Heat Detectors – In some areas of the house, it is important to use a heat alarm that senses fire by air temperature, rather than a smoke alarm that senses particles in the air. The installation of heat alarms in attics (finished or unfinished), furnace rooms or garages is recommended, since these locations occasionally experience conditions that can result in improper operation of smoke alarms. They will not react to smoke and should not be used to replace smoke alarms, but as a supplement to a complete smoke alarm system.
Heat detectors – A working smoke alarm is essential. It provides vital early warning and extra time to escape if there is a fire. Every home should have at least one working smoke alarm. Working smoke alarms cut the risk of dying in a home fire by 50%, and that’s important because a home fire starts every 83 seconds! The faster you know about a fire, the faster you can start moving your family outside.
How do Ei Ionisation and Optical Smoke Alarms work?
Ionisation Smoke Alarms contain a small sealed ionising source which causes a small electrical current to flow through the air in the smoke chamber. Smoke particles entering the chamber reduce the current, this is sensed by the electronics and when a pre-set threshold level is reached the alarm will sound.
Optical Smoke Alarms send a pulsed beam of infra red light through the smoke chamber periodically. If visible smoke is present, it scatters the light on to the photodiode light receiver and this is detected by the electronics causing the alarm to sound. Ei Optical Alarms are individually calibrated to ensure correct operation and to reduce the risk of nuisance alarm.
