Product Description

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’s 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 LED’s which clearly display which danger has activated the alarm – helping to you take the appropriate action as quickly as possible.
