Smoke & Fire Alarm Systems

Smoke and fire detection for homes and commercial sites brings together standalone photoelectric smoke detectors and heat alarms with ten-year sealed batteries from Mercury, some with a hush button to silence false triggers. ESP supplies wired alarm panels, a long-range beam detector and detectors with sounder and strobe, alongside a Mercury fire blanket for the kitchen. Mix standalone units with panelled detection to match each building.

Smoke and Fire Alarm Systems for Homes and Larger Sites

Fire detection works best when each part suits the building it protects, and this range brings the main options together. Standalone photoelectric smoke detectors and heat alarms cover individual rooms, with a ten-year sealed battery so there is no annual cell to change across the life of the unit. A hush button lets you silence a nuisance trigger from cooking or steam without taking the alarm out of service, which keeps it working day to day rather than being switched off in frustration.

For sites that need wired detection, the range includes two-wire and addressable fire alarm panels, from compact conventional units up to multi-zone addressable panels for larger or split buildings. Two-wire detectors with built-in sounder and strobe combine smoke and heat sensing with audible and visual warning on a single pair of cables, which simplifies the wiring run. A long-range beam detector covers wide open spaces such as halls and warehouses, where point detectors would be slow to react. Battery expansion boxes and a network interface card let bigger systems grow, linking panels so detection across several areas reports back in one place.

A fire blanket rounds out the kit for the kitchen, giving a quick way to smother a pan fire before it spreads. Choosing between standalone alarms and panelled detection comes down to the size and layout of the property: a single home is well served by sealed-battery units in the key rooms, while a workplace or multi-room building benefits from a panel with detectors wired back to it. Mix the two where it helps, using local alarms alongside a central panel. Free UK delivery over £99, with worldwide shipping available.

Frequently Asked Questions

What is the difference between a smoke detector and a heat alarm?
A photoelectric smoke detector senses the smoke particles from a smouldering or flaming fire, making it suited to living rooms, hallways and bedrooms. A heat alarm instead reacts to a rapid rise in temperature, so it works well in kitchens and garages where cooking fumes or dust would set off a smoke unit too often.

Do the sealed-battery alarms ever need a battery change?
The standalone smoke detectors and heat alarms here use a ten-year sealed battery, so there is no cell to replace during the working life of the unit. You simply test it regularly using the button and replace the whole alarm once it reaches the end of its life.

What does the hush button do?
The hush button lets you temporarily quieten an alarm that has gone off from steam or cooking, without disabling it. After a short period it returns to full sensitivity on its own, which means people are far less likely to remove the battery or take the unit down.

When should I choose a wired panel instead of standalone alarms?
Standalone sealed-battery alarms suit most homes, fitted in the key rooms. A wired fire alarm panel makes more sense in a workplace or a larger, multi-room building, where detectors are wired back to one point and the choice runs from compact conventional units up to multi-zone addressable panels.

Can I add more capacity to a panel later?
Yes. The range includes battery expansion boxes and a network interface card, so a larger system can grow over time and link panels together. This lets detection across several areas report back in one place rather than being managed separately.
