Conventional fire alarm systems are a 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.
A system has up to 32 zones of detection. 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 utilise a separate circuit.
There is no way of programming devices to activate in certain ways, so the system provides a one in all out scenario.
