Aico Ei146RC Optical Smoke Alarm Mains Powered with Battery Back-up and RadioLINK option

• The alarm gives a fire warning when adequate smoke enters the alarm.
• This alarm is supplied with the Easi-fit base which 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 detector slides on.
• The Ei146 alarm from Aico can be controlled remotely by either a "Test, Silence, and Locate" Switch (Aico Ei1529RC) or a Manual Call Point (Aico MCP401RC). If the alarm is connected to other Ei "RC" mains powered alarms then the whole system can be controlled remotely. Up to 20 Aico Ei144RC alarms can be interconnected.
• 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.
• The Aico Ei146RC alarm has one person test feature which allows a person to test if the alarms are interconnecting. When releasing the test button, the other alarms in the system will continue to sound for a further 3 seconds so you can hear if they are linking.
• The alarm has a memory feature which will indicate if an alarm has been previously activated within a 24h period by flashing twice every 40 seconds.

Aico Ei146RC Smoke Alarm - the Operation

• 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 with 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.
