Key Features

• 140MM RETROFIT BASE: Extra-wide hinged baseplate helps cover old paint marks, screw holes and discolouration from previous smoke alarm installs, making the HG140AC suited to replacement work without extra surface touch-ups.
• 240V AC MAINS POWER: Runs on 240VAC 50Hz with a replaceable 9V battery backup, helping the alarm continue operating during power outages while red and green LEDs show alarm, power and low battery status.
• PHOTOELECTRIC SENSOR: Uses photoelectric sensing with an ultra-small insect screen over the chamber to help detect smouldering fire smoke while reducing nuisance activations from dust, insects and bugs.
