Photoelectric 230 Volt Smoke Alarm with 9 Volt Alkaline battery

The EIB146e is a Photoelectric Smoke Alarm with 230V AC mains power supply with a replaceable Alkaline battery back-up.


The EIB146e is supplied with the Brooks Easi-fit™ base to facilitate quick and simple installation, combined with simple smoke alarm head removal and replacement. The Easi-fit™ base automatically connects both mains power and battery as the smoke alarm head slides on.

The EIB146e may operate as a standalone Alarm or may be interconnected to other Alarms via a wired or wireless system. For a wireless system, each Alarm must be fitted with an EIB168RC RadioLINK™ base. When interconnected, all alarms in the system will sound when smoke is detected.

The Alarm is fitted with a Test / Silence button to facilitate frequent testing of your Alarm and System. The Silence function allows the Alarm / System to be silenced in the case of a false / nuisance alarm, e.g. cooking fumes.

The memory feature allows an Alarm that has previously activated to be easily identified (the red LED flashes twice every 40 seconds for 24 hours).
