Mains Power, Battery Backed
The R240P runs on 240V mains for continuous operation, with a user-replaceable 9V alkaline battery that keeps it working if mains power is lost. A green LED confirms mains is on at a glance, while the red LED signals warning, fault, low-battery and memory status. The photoelectric sensor responds well to slow, smouldering fires, and the dual mesh insect guard keeps bugs out of the chamber to cut down on nuisance alarms.
Interconnect a Whole Home
Alarms can be hardwired together, up to 40 units over 150m in free field, so that when one detects smoke, they all sound. Where running cable is not practical, the optional RFMOD wireless module links up to 20 alarms by radio at 433.92 MHz, for retrofits and renovations, with up to 40 alarms interconnected in total. A hush function quietens nuisance alarms for 10 minutes.
Built for Compliance
The R240P is certified to AS 3786:2014+A1:2015+A2:2018 and listed by CSIRO ActivFire (certificate afp-3902). Interconnected photoelectric alarms are central to Queensland's domestic smoke alarm legislation, and this alarm is approved for QLD Government Housing installation, making it a practical compliant choice for landlords and property managers. For best performance and compliance, installation should be carried out by a licensed electrician.
