Aico Ei146 Optical Smoke Alarm - Mains Powered (Replacement To Former EI141)

The Aico Ei146 Optical Smoke Alarm runs on 230V AC mains power, and has a 9V PP3 Alkaline Battery back-up capable of lasting up to 4 years in standby 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 an 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 alarm slides on.

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.

Due to the EI141 Ionisation smoke alarm being discontinued late 2021, the EI146 optical smoke alarm is the direct replacement to former Ionisation smoke alarm. Please note that the bases are exactly the same and the EI146 will fit directly into the EI141 older base without any issues.

Operating Functions

• The green indicator will illuminate to show mains power is present
• The red indicator will flash every 40 seconds to show that the alarm has performed an automatic self test
• The red indicator will flash rapidly to show an alarm condition for the alarm that has triggered
• The Test/Hush button will either silence false alarms (if briefly pressed) or to perform a self test (if pressed and held)
• In Test mode the alarm will perform a self test and sound the horn
• In Hush mode the alarm enters a ten-minute period of reduced sensitivity to overcome false alarm conditions. It will then automatically reset itself
• When interconnected to other Ei mains powered alarms, an alarm on one unit will trigger all other interconnected alarms (only the triggered alarm will flash a red indicator)
• The alarm will emit a beep every 40 seconds to indicate that the battery back-up is depleted and needs replacing
