The initial acceptance testing of a new system is important to assure that the system is installed and functioning properly. Maintenance, which includes periodic inspection, testing and servicing of the fire detection and alarm system, is essential to ensure performance when needed. This document provides guidance for the initial acceptance testing of the fire detection systems and for their maintenance.

Adequate fire alarm maintenance is as critical as the original decision to install them. Because fire detection and alarm systems aren't employed on a regular basis, their condition of readiness isn't really clear. However, when these systems are called on to operate, there is usually an unexpected emergency taking place and therefore, it is vital that the system works correctly first time. There is no time to perform maintenance or a fire alarm repair during the emergency.

Addressing false alarm problems also forms an element of maintenance programmes as they not only waste fire brigade time, but also significantly affect the effective working time of UK industry and service organisations e.g. hospitals. They also reduce the confidence of building occupiers on the importance of fire alarm signals.

Fire alarm servicing is required in accordance with BS5939 section 6: 44

Fault Monitoring 

One of many improvements when discussing today’s fire detection and fire alarm system has been the ability to for the system to automatically indicate if there is a fault with the system. Whether it is a power fault, an open or short circuit on the detection or sounder circuits, the system can detect the fault and raise an audible and visual alarm allowing the user to take the appropriate action to rectify the fault.  However, it is important that the system is tested on a regular basis to ensure that the system is fully operational and a major fault has not occurred and gone unnoticed.

Regular testing has benefits

Ensuring regular testing of the fire alarm provides the occupants with the opportunity to become familiar with the sound produced by the system. Some systems have a two stage operation an “Alert” and “Evacuation”. The two stages will have different tones, such as constant or pulsing. The two tones need to be activated during the test, to make sure the occupants are familiar with both signals and are aware of their meaning.
