Addressable Fire Detection Systems

As SF Fire & Ventilation Systems, our addressable fire alarm systems are advanced, microprocessor-controlled fire detection and alarm solutions designed for precise detection, intelligent monitoring, and reliable fire safety management in complex and large-scale facilities.

System Compatibility

The addressable fire alarm panel is compatible with a wide range of field devices, including:

• Analog addressable smoke detectors
• Heat detectors
• Beam-type smoke detectors
• Flammable gas and carbon monoxide detectors
• Addressable indoor and outdoor manual call points
• Field control modules
• Short-circuit isolators
• Indoor and outdoor audible/visual alarm devices

Loop Capacity and Wiring

• Up to 200 addresses per loop
• Loop length support: up to 2000 meters
• Cable type: 2-core 1.5 mm² fire-resistant cable

Each device (detector, call point, control module) is assigned a unique address.

Key principles:

• Short-circuit isolators are not addressable
• They protect the loop against short-circuit faults
• Devices on the same loop operate independently
• Failure or removal of one device does not affect others

System Architecture and Communication

• No physical interconnection required between loops
• Devices from different loops can participate in automation logic
• System can operate standalone or as part of a distributed network
• Network communication ports enable multi-panel integration
• Prevents total system failure in case of a fault
• Enables centralized monitoring and alarm management from multiple locations

Panel Features

The panel is fully microprocessor-controlled and provides advanced monitoring capabilities:

• LCD display showing all system faults
• Zone-specific fire indicator LEDs
• Backlit alpha-numeric display
• Local audible warning device
• Real-time display of device status (isolated/not isolated, analog value, location, and assigned area name)

Additional Functions

• Optional mini thermal printer support
• System time retained even during total power loss
• Separate day/night operation modes
• Pre-alarm function for early intervention before audible alarms activate
• Continuous monitoring of detector contamination level (“Service Required” warning)
• Continuous supervision of all cables for faults such as open circuit, short circuit, and earth leakage
• Event memory storage up to 500 events
• Software programming and backup via computer interface
• Secure password protection for unauthorized access prevention

Power Supply and Backup

• System operates on 24 V DC
• Powered via a 220 V AC, 50 Hz main supply unit
• Maintenance-free sealed battery backup system
• Automatic switchover during mains failure

Backup performance:

• At least 24 hours standby operation
• Followed by 30 minutes of full alarm and control operation

Addressable Repeater Panel

• Installed in security rooms or control points
• Provides full duplication of main panel functions
• Enables monitoring of all alarms and faults
• Includes zone-specific LEDs, alpha-numeric display, and local audible alarm

Addressable Optical Smoke Detectors

• Sensitive to particles between 0.5 – 10 microns
• Photoelectric light scattering principle
• Transmits analog smoke levels to the panel
• Resistant to environmental effects such as temperature, humidity, and dust
• Plug-in design for easy maintenance
• Detection coverage: up to 100 m²

Addressable Heat Detectors

• Microprocessor-controlled semiconductor sensing element
• Configurable as fixed temperature or rate-of-rise detector
• Adjustable alarm thresholds: 60°C / 77°C / 90°C
• Fast thermal response housing design
• Detection coverage: up to 50 m²

Addressable Combined Smoke + Heat Detectors

• Simultaneous detection of smoke and heat
• Dual-function operation (independent or combined logic)
• RGB LED indicators (green, yellow, red)
• Continuous communication with the control panel
• Detection coverage: up to 100 m²

Addressable Manual Call Points

• Microprocessor-controlled manual alarm devices
• Available in surface-mounted and flush-mounted versions
• Break-glass or resettable types
• Testable without breaking the glass using a test key
• Designed for safe manual activation

Addressable Audible & Visual Devices

• Powered directly via loop wiring
• Available as sounder, beacon, or combined units
• Sound levels:
  • 87 dB (low)
  • 93 dB (medium)
  • 101 dB (high)
• Fully programmable via the panel

Monitoring and Control Modules

• Used for sprinkler systems, alarm inputs, and general fire safety devices
• Support normally open and normally closed contacts
• Microprocessor-controlled modular design
• Expandable system architecture

Control Modules

• Used to activate audible alarm devices
• Programmable continuous or pulsed output operation

SF Fire & Ventilation Systems delivers intelligent addressable fire alarm solutions with high accuracy, continuous system supervision, and maximum reliability, ensuring advanced fire safety for modern infrastructures.
