Appendix B: System Maintenance
Inspections
The system should be inspected at least once per year. At each inspection:
Check the control unit for obvious signs of damage to the case or its lid.
Check the action of the tamper switch.
Check, and if necessary, replace the standby battery.
Check keypads and other devices for obvious signs of damage.
Test the action of all buttons on all keypads.
Clean the surface and display of each keypad using a clean, soft, dry cloth. Do not
use water, solvents or any proprietary cleaning materials.
Where applicable, check cabling for signs of damage or wear.
Monitor the signal strength and battery condition of all detectors, radio keypads,
remote controls, radio HUDs and radio sounders. Test each device. Replace
batteries as recommended by the device instructions.
Gently clean the lenses of any PIRs with a clean, soft dry cloth. Do not use water,
solvents or any proprietary cleaning materials.
Walk test all detectors.
Test any external sounders and strobes.
Note: You can use Test – Locate Bus Device to find the location of a bus device (the
device emits a continuous sound).
Replacing or removing devices
Note: Make sure that you remove all power from the system before physically
disconnecting any device.
Removing a plug-on module
If you wish to remove a plug-on module, ensure that you disable communications first in
the appropriate menus (such as in the Communications – ARC Reporting,
Communications – Speech Dialler and Communications – SMS menus). Otherwise, the
control unit will continually report a communications failure.
Removing a bus device permanently
Before physically disconnecting the device, enter the Installer menu, and use the
appropriate Delete option. For example, to delete a keypad, use Devices/Detectors –
Wired Keypads – Delete Keypad. This ensures that the system does not report a missing
device and the device's internal address is erased (allowing it to be used on another
system).
