Using advanced heat sensing technology (also called Thermistek), the FireAngel WHT637 radio-interlinked heat alarm reacts quickly when significant rate-of-rise in temperature is detected. Ideal for areas where a smoke alarm could be prone to false triggering, e.g. kitchen or garage, the WHT637 is capable of wirelessly interlinking with up to 50 alarms using radio-frequency signal. Enabling all interlinked alarms to sound if one detects a fire, a wireless smoke and heat alarm system within the home would ensure you receive the earliest possible warning of fire.

Q. What smoke alarm should I use in a bedroom with an en suite bathroom?
A. It is usually recommended to install an optical smoke alarm in a bedroom. This is because optical smoke alarms are slightly quicker at detecting slow smouldering fires that can originate from upholstery type materials and over-heated wiring. Also, an optical smoke alarm would be less likely to sound a false alarm than an ionisation would, if steam/water droplets were present from the bathroom. Detectors should be installed as central to the room as possible; however for your application I would also consider the position of the en suite to make sure that the detector is not in the direct path of the joining door. This is just to try and avoid the chances of a false alarm. No detector is designed for use in bathroom areas.
Q. How do I safely dispose of my old smoke alarms?
A. Safelincs is signed up to Valpak's WEEE (Waste Electrical and Electronic Equipment) Distributor Take-Back Scheme (Registration ID: 7370). Private households can therefore drop off their electronic and electrical fire safety waste at their municipal recycling centre when they are purchasing new products from us. To find your nearest recycling centre, please visit www.recycle-more.co.uk.
Q. If the radio interlinking signal on one unit fails will the units still work as stand alone units.
A. Yes, should the radio interlinking signal fail the units will continue to sound independently should they detect a fire.
Q. Can a wireless router interfere with the radio interlinked alarms?
A. A wireless router is very unlikely to interfere with the signal of your radio interlinked alarms, as the RF signal of the smoke alarms is digitally coded.
Q. is there a different alarm sound for optical and heat sensors to tell you the difference in what kind of fire it is?
A. There is only one alarm sound type when a fire is detected, when interconnected all smoke and heat alarms will sound. However only the triggered alarm will have a rapidly flashing red indicator.
