The Red brand 240V hardwired smoke alarm is a popular seller amongst our customers who wish to replace an existing hardwired alarm with an interconnectable photoelectric smoke alarm. Your electrician can physically interconnect these 240V hardwired alarms together by installing cabling in the ceiling space.

If this is not preferable, these alarms can also be wirelessly interconnected with other Red branded smoke alarms utilising the optional Red Wireless Base.

(one Red Wireless Base is required for each Red 240V hardwired alarm in the same network i.e. 3 x hardwired alarms = 3 x wireless bases).

This smoke alarm uses one replaceable 9V battery to automatically provide back-up power to the alarm if mains AC power fails.

  • Quick interconnect process with up to 40 Red smoke alarms using the Red wireless base
  • 90 day guarantee – change your mind for any reason? No worries! Return to us for your money back – no questions asked!
  • 10 year full product warranty
  • As this model is hardwired to mains power it must be installed by a licensed electrician
  • Excellent after sales support – see our 5 star google reviews below!

I was unsure what setup was best for my place, so I rang them. Spoke with Christian and he guided me in the right direction. I ended up getting the Red Wireless Smoke Alarm bundle when they were on special. Really good price for the product. They were delivered promptly and exactly as described. Thanks Christian for letting me pick your brain. They're exactly what I wanted.
