A conventional fire alarm system is a straightforward, cost-effective way to protect smaller premises. Detectors and call points are wired into a control panel in zones, and when one operates the panel shows which zone the alarm has come from and sounds the building’s alarm. It is a proven, reliable approach that suits shops, small offices, restaurants and similar buildings where a simple system meets the need. MEP designs, supplies and installs conventional fire alarm systems across the UK.
In a conventional system the building is divided into zones, and all the detectors and call points in each zone share a circuit back to the panel. When a device activates, the panel indicates the zone it is in, giving a general location rather than the exact device. This keeps the system simple and economical. For a small building with a handful of rooms or areas, knowing the zone is usually enough to locate a fire quickly, which is why conventional systems remain popular for smaller premises.
Conventional alarms are best suited to smaller, simpler buildings where the number of zones is manageable and the lower cost is attractive. In larger or more complex buildings, where pinpointing the exact device saves valuable time, an addressable system is usually the better choice. We assess the size and layout of your premises and the level of information you need, then design a system, conventional or addressable, that meets BS 5839 and suits the building.

A fire alarm system in which detectors and call points are wired in zones, so the panel shows which zone an alarm comes from rather than the exact device.
A conventional system identifies the zone an alarm is in. An addressable system identifies the individual device, which helps in larger buildings.
Smaller, simpler premises such as shops, small offices and restaurants, where a zoned system provides enough information at a lower cost.
Yes. It is a long-established, proven technology. The main limitation is that it locates alarms by zone rather than by individual device.
Conventional fire alarm systems are designed and installed to BS 5839, like other commercial fire alarm systems.
