EI Optical Sensor Smoke Alarm

I bought one of these, three of the ionisation ones (Ei Electronics Smoke Alarm with Smartlink RF Digital Wire Free Interconnection), and a remote control test switch (Aico EI411H RadioLINK Remote Control Switch with Test, Hush & Locate Functions). They all work perfectly with each other without the hassle of hard wiring, and create a completely wireless system without the need to go around reaching up to push the test buttons on individual alarms. The test function on one alarm (or the remote control), will trigger all alarms to enter test mode at once.

Excellent product & quick delivery, very happy & would recommend.

Works great, and very reassuring to know that if a fire started in my garage (I have appliances in there) I will now hear it in my house. However, the design is exactly the same as a smoke alarm I bought in 1985. Please encourage more people to fit smoke alarms by making them a little smaller and more attractive.

ordered on behalf of other. Came as advised

EXCELLENT PERFORMANCE

working well
