Product Description
The Ei141 is an Ionisation Smoke Alarm that runs on 230V AC mains power, and has a 9V alkaline battery back up in the event of mains failure. The 9V battery will last for up to 4 years in standby mode, and capable of powering the smoke detector for up to 2 years in the event of mains failure.
The Ei141 is supplied with the Easi-Fit base that allows very quick and simple installation of the smoke alarm, combined with simple detector head removal and replacement. The Easi-Fit base automatically connects both mains power and battery as the detector head slides on to the Easi-Fit base.
The Ei141 has other advanced features such as the ability to interconnect up to twelve alarms to allow all alarms to sound if just one of the interconnected alarms should be triggered.
The Ei141 has built in circuitry to aid suppression of voltage transients and RF interference to further reduce the chances of false alarms under such conditions. Applications
Designed for applications where the budget is a key consideration and there is no requirement for lithium power cell back-up, the 140 Series provides an alkaline battery back-up instead of rechargeable cells. Further cost savings are possible through the use of Ei's innovative and totally unique Easi-fit technology, as there is no need to purchase additional wiring enclosures, mounting kits, leads or connectors. In a field where time is money, the fact that Easi-fit alarms are simpler and quicker to install ensures even greater savings. Main Features
