What happens on the day
Our fire and smoke alarm work in Wandsworth begins with checking where detection is needed. 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.

Photos of our work
Does Bello Electrics Ltd fit smoke alarms in Wandsworth?
We fit smoke alarms and test fire alarm systems in Wandsworth. Our alarm installations also include heat detection in kitchens and carbon monoxide detectors near appliances that burn fuel.
What happens during the alarm installation after booking?
We assess the detector positions before mounting the units and connecting their electricity with the supply off. We then check the linked warnings, test the backup power and explain the testing buttons.
Can kitchen detection avoid reacting to cooking smoke?
A heat detector responds to temperature changes instead of smoke particles from cooking. We fit this type of alarm in cooking areas to avoid ordinary cooking smoke and steam triggering smoke detection.
Can alarms warn people on another floor without a linking cable?
Compatible mains powered detectors can carry the warning between floors through radio signals. This connection avoids installing a separate linking wire through decorated ceilings.
What alarm details will come with the installation?
We give you a written record naming the installed detector types and their positions. It includes the replacement dates set by the manufacturer and identifies the wiring circuit powering the units.
