Fire Alarm Installation in London
The installation of fire alarm systems in the UK is governed by BS5389, where BS signifies British Standards and 5389 denotes the specific standard concerning fire safety equipment. According to this standard, smoke detectors are designed to detect smoke through either the heat of smoke particles or specialized smoke-specific indicators. This detection mechanism serves the purpose of triggering an alarm before the smoke reaches a density that would react with an open fire’s flame.
Adhering to the BS5389 regulation when performing a fire alarm installation entails precise placement and height considerations for smoke detectors, adherence to electrical wiring specifications for these detectors, and provisions for incorporating battery backup systems.

- L1 fire alarm systems are smoke detectors which detect smoke from a fire and sound the alarm.

- L4 smoke alarms are smoke detectors which only detect smoke from a fire and do not warn of any other kind of danger.
- Finally, L5 smoke alarms are smoke detectors that also detect heat and sound the alarm if smoke is present and there is a high level of heat.
Who Needs a Fire Alarm?
As per BS5839 regulations, fire alarms are a mandatory requirement for all rented properties. These fire alarms offer varying levels of coverage, with the fundamental minimum standard being hardwired mains interlinked alarms in the hallway, lounge, and kitchen. This coverage is commonly referred to as Grade D, LD 3.
Landlords have the option to enhance coverage by opting for a Grade LD 2 system. This entails the installation of hardwired mains interlinked smoke detectors in every room, excluding kitchens (where a heat alarm is required), and toilets. The smoke detectors should be positioned at a minimum height of 1m above the ground and installed on an exterior wall.
Heat detectors are required as part of smoke alarm systems in kitchen.
