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.
With self-charging back-up batteries, these mains-powered smoke and heat alarms from Firehawk won't need new batteries for their full 10 year lifespan. Ideal for Grade D1 and Scottish installations.

These Firehawk optical smoke and heat alarms are mains-powered and fitted with sealed self-charging back-up batteries designed to last their full 10 year lifespan without needing to be replaced. Suitable for Grade D1 installations and Scottish regulations, Firehawk FH250RB optical smoke alarms and FH450RB heat alarms can interlink in a system of up to 15 alarms to warn all occupants throughout the whole house if one detects a possible fire. The supplied Fast-Fix bases also allow for the easy replacement or swapping of smoke and heat alarm heads from the same range if required. An "end of life" warning chirp will sound when the whole unit needs replacing after 10 years, but this can be silenced for 10 hours in case it starts during the night.
The table below shows all alarms which can interlink via cable with the Firehawk FH250RB and FH450RB 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.
