21.3 Maintenance
Instructions
BS60849 requires a stiff-covered maintenance manual containing documented procedures that deal with the
maintenance and re-test in accordance with the manufacturer’s recommendations and relevant national and
international standards, and it recommends a minimum of two scheduled maintenance inspections each
year.
21.3.1 Routine
Maintenance
21.3.1.1 Daily
Attention
Each day, the VAR Router should be checked for indication of normal operation as part of the fire alarm
system routine maintenance. If there is a remote indicator panel for the VA system, this should also be
checked.
21.3.1.2
Weekly Attention
On a weekly basis, the fire detection system should be activated and the VA system checked to ensure it
operates under alarm conditions. The VAR Router should be checked for indication of normal operation and,
if there is a remote indicator panel for the VA system, this should also be checked.
21.3.1.3
Monthly Attention
If an automatically started emergency generator is used as part of the standby supply, then it should be
started up once each month by a simulation of a failure of the normal power supply. It should be allowed to
energise the fire alarm supply for a continuous period of at least 1 hour. The VAR Router should be
monitored to identify any malfunctioning caused by the use of the generator.
21.3.1.4
Quarterly Inspection and Test
The responsible person should ensure that every 3 months a competent person carries out the following
checks:
a. Entries in the log book should be checked and any necessary action taken.
b. The service life of the internal RTC back-up battery should be checked and replaced if it exceeds 5
years.
c. All fault indicators and their circuits should be checked, preferably by simulation of fault conditions. The
VAR Router should be visually inspected for signs of moisture ingress and other deterioration.
Any defect should be recorded in the log book and reported to the responsible person, and action should be
taken to correct it.
On completion of the work, a Certificate of Testing should be completed and given to the responsible person.
