This is the Aico Ei450 RadioLINK / RadioLINK+ / SmartLINK alarm controller for controlling all the alarms in a system from one convenient place. This alarm controller is highly recommended if you have Smoke, Heat, and Carbon Monoxide Alarms on the same system, since it is essential to tell which alarm has sounded. The Aico Ei450 contains LED indicator icons which clearly display which danger has activated the Alarm, and from there you can identify which danger is present, thus taking the appropriate action. 

Please note: this item is non-returnable; due to the nature of this item, it has an electronic component and sensor, and we cannot take this item back for a refund as "unwanted".

The Ei450 is powered by a tamper proof, sealed in lithium cell giving a completely wire free installation with a 10 year life and connects wirelessly using RadioLINK interconnection technology, so once in place you will need to House Code the switch into the alarm system.

This alarm controller is powered for life by a tamper proof, sealed Lithium battery; it is completely wireless and can be wall-mounted or free standing, thus giving you more freedom on its location. It contains the RadioLINK wireless technology enabling communication with up to 12 others RadioLink, RadioLINK+, and SmartLINK Alarms and Devices. An interconnected system will enhance early detection and warning of danger. 

In standby the Alarm system can be easily tested by just pressing the central button; this will test and sound all the interconnected Alarms for a short period of time. 

When the system is activated the triggering Alarm can be identified and located by simply pressing the central button. Then the Aico Ei450 will identify the triggering Alarm and indicate whether it has been triggered by a Smoke, Heat, or Carbon Monoxide Alarm by a flashing indicator icon. Once identified, the alarm can be silenced by pressing the central button again. 

The System Diagnostics mode allows an extended two minute "Long Test" period to be selected. it also allows a previously triggered Alarm to be identified; this is known as the "Check Alarm Memory Test".

Please note that the 10-year guarantee period is from the year of the manufacture and not from the year of purchase. Therefore, if the alarm is purchased 5 years after the manufacture (for example), the guarantee is only for 5 years.
