FireAngel WHT-630Q Wireless Interlink Heat Alarm is rated 4.6 out of 5 by 12.
Rated 4 out of 5 by from Wireless alarms made easy!! Replaced 2 smoke alarms and 1 heat alarm in a rented property which didn't have interlinked alarms. This couldn't be easier in the absence of hard wired units. Simple to install and I have happy tenants and a happy landlord!

Rated 5 out of 5 by from Very pleased with alarms. The landlord required the alarms linked in the house but not possible to lift floors to hardwire. I was impressed with these. Very easy to set up and looked smart as well.

Rated 5 out of 5 by from Easy to install Had to get interlinked smoke and heat alarms to get extension signed off. These were cleared by building regs and are so easy to install and interlink. I recommend them.

Rated 1 out of 5 by from Safety? Fitted a Heat sensor and smoke alarm 01/17. No problem with communication and set up. Now after ca 13 months both tweet low battery! Not good for a supposed 10 year battery life and 5 year guarantee. Needless to say both will be returned to Screwfix for a full refund, there is no price on safety.

Rated 5 out of 5 by from Good Alarm Great alarm, all of the alarms go off at the same time in a 3 floor house. Comes with a helpful manual to explain how to link the alarms, positioning and any other questions a DIY'ER would have. Design also looks nice and is easy to fix to the ceiling. I did however spend quite a bit of time pairing up all 7 alarms, and it doesn't really help that the alarm goes off when you link up the alarms.

Rated 5 out of 5 by from Easy to set up. I had 2 heat detectors and 2 smoke detectors to install. The battery powered radio linked Fireangel units were easy to install. I did set the radio links before I fixed them to the ceilings (setting the radio link is very easy but you only have a 5 second window so it made sense to do this step before fitting). I would recommend this product, as for reliability only time will tell.

Rated 5 out of 5 by from fire safety made easy Bought two of these for kitchen and garage. Easy to install and link with smoke alarms bought at same time. Very loud, test one and all the others sound off in turn, kids love it!

Rated 5 out of 5 by from Very good product I bought this together with the smoke and CO detectors in the same range. All very easy to fit and interlink. Fitting instructions clear and precise. Extremely loud alarms with neat cycle test feature and facility to see which alarm triggered the others. Highly recommend.
