![]() ![]() Each bell or alarm sounder in this system is connected via a separate two-core wire to a dedicated loop. ![]() All the detectors and manual call points in the zone are hardwired to a dedicated circuit on the control panel. In this system, a building is divided into a number of detection zones with one or multiple detector in a zone. There are two main types of fire alarm – Conventional and Addressable.Ĭonventional (also four-wire) fire alarm systems are less expensive to purchase and are mostly used in smaller properties such as shops and restaurants. The fire alarm systems we use today may involve smart sensors, intelligent control panels and integration with other building services, but the core essence of fire alarm systems hasn’t changed – give the the occupants of buildings an early and clear warning of a fire. It is a key recommendation in any fire prevention plan. 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. Fire alarm systems (also commonly called smoke alarm and a 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.
