        GT Smoke Alarms GT240 | 240V Mains Smoke Alarm | 9V Battery Backup

        The GT Smoke Alarms GT240 is a 240V mains powered photoelectric smoke alarm designed to monitor smoke levels and provide early warning of fire hazards. The split-spectrum photoelectric sensor improves smoke detection while reducing nuisance alarms caused by dust or water vapour.

        A 9V battery backup maintains protection during power outages, while a high output buzzer exceeding 85dB at 3m delivers a clear audible alert. The GT240 supports hardwired or wireless interconnection with up to 24 alarms so all units sound when one activates. A large test and silence button, LED status indicators and optional infrared remote silence provide simple operation and maintenance.
