The Ei166e Optical Smoke Alarm is fitted with a proprietary photoelectric sensor to quickly sense low energy smoke particles from smoldering fires. Powered by 230V AC with a rechargeable 10 year built in battery backup supply to ensure continuous operation (up to 4 months) in the event of a power failure.
The Alarm is supplied with the "Easi-fit" base to facilitate quick and simple installation, combined with easy detector head removal and replacement. The Easi-fit base automatically connects both mains power and battery as the detector head slides on.
The Ei166e may operate as a standalone Alarm or may be interconnected via hardwire or wirelessly with the RadioLINK+ module Ei100MRF (sold separately) to communicate with compatible Ei Alarms and accessories. Up to 12 devices can be interconnected.
The Alarm self-checks its sensor, battery voltage and internal circuitry every 40 seconds. A fault condition will be indicated by a short beep every 40 seconds.
The large Test and Hush button allows the user to check the operation of the Alarm. This will check the sounder, battery voltage and internal circuitry.
The memory feature allows an Alarm that has previously activated to be easily identified. This is indicated by 2 red led flashes every 40 seconds for 24 hours (after the event).
