Fire Alarm and Detection Systems are designed to specific categories aimed to protect life and/or property. All our work is carried out in accordance with BS5839-1:2013 with certificates issued on completion. We are accredited members of BAFE an independent certification body that ensures companies that install and maintain fire alarm systems and are trained in the specific skills required and working to appropriate standards. We are also a member of the FIA and the UK Fire Association. We offer one free staff training session following a new installation and ongoing customer support with a 24 hour call out service for any emergencies that may occur.

Types of Fire Alarm Systems

All Fire Alarm Systems essentially operate on the same principle. If a detector detects smoke or heat or someone operates a break glass unit (manual break point), then alarm sounders operate to warn others in the building that there may be a fire and to evacuate. It may also incorporate remote signalling equipment which would alert the fire brigade via a central station.

Fire Alarm Systems can be broken down into 3 types:

  • Conventional
  • Addressable
  • Wireless

Conventional Fire Alarm Systems

In a Conventional Fire Alarm System, a number of call points and detectors are wired to the Fire Alarm Control Panel in Zones. A Zone is a circuit and typically one would wire a circuit per floor or fire compartment. The Fire Alarm Control Panel has a number of Zone Lamps. The reason for having Zones is to give a rough idea as to where a fire has occurred. This is important for the fire brigade and of course for the building management. The accuracy of knowing where a fire has started is controlled by the number of Zones a Control Panel has and the number of circuits that have been wired within the building. The Control Panel is wired to a minimum of two sounder circuits which could contain bells, electronic sounders or other audible devices. Each circuit has an end of line device which is used for monitoring purposes.

Addressable Fire Alarm Systems

Addressable Fire Alarm Systems are often known as Intelligent Fire Alarm Systems. Each smoke detector and manual call point has an individual address number with its own descriptive text to help the end user determine more quickly the exact area of alarm. The detectors communicate to the Control Panel via data and report whether there is a fire, fault or the detector head needs cleaning. There are several different types of Addressable Systems available which are determined by the type of protocol which they use. With the Addressable Systems, up to 127 input devices i.e.: Smoke Detectors, Call Points, Heat Detectors, Contact Monitors and other interface devices may be wired to each detection loop.

Addressable Fire Alarm Systems
Wireless Fire Alarm Systems

Wireless Fire Alarm Systems

Wireless fire alarm systems are an effective alternative to traditional wired fire alarm systems for all applications. They utilise secure, licence-free radio communications to interconnect the sensors and devices (smoke detectors, call-points, etc.) with the controllers. It is a simple concept, which provides many unique benefits and is a full analogue addressable fire detection system without the need for cable. Ideal for older buildings or linking separated buildings.
