The Red 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 smoke alarms utilising the optional Red Wireless Base.

Note: 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 detector uses one non-replaceable long life 10 year lithium battery to automatically provide back-up power to the fire alarm if mains AC power fails.

  • Quick interconnect process with up to 40 Red smoke alarms using the Red wireless base
  • 90 day smoke alarm guarantee – change your mind for any reason? No worries! Return the alarms to us for your money back – no questions asked!
  • 10 year Red smoke alarm full product warranty (warranty details)
  • As this Red smoke model is hardwired to mains power it must be installed by a licensed electrician
  • Model No: R240RC
  • Excellent after sales support – see our 5 star google reviews below!

A huge thank you to Christian from Photoelectronic smoke alarm Australia. We had a huge issue with the fire inspector regarding our property in compliance with the fire and safety. I am particularly impressed with Christian with his professional manners and ability to provide advice on fire safety matters. He had given us complete information on on whom to contact and full assistance and support for all of my inquiries despite the fact that we haven’t had any prior business with him. We want to express our gratitude as with his help avoids us the unnecessary expenses.

It was the quick response to my email query that got me. Within a matter of minutes, I received a ph call in response to my email that I would be returning a couple of the Smoke Alarms, which were excess to my needs. It was the most positive exchange of words. It was unexpected, and it was a pleasant surprise to speak directly with Christian Basos from Photoelectric Smoke Alarms. Every Telstra, every Optus, every Qantas (to name a few) should have a Christian Basos in their team. What a difference that would make to our lives. Thank you Christian

Christian was extremely accommodating and professional in the multiple times I've done business with his company. I would highly recommend him to others, and look forward in continuing to working with him. The smoke alarms are great quality, and they come all interconnected, which saves me time on the job .

Such a lovely kind supportive and knowledgeable company. Made my day talking to someone who wasn’t rushing me and was a wealth of knowledge about the product. Purchased without hesitation because I knew I would have excellent after sales service from a person right here in Australia. Thanks ????
