Fire detection systems in care homes are governed by BS 5839-1. A Category L system (life protection) is required -- typically Category L1, which provides full coverage of all areas including roof voids and floor voids where relevant. Category P (property protection) systems alone are insufficient for a sleeping-risk premises.
Grade D systems (mains-powered domestic smoke alarms with battery backup) are designed for houses. They do not meet the requirements for a care home, which needs a Grade A addressable system -- one where each detector is individually identified on a control panel, enabling the location of a fire to be pinpointed immediately.
Optical smoke detectors are best for slow-smouldering fires (most common in bedrooms). Heat detectors are appropriate for kitchens where smoke is a normal feature of cooking. Multi-sensor detectors combine optical and heat sensing for greater reliability. Carbon monoxide detectors are required separately where gas or oil appliances are present.
Weekly tests of at least one detector (rotated so all are tested over time) must be logged. An annual service by a competent fire alarm engineer is required, checking all detectors, the control panel, call points and any interlinked systems (door holders, suppression). The service certificate must be retained.
CareHomeDesk gives you compliance checklists, maintenance logs, and contractor management tools built around exactly this kind of knowledge.
