Conventional fire alarm systems are the most basic way of providing a fire alarm for protection. An area is wired as a circuit (normally called a zone), starting at the control panel and ending at the last device. Smoke detectors, heat detectors and call points are placed on this circuit. A number of zones are required, depending on the building’s layout and size.
If an alarm occurs, the area affected shows up on the control panel in red L.E.D. The area then has to be searched to find out which device went into alarm – indicated by red L.E.D. on the device itself. Detectors and call points are run on one circuit, while sounders are on a separate circuit.
Addressable fire alarm systems are a more advanced way of providing fire alarm protection. The area is wired as a loop, starting and ending at the control panel. Smoke detectors, heat detectors, call points and sounders are placed on this loop. Sometimes a number of loops might be needed , depending on the building’s layout and size.
If an alarm occurs, both the location of the alarm and the affected device is indicated on the control panel. The device will also display a red indicator light to highlight its location.
