How an addressable fire alarm system works
Each detector and device has an individual address. When a detector raises a fire alert, the system identifies that device so you can locate the affected area. Addressed detectors and devices can also be grouped into categories and zones, and each device can have a location name, such as First-floor lobby or First-floor reception. The guard on duty reads a room name, not a zone number.
System components
The system includes a fire alarm panel, detectors, alarm devices and supporting modules. Detection devices include addressable smoke detectors, heat detectors and multi detectors. The components are:
- Fire alarm panel (FAP)
- Addressable smoke detector, heat detector and multi detector
- Addressable hooter, strobe and manual call point (MCP)
- Isolator, which keeps the rest of a loop working if one section is damaged
- Input and output modules, which connect other equipment to the system
- Repeater panel and annunciator panel
What the system can do during a fire
The system can be programmed to carry out specific actions when it detects a fire. These can include switching off power to access-controlled doors, stopping air handling units and activating evacuation announcements:
- Switch off power to all access-controlled doors
- Switch off all air handling units (AHUs)
- Activate all speakers with an automatic voice message for immediate evacuation
Advantages of an addressable fire alarm system
Individual device addresses make fire alerts easier to locate. The system also supports detector and device health checks, expansion and easier maintenance. The advantages are:
- Easy identification of the device that raised the alert
- Lower wiring costs compared with a conventional system, since many devices share one loop
- Health checks for all detectors and devices
- Scalability, so you can add devices later
- Ease of maintenance
- Reliable operation
Brands we supply
Essatech supplies, installs and services addressable fire alarm systems in Hyderabad and Visakhapatnam. Brands include Honeywell, Honeywell Morley-IAS, GST, Honeywell Fire-Lite, Tyco Simplex, Ravel and Apollo.
What you get from Essatech
We deliver an addressable system as a complete job:
- A free site survey and a loop design with a device schedule
- Location names for every device, agreed with your team
- Supply, installation and wiring of the panel, loops and devices
- Programming of the cause-and-effect actions you approve
- A test of every device and every programmed action at handover
- Maintenance with health reports from the panel
Testing and upkeep
An addressable system reports its own health, which makes maintenance quicker. At each service visit we read the panel's fault and event logs, test a sample of devices on every loop, clean dusty detectors, check the battery and charger, and confirm the programmed actions still work. If a device shows a drift in its reading, we clean or replace it before it causes a false alarm, and every test goes in a logbook.
For builders, architects, MEP consultants, corporates, industries, hospitals and defence
Builders and architects should plan loops floor by floor, with isolators at section boundaries and space for repeaters at entrances. Hospital owners and commercial building owners gain the most, since staff see the exact room and the system runs lifts, doors and air handling. Industries use it to shut down plant on alarm, and we agree each programmed action in writing before commissioning. MEP consultants can send the loop and cause-and-effect drawings and we price and program against them. Corporates should plan one addressable network per campus. Defence establishments, including Navy and Army sites, use addressable systems in large stores and accommodation, and we quote within their security and vendor rules.
What decides the cost
An addressable fire alarm system costs more than a conventional one to buy, but the wiring is lighter. The quote depends on:
- The number of devices and loops, and the panel size
- The brand and its protocol
- Modules, isolators and the actions you want programmed
- Cable length and installation effort
