More on Mains Powered Alarms

What is a mains powered smoke or heat alarm? Open

A mains powered alarm is connected directly to your property’s electrical supply and may also include a backup battery. These alarms are more reliable and are often required by building regulations in rental and new-build properties.

Do mains powered smoke alarms need a battery? Open

Yes. Most mains alarms include a backup battery to ensure continued protection during a power cut. Some models feature sealed, tamper-proof lithium batteries with a 10-year lifespan.

Can mains powered alarms be interlinked? Open

Yes. Most mains powered alarms can be interlinked, meaning if one alarm is triggered, all connected alarms will sound. Interlinking can be hardwired or wireless, depending on the model.

Are mains powered alarms better than battery operated alarms? Open

Mains powered alarms offer continuous power and are considered more reliable. They're often required in properties subject to building regulations, but high-quality battery-only models can still be suitable in many domestic settings.
