Smoke, heat and carbon monoxide alarm installation
Fire and Smoke Alarms
Fire and smoke alarm installation covers fitting interlinked smoke alarms, heat alarms and carbon monoxide detectors to current standards (BS 5839-6), for homeowners and landlords meeting their legal alarm requirements.
Definition
What fire & smoke alarms involves
Domestic fire detection uses smoke alarms in hallways and living areas, heat alarms in kitchens (where smoke alarms would give frequent false alarms), and carbon monoxide alarms near fuel-burning appliances. Landlords in England are legally required to have a working smoke alarm on every storey and a carbon monoxide alarm in any room with a fuel-burning appliance.
Suitable for
- Landlords meeting legal smoke and carbon monoxide alarm requirements
- Homeowners upgrading to interlinked mains-wired alarms
- Alarm installation as part of a renovation or extension
Not suitable for
- Commercial fire alarm systems requiring a full BS 5839-1 design, which is a more extensive specialist system than domestic alarm installation
