Aico Ei181 12V – 24V Interconnectable Ionisation Smoke Alarm with Relay and Battery Back Up

The Ei181 Ionisation Smoke Alarm runs on a 12V to 24V variable DC power, and has a 9V Alkaline battery back-up. The alarm gives a fire warning when adequate smoke enters the alarm.

The alarm is supplied with an base that allows quick and simple installation of the smoke alarm head. The base automatically connects both the low voltage power and battery as the alarm slides on.

The alarm has a pair of built-in Volt free relay contacts (i.e. can be used to switch into a burglar panel).

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.

Operation of the Ei181 Ionisation Smoke Alarm

The green light on the side of the alarm will illuminate to show mains power is present.

The red indicator on the front of the alarm will flash every 40 seconds to show that it 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 10-minute period of reduced sensitivity to overcome false alarm conditions. It will then automatically reset itself.

When interconnected to other 180 Series 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 bleep every 40 seconds to indicate that the battery back-up is depleted and needs replacing.
