Ajax fire and CO sensors sit on the same hub as the burglar alarm. One app. Same phone alerts. Same Jeweller radio.
- Smoke and fire in halls, by bedrooms, and over kitchens or break rooms as the detector instructions say.
- CO near furnaces, garages, and anywhere a gas appliance lives.
They still need a clear spot on the ceiling or high on the wall. Do not hide them in a closet. Test them when you test the rest of the system.
This is extra protection, not a replacement for the smoke detectors your building code already requires. Keep those too.
