Whole House Alarm Systems

For new builds or house extensions, mains-powered and interlinked smoke detectors (Grade D units) are compulsory according to BS 5839-6. For existing properties which do not fall under building regs, you can install battery operated alarm systems that do not require cabling. This saves time, incurs less cost and does not affect the aesthetics of your interior. Battery operated units are easy to set up and use radio frequency (wireless technology) to communicate and interlink.

Essentially whole house systems are designed to ensure that if one alarm unit detects a potential fire or hazard then the whole system is alerted and all sounders within it alarm. This creates a full 'warning system' to the occupants of the building and gives more time for evacuation/investigation.
