Discontinued Product - No Compatible Replacement
Please Note: The manufacturer has discontinued this FH mains-powered alarm series and is no longer supplying compatible alternatives. Since it is not possible to interlink alarms from different manufacturers, it is recommended to replace all FH models in the premises with Firehawk's new FHN range.
These Firehawk mains-powered smoke and heat alarms with hardwire interlink and replaceable AAA alkaline back-up batteries are suitable for Grade D2 systems to warn all occupants of a fire.
£18.83 inc VAT
£15.69 ex VAT
The FH250BB optical smoke alarms and FH450BB heat alarms from Firehawk are mains-powered alarms with hardwire interlink, allowing up to 15 compatible alarms in the house to sound a warning to occupants when one detects a possible fire. These models feature replaceable AAA alkaline back-up batteries to ensure continued fire detection during a power cut, or if mains-power is turned off for other reasons like decorating or a blown light bulb. The unique Fast-Fix mounting base design allows alarms to be easily removed for cleaning and replacing batteries without needing to cut the power or worry about wiring, and the alarms will chirp an "end of life" warning (which can be silenced overnight) when the whole unit needs replacing after 10 years.
Please Note: these FH series alarms are not compatible with the newer FHN models.
The table below shows all alarms which can interlink via cable with the Firehawk FH250BB and FH450BB mains powered smoke & heat alarms.
Please Note: these FH series alarms are not compatible with the newer FHN models.

The best location to install your smoke alarm is in the centre of the ceiling rather than on the wall.
During a fire, smoke initially rises and then spreads horizontally. Placing the smoke alarm in the centre of your ceiling means that it is closest to all four points of your room. This ensures that you receive the earliest possible warning of a fire.
For more information, read our guide to positioning your smoke alarm and guide to which smoke alarms are best for each room.
If you have any questions or would like more information about this product you can ask one of our specialists.
