevator operation and testing.
Can the fire alarm be integrated with the BMS?
Selected alarm, fault, supervisory and equipment-status signals may be displayed by the BMS. The BMS should not replace the required fire alarm control and annunciation equipment.
Is a PA/BGM system automatically suitable for voice evacuation?
No. Emergency voice evacuation requires appropriate equipment, supervision, backup power, coverage, intelligibility, priority control and an approved sequence. A standard paging system may not satisfy those requirements.
How often should a fire alarm system be tested?
The testing frequency and scope depend on the applicable requirements, approved system, manufacturer guidance and building procedures. The owner or administrator should maintain a documented inspection and testing program.
Can an old system be upgraded without replacing all devices?
Possibly, but reuse depends on compatibility, condition, wiring, capacity and approved requirements. Existing components should be assessed before procurement.
Does installing a fire alarm guarantee a Fire Safety Inspection Certificate?
No. Certification depends on the building’s overall compliance, required documentation, inspection results and applicable BFP processes—not on one system alone.
Does Infinite Systems serve fire alarm projects in Makati?
Yes. Infinite Systems can assess, design, supply, install, integrate and maintain suitable fire alarm and life-safety systems for offices, condominiums, commercial properties and other facilities in Makati and surrounding areas.
