The Firehawk FHH10-RF heat alarm is fitted with a sealed lithium battery designed to last the lifetime of the alarm. The combined test/hush button is also used to silence low battery warnings for up to 10 hours while still remaining in full detection mode giving you peace of mind while you sleep. The radio interlink allows the FHH10-RF to be wirelessly connected in a system of up to 20 smoke, heat, and hard of hearing alarms, ensuring you are alerted to a fire or CO warning in one part of the premises from any other room with a detector.
Please note: the battery in the wireless base is expected to last at least 7 years under normal use - when the battery has depleted in the base, the whole unit will need to be replaced.

A great product but even better was the service from Safelincs who also absorbed the delivery costs and offered further installation advice if I needed it. This is the second time I have bought all my fire alarm systems from them and would definitely recommend them to anyone else.
