Fireangel WHT-630T Wireless Interlink Heat Alarm with Sealed In Lithium Battery by Fireangel

Stopped working after couple of months. Linked to other detectors some of which also stopped working and difficult to know which detector was the problem

very good

Thanks very much

Easy fit links together well very good product

Purchased a complete set including 1 x heat detector 1 x carbon monoxide detector and 1 x smoke detector- all wireless units connected in a network. Everything went in easy and worked fine for about 12 months. The units began to fail with beeps and battery failure. Tried on numerous occasions (phone and email) to contact Fireangle and was completely ignored with zero response.Very irresponsible for a company supposedly helping to protect my family and home.
