FIRE ALARM SYSTEM

Also Commonly Called Smoke Alarm & Smoke Detector

Provide a means to detect and identify a fire or a potential fire outbreak in a building warn the occupants of the building about the fire via audible alarm and potentially notify emergency response professionals. The main components of a fire alarm system are typically the smoke detectors (and other detectors like heat, gas detectors), manual call points (also called ‘break glass’) which enable a person who physically detects fire to raise the alarm, bell or alarm sounders, flashers, and control panel (central control and indicating equipment) which is the brain of the system. Some advantages of fire alarms include an early warning benefit and the potential to save life and property, low cost and the opportunity to place the device in chosen locations. It is a key recommendation in any fire prevention plan.

Addressable Fire Alarm System

An addressable fire alarm system is made up of a series of fire detectors and devices that are connected back to a central control panel. With addressable systems, each device has an address or location, enabling the exact detector that was triggered to be quickly identified. This makes addressable alarm systems ideal for large buildings, particularly commercial premises spread over a wide area.

Conventional Fire Alarm System

A conventional system employs one or more initiating circuits, connected to sensors (initiating devices) wired in parallel. These sensors are devised to decrease the circuits resistance when the environmental influence on any sensor exceeds a predetermined threshold. In a conventional system the information density is limited to the number of such circuits used.
