i-Fire Alarm System

Intelligent addressable systems overcome the limitations of detecting particular place, each fire detecting sensor or callpoint is electronically coded with a unique identification or 'address' which is programmed into the device during installation.

In this manner, the panel can ascertain whether each device is functioning correctly and also discover the amount of smoke or heat that the device is currently sensing. This technology allows the panel to make intelligent decisions as to the appropriate action to take based on the information it receives from the individual sensors.

This has many advantages, for example very slow build up of apparent smoke density seen by a sensor can cause a warning or pre alarm condition to be triggered by the alarm panel prior to the situation becoming serious enough to warrant a full alarm.

A typical practical benefit of this technology is the situation whereby airborne dust particles enter smoke detectors and mimic the appearance of smoke, over time the concentration of dust can increase to a point where it can cause the detector to falsely trigger an alarm condition. With an intelligent addressable system, a pre alarm condition will normally be triggered rather than a full alarm giving the building operator the opportunity to clean or replace the sensor rather than suffer the disruption of an unwanted false alarm.

If whilst continually interrogating the smoke and heat sensors, the panel determines that the data gathered from a specific device is appropriate to investigate either a fire, fault or pre alarm condition, it uses the unique identifying number or address to determine which device is involved. Consequently the panel can pinpoint and identify precisely which device has triggered the fire, fault or pre alarm condition.

This level of sophistication removes the need for each zone of the building to be wired as a separate circuit. For this reason intelligent addressable system components are typically connected to the panel using a small number of large loops thus greatly simplifying the installation of the system and reducing the installation cost.

Detectors instead of being simple two state devices now function as sensors continually communicating with the control panel and providing information regarding the temperature or concentration of smoke in their local environment.

Creating one step ahead in intelligency all panels can be integrated to GSM/GPRS/WEB INTERFACE.
