Fire Alarm Maintenance procedure

On arranged visits to your property our engineers will carry out the following:

The system log book should be examined.  It should be ensured that any faults recorded have received appropriate attention.

When attending a customer premises, the following must be carried out:

  1. Contact site responsible person
  2. Sign in, in the required book
  3. If system is on watch take system off watch
  4. Notify required persons / departments that system is being tested and to ignore any fire signals. If system is link to a fire alarm network, notify site monitoring persons which block is being tested.
  5. Carry out required tests
  6. Notify required persons / departments that the systems tests have been completed. If system is linked to a fire alarm network, notify site monitoring persons that this block / building has been tested and is now finished
  7. Contact site responsible person and report tests finished and get the docket signed.
  8. Sign out of required book
  9. Put system back on site checking that correct signals have been received

Recommendations for periodic inspection and test of system

The following recommendations are applicable

a)      The system log book should be examined. It should be ensured that any faults recorded have received appropriate attention

b)      A visual inspection should be made to check whether structural or occupancy changes have affected the compliance of the system with recommendations of BS5839- standard for siting of manual call points, automatic fire detectors and fire alarm devices. Particular care should be taken to verify whether;

  1. All manual call points remain unobstructed and conspicuous
  2. Any new exits have been created without the provision of an adjacent manual call point
  3. Any new or relocated partitions have been erected within 500 mm of horizontally of any automatic fire detector
  4. Any storage encroaches within 300 mm of ceilings, such as to obviate compliance
  5. A clear of 500 mm is maintained below each automatic fire detector, and that the ability of the detector to receive the stimulus that it has been designed to detect has not been impeded by other means
  6. Any changes to the use or occupancy of an area makes the existing types of automatic fire detector unsuitable for detection of fire or prone to unwanted alarms
  7. Any building alterations or extensions require additional fire detection and fire alarm equipment to be installed

c)      The records of false alarm should be checked. The rate of false alarms during the previous 12

d)     The battery voltage should be measured with the mains on to check the steady state charge voltage and check it is within the manufacturers recommendations

e)      Batteries and their connections should be examined and momentarily load tested with the mains disconnected to ensure that they are in good serviceable condition and not likely to fail before the next service visit.

f)       The fire alarm functions of the CIE (Control & Indicating Equipment) should be checked by operation of at least one detector or manual call point on each circuit. An entry should be made in the logbook indicating which initiating devices have been used for these tests.

g)      The operation of the fire alarm devices should be checked

h)      All controls and visual indicators at the CIE should be checked for correct operation

i)        The operation of any facility for automatic transmission of alarm signals to an alarm receiving centre should be checked. Where more than one form of alarm signal can be transmitted (e.g. fire and fault), the correct transmission of each signal should be confirmed.

j)        All ancillary functions of the CIE should be tested

k)      All fault indicators and their circuits should be checked, where practicable, by simulation of fault conditions

l)        All printers should be tested to ensure that they operate correctly and that the characters are legible

It should be ensured that all printer consumables are sufficient in quantity or condition to ensure that the printer can be expected to operate until the time of the next service

m)    Radio systems of all types should be serviced in accordance with the manufacturers recommendations

n)      All further checks and test recommended by the manufacturer of the CIE and other components of the system should be carried out.

o)      On completion of the work, any outstanding defects must be reported to the premises manager, the system logbook should be completed and an inspection and servicing certificate should be issued.

Recommendations for inspection and test of the system over a 12 month period

The work described be carried out over the course of two or more service visits during each twelve month period.

In addition to the above mentioned work, it is recommended that the following work be carried out every year.

a)      The switch mechanism of every manual call point should be tested, either by removal of frangible element, insertion of a test key or operation of the device as it would be operated in the event of fire.

b)      All automatic fire detectors and remote indicators should be examined, as far as reasonably practicable, to ensure that they have not been damaged, painted, or otherwise adversely affected. Thereafter, every detector should be functionally tested.

c)      Every heat detector should be functionally tested by means of suitable heat source.

d)     Point smoke detectors should be functionally tested by a method that confirms that smoke can enter the detector chamber and produce a fire signal.

e)      Optical beam smoke detectors should be functionally tested by introducing signal attenuation between transmitter and receiver.

f)       Aspiration fire detection and fire alarm systems should be functionally tested by a method that confirms that smoke can enter the detector camber and produce a fire signal.

g)      Carbon monoxide fire detectors should be functionally tested by a method that confirms carbon monoxide can enter the chamber and produce a fire alarm signal.

h)      Flame detectors should be functionally tested by a method that confirms the detector will respond to a suitable frequency of radiation and produce a fire alarm signal.

i)        In fire detection systems that enable analogue values to be determined at the CIE, it should be confirmed that each analogue value is within the range specified by the manufacturer. These must be recorded and devices with bad values must be rectified.

j)        Multi-sensor detectors should be operated by a method confirms that confirms products combustion in the vicinity of the detector can reach the sensors and that a fire signal can be produced as appropriate.

k)      All fire alarm devices should be checked for correct operation. It should be confirmed that visual fire alarm devices are not obstructed from view and that their lenses are clean

l)        All unmonitored, permanently illuminated filament lamp indicators at CIE should be replaced

m)    Radio signal strengths in radio-linked systems to which clause 27 applies should be checked for adequacy, and results recorded

n)      A visual inspection should be made to confirm that all readily accessible cable fixings are secure and undamaged

o)      The cause and effect program should be checked to establish as being correct by activating at least one cause and observing the operation of effects.

p)      The standby power supply capacity should be checked to establish it remains suitable for continued service

q)      All further annual checks and tests recommended by manufacturer of the CIE and other components of the system should be carried out.
