The mains powered Firehawk FHN250BB is an optical smoke alarm with an alkaline battery backup, which is ideal for Grade D2 installations in locations such as living areas, bedrooms, hallways and landings. The push-fit base makes for quick and easy installation of the smoke alarm. In one system, this alarm can interlink with up to 14 other Firehawk smoke alarms from the FHN250 and FHN450 ranges. This alarm comes with a 6 year manufacturer's warranty for peace of mind, as well as a test and silence button which covers the face of the alarm for ease of use. Featuring TSE-Technology and an X-Profile sensing chamber, this reduces the number of false alarms and ensures that that slow smouldering fires are detected quickly.
Please Note: these FHN series alarms are not compatible with the older FH models.
