Conventional

Conventional detectors are simply on/off devices - if there is no smoke or heat they do nothing. If there is a certain, pre-set level of smoke or heat, they switch into the 'Alarm' state. Devices are connected to one circuit, known as a zone, and each circuit is connected to a control panel. If a conventional detector goes into alarm, the control panel will be able to identify which zone has gone into alarm, but not where exactly the fire has broken out.
