Learn more by watching our Red Smoke Alarms R240 | Photoelectric Smoke Alarm 240v/9v | Interconnectable video.
The Red Smoke Alarms R240 is a 240V mains-powered photoelectric smoke alarm with a 9V battery backup, designed to detect smouldering fires in residential ceilings. The R240 hard-wires into mains power and interconnects with up to 40 Red alarms, so a trigger in one room sounds every unit. It is certified to AS 3786:2014 and complies with Queensland 2022 smoke alarm legislation.
Queensland law now requires photoelectric, interconnected smoke alarms in every bedroom, connecting hallway, and storey of leased and sold homes. Many of these jobs are swap-outs of expired 240V units that were never interconnected and well past their ten-year mark. The R240 covers that work directly: it is photoelectric, hard-wired, and interconnects across the dwelling so one detection point wakes the whole house.
Licensed electricians fit the R240 as a straightforward replacement for tired hardwired alarms, landing the new unit on the existing ceiling point. The 240V model interconnects with up to 40 units over standard alarm cable, so a full-house upgrade runs off one system across every room. At this price point the R240 is an easy line item on a compliance quote, and the low-profile housing sits flat against the ceiling.
The R240 is rated for indoor installation only and should not be fitted in outdoor, damp, or exposed locations. It is built for surface mounting in conditioned interior spaces between 0 and 45 degrees C, so unheated or uncooled areas outside that range fall outside its rating. The R240 detects smoke through a photoelectric sensor and does not sense heat or carbon monoxide.

(R240)
The R240 is certified to AS 3786:2014 and complies with Queensland's 2022 smoke alarm legislation, which requires photoelectric, interconnected alarms in all bedrooms, connecting hallways, and on every storey of leased and sold homes. The alarm is CSIRO certified to the current standard.
Installation of the 240V hard-wired R240 must be carried out by a licensed electrician, as it connects to mains power. The alarm surface-mounts to the ceiling with the supplied screws and links to other units over standard interconnect cable. The warranty is void if the alarm is not installed by a licensed electrician.
The R240 hard-wires and interconnects with up to 40 Red 240V alarms over standard interconnect cable. When one alarm detects smoke, every connected unit sounds across the dwelling. All hardwired alarms in the chain must share the same interconnect wiring for the link to work.
Photoelectric alarms like the R240 sense the larger smoke particles from smouldering fires, the most common house-fire type, and respond earlier to slow-burning smoke. Ionisation alarms react faster to flaming fires but trigger more cooking nuisance alarms. Australian guidance favours photoelectric alarms for homes.
The R240 runs on 240V mains power, so the 9V alkaline backup battery is only drawn on during a power outage. The backup battery has an approximate one-year service life and should be checked as part of routine alarm maintenance. The alarm itself carries a ten-year manufacturer warranty.
Red Smoke Alarms provides a ten-year full parts and labour warranty on the R240 for both domestic and commercial use, starting from the invoice date. Faults are handled directly by Red Smoke Alarms through a national network of service agents, so the alarm does not need to be returned to the retailer.
The hard-wired R240 can be converted to wireless interconnection by fitting the Red RWB wireless base in place of the standard base, linking it to other Red alarms without running interconnect cable. The Red RAC controller can also connect once a wireless base is fitted. Both parts are sold separately.
The Red Smoke Alarms R240 is available online from Sparky Direct, with Australia-wide delivery to any state or territory including regional areas. Sparky Direct is an Australian electrical wholesaler established in 2005, supplying more than 500,000 customers with transparent trade pricing.
