The Red Smoke Alarms RHA10RF is an RF wireless heat alarm rated to activate at 55–59°C using a thermistor sensor, powered by a 10-year non-removable lithium battery. The RHA10RF is certified to AS1603.3:2018 and interconnects wirelessly with up to 40 Red smoke and heat alarms across a 30-metre indoor range. It is not a smoke detector; instead, it is engineered specifically to detect heat in kitchens, bathrooms, laundries, and other spaces where steam or cooking smoke would trigger false alarms on traditional photoelectric sensors. The RHA10RF mounts on ceiling or wall and includes a test/hush button with visual LED indicators for alarm and low-battery status.
Standard photoelectric smoke alarms are prone to false activation in environments with steam or cooking fumes, forcing occupants to disable them entirely or become desensitised to alarm sounds. This creates a serious safety risk when a real fire is present. The RHA10RF solves this by responding only to heat, cutting false alarms in kitchens and bathrooms while maintaining protection in high-risk areas. Licensed electricians and renovators fit heat alarms alongside photoelectric units to create comprehensive fire detection without nuisance triggers on a single wireless mesh. No hardwiring required, no battery changes for a decade, and simple pairing with other Red alarms makes the RHA10RF the default upgrade for kitchen and bathroom fire safety in domestic rewires and renovations.
The compact 83mm-diameter unit is quick to install and pairs instantly with an existing Red wireless system, making it an ideal retrofit solution for properties where ceiling cavities are inaccessible or wall chasing is not feasible. Its 10-year sealed battery removes the annual maintenance burden that catches many households unprepared, and the wireless interconnection ensures that a fire detected by one alarm triggers all others in the house simultaneously. Occupants can silence nuisance alarms using the hush button without committing to permanent disablement, preserving fire safety across the entire network.
The RHA10RF is not a replacement for photoelectric smoke alarms and should not be used as the sole fire detection device in a home. Queensland legislation (and national fire safety standards) require photoelectric smoke alarms in bedrooms and hallways; the RHA10RF supplements these in kitchens and bathrooms where steam would cause false triggers. Install both sensor types on a single wireless network to achieve comprehensive, nuisance-free fire detection.

(RHA10RF)
The RHA10RF is a heat alarm only. It detects fire by temperature rise (55–59°C), not smoke. Use it in kitchens, bathrooms, and laundries alongside photoelectric smoke alarms to avoid false triggers from steam and cooking fumes.
The RHA10RF is a battery-powered wireless unit and does not require a licensed electrician for installation. Surface-mount installation uses only a drill and screws. However, as fire detection is safety-critical, confirm proper positioning and system pairing before relying on it.
Yes. The RHA10RF pairs wirelessly with R10RF photoelectric alarms, RHA240SL heat alarms (when fitted with RHARFM wireless module), and R240/R240RC models (when fitted with RWB wireless base). Up to 40 alarms interconnect on one network.
The RHA10RF operates at 30 metres indoor range line-of-sight, and 100 metres in free field for testing. Walls and distance reduce effective range; test pairing before relying on distant units.
The 10-year lithium battery is sealed and non-replaceable. When the battery reaches end-of-life, the alarm stops sounding low-battery alerts and must be discarded and replaced with a new RHA10RF. There are no replaceable batteries to change annually.
The RHA10RF produces 85 dB at 3 metres, meeting AS1603.3:2018 audibility standards. The hush button on the unit silences the alarm for 10 minutes (standard nuisance-alarm silence delay), allowing you to clear steam without disabling the entire network.
Once triggered, the RHA10RF sounds continuously, interconnecting wirelessly to trigger all other Red alarms on the network. The alarm will not stop sounding until manually silenced or the heat drops below activation threshold.
