Learn more by watching our GT Smoke Alarms GT240-5Bundle | 5 Mains Powered Smoke Alarms + Remote | 9V Backup video.
The GT Smoke Alarms GT240-5Bundle is a mains-powered photoelectric smoke alarm kit containing five GT240 alarms and one GTREMOTE wireless controller. Each GT240 runs on 240V AC mains power with a replaceable 9V alkaline battery backup, and uses split-spectrum photoelectric sensing to detect smouldering fires before visible flame. The GT240 hardwire interconnects up to 24 alarms, so smoke detected by one unit sounds every alarm on the circuit. Each alarm is certified to AS 3786:2014 and is CSIRO ActivFire listed.
New builds and substantially renovated homes must run mains-powered smoke alarms, not battery-only units. The alarms also have to be photoelectric and interconnected, so one detection sounds the lot. The GT240-5Bundle covers a standard three-bedroom layout with five 240V alarms in a single carton. Each unit hardwire interconnects up to 24 alarms and holds a 9V alkaline backup for mains failure.
The GT240-5Bundle lands on site as a single part number, removing the pick across five alarm lines and a controller. Burnt toast at midnight does not require a ladder. Any infrared remote already in the household, usually the television or air conditioner remote, silences the alarm immediately. Each GT240 also tests and silences from its central push button, and the included GTREMOTE controller repeats those functions from a wall position. The 9V alkaline backup is replaceable, so a depleted battery does not condemn the alarm.
The GT240 is rated for indoor installation only and should not be fitted in outdoor or exposed locations. Photoelectric sensing is not suited to kitchens, bathrooms, or garages, where cooking steam, shower vapour, and vehicle exhaust cause nuisance alarms. Keep installation within the -10C to +55C operating range and below 95% relative humidity, non-condensing.
(GT240-5Bundle)
Each GT240 alarm is photoelectric, interconnectable, and certified to AS 3786:2014, and is CSIRO ActivFire listed. Mains-powered photoelectric interconnected alarms meet the standard required in new builds and substantially renovated dwellings. Confirm alarm placement and quantity for the specific dwelling with the installing electrician.
A licensed electrician is required. Each GT240 runs on 240V AC mains power and connects to fixed wiring, which is licensed electrical work in Australia. The alarms mount to the ceiling and interconnect over hardwired interconnect cable. The GTREMOTE controller needs no wiring and mounts to the wall or sits free-standing.
The GT240 hardwire interconnects with up to 24 alarms on a single interconnect circuit. Once one alarm detects smoke, the signal is pushed to every alarm in the network and they sound in unison. The five alarms in the bundle can be expanded with additional GT240 units up to that limit.
The GT240 is mains-powered, drawing 240V AC with a replaceable 9V alkaline battery backup for mains failure. Battery-only alarms such as the GT10RF run on a sealed 10-year lithium battery with no mains connection. New builds and substantial renovations require mains-powered alarms, which is where the GT240 applies.
Yes. A false alarm can be hushed with almost any household infrared remote, such as a TV or air conditioner remote, with no pairing or programming needed. The included GTREMOTE controller also silences linked alarms from the wall. The central push button on each GT240 tests and silences directly, for 9 minutes.
The 9V alkaline backup battery in each GT240 is replaceable and rated for one year of backup service. A yellow indicator flashes once per minute to flag a low backup battery. Smoke alarms are generally replaced 10 years from the date of manufacture, regardless of backup battery condition.
GT High Performance smoke alarms carry a 10-year warranty for domestic and commercial use, running from the invoice date. The warranty covers manufacturing defects. Keep proof of purchase, as it is required for any warranty claim.
The GT240 is rated for indoor installation only, between -10C and +55C and below 95% relative humidity, non-condensing. Photoelectric sensing is not suited to kitchens, bathrooms, or garages, where cooking steam, shower vapour, and vehicle exhaust trigger nuisance alarms. Outdoor and exposed locations are outside the rating.
