Honeywell HF500 gas alarms. A complete solution you can trust !
The HF500 is hard-wired which ensures that the alarm is always connected to the mains power supply. It also prevents the unit being accidentally unplugged which would stop the alarm from working and could also create a spark that ignites the gas.
The Honeywell H450EN is the ideal CO alarm for the home, caravan or boat and can provide up to 7 years maintenance free operation due to its advanced electrochemical cell technology. The batteries are tamper-free as they are sealed inside the alarm preventing access by the user as they do not need replacing for the whole 7 year life of the alarm.
