Domestic Fire Protection
Home Smoke and Fire Detection in Surrey and London

Installing smoke, heat and carbon monoxide detectors is just the first step of keeping you and your family protected.

To ensure your detectors always work when you need it most, each one is linked into your Rohallion intruder alarm panel where it’s constantly monitored.

Fire Detection Methods

Optical smoke alarm sensor, (commonly called a smoke alarm) works using the light scatter principle. The alarm contains a pulsed Infrared LED which pulses a beam of light into the sensor chamber every few seconds to check for smoke particles.


Heat detectors are designed to respond when the thermal energy of a fire increases in temperature. The heat sensitive element of the sensors element regulates the rate flow of heat into the element to give a thermal lag to prevent false alarms.

Carbon Monoxide

The potential dangers of carbon monoxide are greatest when you’re asleep. Every home with a fuel-burning appliance/heater, attached garage or fireplace should have a carbon monoxide alarm

All fire detectors are always on, monitoring around the clock and ready to alert you to the dangers with a loud internal sounder, external sounder and external flashing strobe should there be a problem.
