Siren and plug-in adapter installation


I’m assuming there’s no option to bring the cable through the back of the siren so it’s not visable from outside?

Can you have mains power without D batteries, do the batteries still draw charge once mains power is connected or are they only utilised in the event of mains power failure.

Maybe have mains and rechargeable battery pack for a fit and forget install?


Hi @Jaysadie. We have this Help Center page on how to hardwire the Outdoor Siren. You do not need the D batteries in it while it is hardwired. If you do leave the D batteries in while it is hardwired, the batteries will not be used unless power is lost from the hardwiring. This and other information can be found in this Help Center article for the Outdoor Siren.
