Large Systems (analogue addressable)
For larger buildings, with anything from four to 250 zones, pin-pointing the exact location of a fire is paramount and requires more advanced technology: analogue addressable fire detection systems.
This type of system is wired in a loop; the same cable passes through the entire building and each zone is programmed, with individual fire detectors each having their own number (address) and text allocated. A typical loop can take up to 126 devices, all of which are continuously tested by the control panel.
Helping to reduce FALSE ALARMS
If part of the loop wiring becomes damaged, that particular section will be shut down whilst the rest of the system continues to operate, so allowing the fault to be repaired. In the event of a fire or fault, the control panel provides text descriptions of the condition detected.
We also install wire-free radio based fire systems, which are ideal for listed buildings where cabling would be unsightly or difficult to hide. The technology is more expensive, but installation is quicker and there are further cost savings to be gained in maintenance and servicing costs.
