sufficient capacity to hold the system up for the time defined in the system design. The battery
should be physically inspected for any deformation of the casing or any sign of leakage; if any of
these conditions exist the battery should be immediately replaced.
NOTICE: The new battery should be of the same capacity or greater (up to the maximum the system
can accommodate).
l
If the main fuse blows then the system should be checked for any reasons. The fuse should be
replaced by a fuse with the same rating. The rating is stated on the system label in the rear of the
housing.
l
The time and date onboard PCB lithium battery is only used when the system is left un-powered; in
this state that battery has a life of approximately 5 years. The battery should be visually checked
once a year and all power removed from the system to ensure that system retains the time and date.
If the system does not retain the time and date the battery should be replaced with a new Lithium
cell type CR1216.
l
All electrical connections should be checked to ensure that the insulation is in place and there is no
risk of shorting or becoming disconnected.
l
It is also recommended that any firmware update release notes be checked for any additional
updates that may improve the security of the system.
l
Check all physical mountings are intact. Any broken mountings should be replaced with the same
parts.
23.15 Maintenance Smart PSU
The system should be serviced in accordance with the service schedule that is in place. The only
replaceable parts on the Smart PSU are the mains fuse and standby battery.
It is recommended that during a service the following be checked:
l
The controller Event Log to check if any standby battery tests have failed since last service – if
standby battery tests have failed then the standby battery should be checked.
l
The standby battery should be replaced as per the servicing schedule to ensure that it has sufficient
capacity to hold the system up for the time defined in the system design. The battery should be
physically inspected for any deformation of the casing or any sign of leakage; if any of these
conditions exist the battery should be immediately replaced.
NOTICE: The new battery should be of the same capacity or greater (up to the maximum the system
can accommodate).
l
Check the LEDs on the PSU control board are in the expected state. See Smart PSU document for
LED details.
l
If the main fuse blows then the system should be checked for any reasons. The fuse should be
replaced by a fuse with the same rating. The rating is stated on the system label in the rear of the
housing.
l
All electrical connections should be checked to ensure that the insulation is in place and there is no
risk of shorting or becoming disconnected.
l
It is also recommended that any firmware update release notes be checked for any additional
updates that may improve the security of the system.
