The Ei141RC is an Ionisation Smoke Alarm that runs on 230V AC mains power, and has a 9V PP3 Battery back-up capable of lasting up to 4 years in stanby mode and capable of powering the alarm for up to 2 years without mains power.
The alarm gives a fire warning when adequate smoke enters the alarm.
The alarm is supplied with the Easi-fit base that allows very quick and simple installation of the smoke alarm, combined with simple alarm head removal and replacement. The Easi-fit base automatically connects both mains power and battery as the detector slides on.
The alarm can be contolled remotelyby either a "Test, Silence and Locate" Switch (Ei1529RC) or a Maunal Call Point (MCP401RC). If the alarms is connected to other EI 'RC' mains powered alarms then the whole system can be controlled remotely. Up to 20 alarms can be interconnected.
The alarm has other advanced features such as built in circuitry to aid suppression of voltage transients and RF interference to further reduce the chances of false alarms under such conditions.
The alarm has a one person test feature which allows a person to test if the alarms are interconnecting. When releasing the test button, the other alarms in the system will continue to sound for a further 3 seconds so you can hear if they are linking.
The alarm has a memory feature which will indicate if an alarm has been previously activated within a 24 hour period by flashing twice every 40 seconds.
