Technical Data
FAQs (6)
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 sort of smoke alarm system would I need to install for a HMO?
A.
BS 5839-6 recommends that one or two storey HMOs with an individual floor area of no more than 200sqm (not the total of both floors) should have a Grade D smoke alarm system installed. Grade D refers to mains powered smoke alarms with a back up battery power supply. The alarms can be interlinked either by wire or by radio signal and the system does not require a separate fire alarm panel. For HMOs of 3 storey or higher, a Grade A panel system would need to be installed. This can cover the whole of the building, or can be used just for the communal areas with a separate Grade D system installed for the individual dwellings. For both applications, the level of cover should be a minimum of LD3 (in all escape routes) but this may change according to the fire risk assessment.
Q. Where more than one radio-interlinked battery operated smoke alarm is installed, if the battery in one alarm failed would the other alarms be affected?
A.
If one alarm was to malfunction the other units would not be affected, if it was due to alarm failure. If the fault was with the radio-interlinking signal, then all alarms that are in the chain after the faulty alarm would be affected and they would not go off.
Q. Can a smoke alarm be fitted with a sticky adhesive pad in a let property?
A.
The sticky pad is suitable for all battery operated smoke alarms. However, we cannot judge if battery alarms are suitable for your let property, as let properties usually require mains powered alarms. There is some advice to this in the governments guides to fire risk assessments. http://www.safelincs.co.uk/Fire-Risk-Assessment/ Also see the LACoRS guide for let properties.
Q. Do I need to take out all the batteries in my radio-interlinked alarms before adding a new alarm into the system?
A.
No, you do not need to remove all the batteries. Just simply press the house code button on all the units. Please ensure that the batteries have full power as this could render the house code process incomplete.
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.
Show All 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.
