Fire Alarm

Fire Alarm Systems are developed to alert those in a building to a fire emergency, and action can be taken to protect the staff and the public. Fire alarms are part of every building but are overlooked until there is a fire emergency. Whatever the method of detection you use, once the alarm is triggered, alarms will operate to warn people that there may be a fire and to evacuate. The fire alarm system also has a remote signal system that alerts the first station.

There are different types of fire alarm systems, including:

Conventional Fire Alarm Systems

Addressable Fire Alarm Systems

Intelligent Fire Alarm Systems

Wireless Fire Alarm Systems

Conventional Fire Alarm Systems

Physical cabling is used to interconnect several detectors and call points. Signals are wired to the main control unit. Detectors are installed in zones to simplify locating the cause of the alarm. Every zone has a Fire Alarm Control Panel with an indicator lamp or a text display. The Control Panel is wired to sounder circuits that contain audible alarms.

Addressable Fire Alarm Systems

The principle of an Addressable System is almost the same as a conventional system, but each detector is given a set address utilizing a dip switch. The Control Panel determines exactly which detector or call point has initiated the alarm. A detection circuit is wired as a loop, and 99 devices may be connected to every loop. It is normal for the loop to be fitted with Loop Isolation Modules, so the loop is sectioned to make sure a short circuit causes a loss of aninsignificant part of the system.

Intelligent Fire Alarm Systems

Every detector incorporates the computer that evaluates the environment around it and communicates to the control panel if there is a fire or not. Intelligent Systems are complex and incorporate more facilities than either Convention or Addressable Systems. Very few mistaken fire alarms occur with an Intelligent Fire Alarm System.

Wireless Fire Alarm Systems

These are systems that use secure, license-free radio communication to connect to all sensors and devices with the controller. Wireless systems are simple and can provide many benefits. You don’t need wiring and fire alarms can be activated quickly.
