Mains Powered Smoke Alarms & Heat Alarms with Self-Charging 10 Year Back-up Battery - Firehawk RB Series

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.
