Fire Alarms, Call points and Smoke Detectors
A Conventional fire system is the starting point for most fire system requirements, these are suitable for small offices, nursery's, small hotels, warehouses, shops & any small business.
A conventional system has detection zones, connected to these zones are a number of automatic fire detectors (AFD) such as heat or smoke detectors and manually operated break glass call points. When one of the above detectors is triggered an LED will light up on the detector and on the relevant zone back at the main control panel to identify the area of the fire.
The control panel will then operate the sounders or sounder beacons which are usually on a separate circuit.
Relay out puts
The main control panel will have a number of relay out puts to operate building interfaces such as lifts, access control. door holders, other fire alarm panels or a link to the fire brigade Control.
Control and operation of the main control panel is usually by a key or code, this restricts access to the panel to the specified users only. A range of options are available such as one man walk test (useful for weekly testing), disabling of sounders or detection zones.
A range of specialized fire detection devices are available to cover the less common requirements, including beam type detection for large open areas, flame detectors to recognize a sudden burst of heat and heat detectors which can be used in Kitchens and Boiler Rooms without causing false alarms.
All systems comply with BS5339 and Fire Extinguishers to BS5306.
