We fit the units with their electrical supply disconnected, then test the warnings and record the installation. ### How are smoke and heat alarm positions checked? We assess the hallways and passages for smoke detection before mounting any units. In cooking areas, we position heat alarms, which detect temperature changes rather than smoke particles. ### How is electricity connected to the detectors? We turn off the lighting or alarm supply before fastening detector bases and attaching their cables. The alarms run on mains electricity, with backup batteries providing another power supply. ### What makes a warning reach other rooms? We interlink compatible alarms, connecting them so one activated unit makes the others sound. The connection uses wires or radio signals between the detectors. ### How are the warning and testing controls checked? We operate every detector in turn and check the response of the connected alarms. We test the backup batteries and buttons, explain routine testing and record the fitted units and their replacement dates. ## Questions about fire and smoke alarms in Wandsworth ### Does Bello Electrics Ltd fit smoke alarms in Wandsworth?

A heat detector responds to temperature changes instead of smoke particles from cooking.

Compatible mains powered detectors can carry the warning between floors through radio signals.
