The Brooks EIB146E is a photoelectric smoke alarm powered by 230V mains with a 9V alkaline battery backup, designed for residential and light commercial ceilings. The EIB146E detects slow-burning fires (smouldering smoke) before visible flame develops and complies with AS 3786:2014 for Australian installation. It is supplied with an Easi-fit base and screw-fixing hardware for straightforward ceiling installation.
Existing ceiling installations often require alarm replacement due to age, failed units, or upgrades to dual-voltage operation. The EIB146E fits standard Easi-fit bases and accepts bigger wire terminals (3 x 1.5mm conductors), reducing installation friction when wiring multiple alarms into a hardwired circuit. Battery backup ensures continuous monitoring during power outages, a critical requirement when replacing older single-voltage units across a property.
Electrical contractors and property managers appreciate wired interconnect capability and the option to add wireless interconnection with an EIB168RC RadioLINK base. Specifying the EIB146E on retrofit and new-build jobs yields quick installation and standard compliance without special components. The alarm self-tests every 40 seconds and flags any fault condition with an audible beep, reducing callback risk on final inspection.
The EIB146E is not suitable for locations exposed to wind, rain, or moisture (external eaves, open verandahs, unventilated damp spaces). It is not intended for heat-sensitive environments where sustained temperatures exceed 40°C. Do not install in kitchens where cooking fumes may trigger nuisance alarms; if kitchen installation is required, use a heat alarm or a photoelectric/heat dual-sensor instead.
Verified Sparky Direct customer reviews: Brooks EIB146E (EIB146E)
Quick delivery and works as it should. No complaints. — R Pritchard
One of the best brands on the market. — Fraser Coast Smoke Alarms
They had what I needed at a very good price. Delivery was very quick over a weekend, I was kept informed and they arrived on time. With the courier actually coming to the door to hand deliver the package. No complaints at all. — RickN
(EIB146E)
The smoke alarm is powered by 230V AC and includes a 9V alkaline battery backup, ensuring it remains operational even during power outages. The battery provides up to 3 years of continuous standby operation if mains power fails.
The EIB146E has a 10-year nominal product life. Most manufacturers recommend replacement after 10 years or at the end of the warranty period, whichever is earlier, to ensure reliable sensor performance.
Yes. The EIB146E can be hardwired to other Easi-fit alarms on the same mains circuit, so all units sound if one detects fire. Wireless interconnection is possible if you fit an EIB168RC RadioLINK base to each unit.
The alarm uses a 9V alkaline battery (user-replaceable) for backup power during mains outages. The battery provides continuous operation for up to 3 years in standby mode.
The silence (or hush) button silences the alarm for 10 minutes, allowing time for the cause of a nuisance alarm (e.g. cooking fumes) to clear. The alarm will reactivate after 10 minutes if smoke is still present.
The EIB146E produces an 85 dB(A) alarm tone at 3 metres, which meets Australian residential smoke alarm standards for audibility in occupied rooms.
Yes. The alarm is certified to AS 3786:2014 and approved for use under Queensland's Fire and Emergency Services requirements. It complies with all relevant Australian and New Zealand electrical standards for mains-powered smoke alarms.
