The Ei450 is used to control all the alarms in a system from one place. We highly recommend fitting a control switch if you have Smoke, Heat and Carbon Monoxide alarms on the same system as it is essential that you can tell which alarm has sounded. From then you can identify which danger is present and the action you should take.
The Ei450 contains LEDs which clearly display which danger has activated the alarm – helping you to take the appropriate action as quickly as possible.

Control Switches increase the flexibility and user friendliness of the alarms by allowing the user to remotely Test, Locate and Silence alarms in the system:

Test – The alarm system
Locate – The alarm that has been activated
Silence– Any nuisance alarms

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.
