        Matelec | Photoelectric Smoke Alarm 240V RF Wireless Interconnect | 10-Year Lithium Battery Backup

        The Matelec DET-SMK-RF-AC-10 is a 240V mains-powered photoelectric smoke alarm with a 10-year lithium battery backup. It is a Type A detector with dual spectrum sensing, and it pairs wirelessly with up to 48 alarms or hardwires to up to 24. The DET-SMK-RF-AC-10 mounts to a wall or ceiling and conforms to AS 3786:2023 and AS 3786:2014.

        Retrofitting alarms into an occupied home means working around existing ceiling linings and cable runs. The DET-SMK-RF-AC-10 has a base recessed for mains cabling, so the cable lands without a large ceiling cut-away. Its mounting holes line up with standard plaster brackets, and the hinged base opens by push button at fit-off. Dual spectrum sensing reduces nuisance alarming.

        Interconnection runs either way on this alarm. Wireless pairing links up to 48 alarms on the 433.42 MHz band, and a loop terminal carries a hardwired run through each alarm position to 24 units. The No Battery, No Close catch stops the base closing with the battery left out. The alarm also carries improved EMI resilience.

        Features

        • Dual spectrum detection — reduces nuisance alarming while keeping the photoelectric response to smoke.
        • 240V hardwired supply — runs on mains power, wired into the ceiling or wall position at rough-in.
        • Wireless pairing to 48 alarms — the DET-SMK-RF-AC-10 pairs wirelessly with as many as 48 alarms.
        • Hardwired interconnect to 24 — up to 24 alarms link over a hardwired interconnect instead of the wireless pairing.
        • 433.42 MHz link frequency — the wireless interconnect runs on 433.42 MHz.
        • 10-year lithium battery backup — the lithium backup battery keeps the alarm working through a mains outage.
        • Separate hush and test button — one button covers silencing and routine testing without opening the alarm.
        • Hinged detachable base — opens by push button, so the head comes off the base by hand.
        • 85dB at 3 metres — sound output measured at 85dB three metres from the alarm.
        • Low battery audible warning — the alarm sounds a low battery warning before the backup battery goes flat.
        • AS 3786 conformance — conforms to AS 3786:2023 and AS 3786:2014, and to ISO 12239:2021.
        • 0 to 40 degrees C only — the DET-SMK-RF-AC-10 is rated for that range, and high temperatures shorten battery life.

        Where to use

        • New residential builds — the 240V hardwired supply suits alarm positions cabled at rough-in on a new dwelling.
        • Retrofits with no interconnect cable — wireless pairing links the DET-SMK-RF-AC-10 alarms without pulling an interconnect conductor through the ceiling.
        • Hardwired interconnect runs — the loop terminal carries the interconnect through each alarm position rather than terminating at it.
        • Wall-mounted alarm positions — wall and ceiling mounting are both approved, which covers raked ceilings and beam positions.
        • Standard plaster bracket ceilings — the mounting holes line up with plaster brackets already set in the ceiling.

        The DET-SMK-RF-AC-10 is rated for 0 to 40 degrees C and 5 to 93 percent humidity, so locations outside that range sit out of scope. High temperatures shorten battery life. Wireless pairing tops out at 48 alarms, and a hardwired interconnect tops out at 24.

        (DET-SMK-RF-AC-10)

        The DET-SMK-RF-AC-10 conforms to AS 3786:2023 and AS 3786:2014, and to ISO 12239:2021. It is a Type A photoelectric smoke detector running on a 240V mains supply with battery backup.

        Installation requires a licensed electrician, because the alarm connects to a 240V mains supply. The base is recessed for the mains cable and the mounting holes line up with standard plaster brackets. The hinged base opens by push button for fit-off.

        Up to 48 alarms pair wirelessly, running on the 433.42 MHz band. Wireless pairing suits retrofits where there is no interconnect conductor between alarm positions.

        Up to 24 alarms link over a hardwired interconnect. A loop terminal is provided, so the interconnect conductor carries through each alarm position rather than terminating at it.

        A 10-year lithium battery provides backup during a mains outage. The alarm sounds an audible low battery warning, and a No Battery, No Close catch stops the base closing with no battery fitted.

        Warranty runs for 7 years for domestic use, starting from the invoice date. The warranty is void if a licensed electrician does not install the alarm.
