The fire alarm code for Europe EN54 suite of standards relates to the design and performance of items of equipment that make up a fire detection and fire alarm system.
Each part relates to a different piece of the fire equipment, for example part 3 relates to alarm devices, part 11 to manual call points, part 4 to power supplies etc.
Some parts of the EN54 fire code standards have options with requirements. These relate to specific features that are required in certain applications but not all. For example all fire control panels and indicating equipment must be able to detect fire (with the help of appropriate input devices), such as smoke or heat detectors, must monitor certain functions (such as cables for open and short circuit faults) and must have a disablement or isolate facility so that functions or areas of cover can be switched off for maintenance or similar activities. However it is optional to have a test facility or delays to fire alarm outputs, but if such features are either provided or required in the application (e.g. to allow a local search for fire prior to calling the brigade) then those facilities must meet specified criteria.
It is therefore necessary when specifying compliance to the European fire code EN54 that the relevant part is identified and that the application standard (such as BS5839-1) is consulted to identify specific options.
For example, the UK fire brigade almost always will require zonal light
emitting indicators to be incorporated in control equipment to show
the extent of the fire event at a glance; this is an option in EN54-
The fire alarm, enabling you to get much bigger amounts of information from fire security equipments, Which is called really brilliant. In traditional techniques, initial of one device of the location gives an indicator on the user interface to stimulate the whole location, without showing the actual place / device.
