Frequently Asked Questions

Are mains-wired alarms better than battery-only ones?

Yes — they’re always powered, keep a battery backup for outages, and can be interlinked so an alarm in one room triggers every alarm in the property.

How many alarms does a typical home need?

As a guide, one smoke alarm per floor plus a heat alarm in the kitchen and a CO alarm near any fuel-burning appliance — we confirm exact positions on site.
