Firehawk FH250 series heat alarms are part of the Fast-Fix heat alarms that have the advanced thermistor-based detection. The heat alarm has a battery backup and the operating voltage is 230 V ac and are excellent for use where smoke alarms are unsuitable. An extra-large alarm test button, alarm silence button and low battery warning are among the features of this heat detector. The green LED indicates the power of the detector and the constant flashing red Led indicates the alarms condition. You can link the detector with up to 14 other FH250 smoke or FH540 heat alarms. Push Fit wiring connections and the Fast-Fix design makes fixing and connecting the alarm easy, fast and secure.

Stand Alone Fire Alarms

Battery Operated

A comprehensive range of battery operated smoke alarms all carrying the BS Kitemark and compliance with BS5446:Pt1:1990. They are suitable for BS5839:Pt6:1995 Fire Systems grade F.

Mains Powered Interconnectable

All new properties are required by the Building Regulations to have installed mains powered smoke alarms. Refurbished properties and small commercial premises may also be required to install mains operated alarms.
BS5839:Pt.6:1995 acknowledges that all three types of detection i.e. ionisation, optical and heat detection, need to be considered depending on the installation circumstances. It is also recommended that some form of back-up is used in the event of mains failure.
Optical alarms are recommended for use in circulation spaces such as landings and hallways. Ionisation alarms are more appropriate for use in living rooms and fixed temperature heat alarms are designed for use in kitchens and garages. All alarms must be interconnected using 3 core and earth cable.

At least one alarm on each floor of the house
Max. 7.5m between alarms and no more than 3m from bedroom doors
Alarms can be wired off lighting circuits if the alarm has its own backup supply
Locate as close as possible to centre of ceiling, away from light fitting
