Aico Ei450 RadioLINK Alarm Controller, remote control switch: test, locate, and silence

In homes fitted with an interconnected fire alarm and/or carbon monoxide alarm system, it is useful to keep a controller to hand which can test the system or help locate a fire or CO leak. The Ei450 is a small, wall-mounted alarm controller with four main functions:

1. Test Alarm will activate the entire alarm system to check for malfunctions.
2. When the alarm is triggered by a possible fire or carbon monoxide leak, Locate Alarm will identify the source alarm by silencing all others.
3. Selecting Silence Alarm will silence the system in case of a false alarm.
4. The Memory function will identify whether the most recent alarm state was triggered by a fire or carbon monoxide detector.

The Ei450 also displays a pair of clear warning icons to identify triggered alarms in real-time. It is incredibly easy to use and essential for any interconnected alarm system.


The Aico Ei450 Alarm Controller is designed for use with the RadioLINK enabled Fire alarms and Carbon Monoxide alarms. It indicates if source of alarm is a fire or CO alarm. It has four main functions: Test Alarm (to test the alarms), Locate Alarm (to identify triggered alarm), Silence Alarm (to silence alarms), and Memory (to identify a previous alarm state).
