Custom Electronics AOV Single Zone - Manual (Page 6)

19. Commissioning
1. When all parts of the system have been installed final connecting
and testing can be started.
2. It is recommended that all parts of the system to be wired into the
control panel are tested separately and independently before
connecting into the control panel. Any parts not working correctly
must be rectified before proceeding.
(The SLA batteries to be used in the control unit can be used to test
actuators for forward and reverse action before connecting into
control panel. Other volt free items can be checked with a multi-
meter before final connection)
3. The mains input should be connected first into the power supply
mains terminal block. After checking that any bare cable ends are
clear of circuit boards the unit can be switched on. When switched
on the relays on both main PC boards will “click” and LEDs will
light up:
Amber on power supply PCB
Green and amber on AOV PCB
Green and amber on lid cards
4. After 40 to 50 seconds when the AOV timers have reset there
should be:
one green LED illuminated on AOV PCB
one amber LED illuminated on power PCB
Green and amber illuminated on left lid card
5. Now connect the SLA batteries 2 x 12volt in series to make a
24volt set. Then connect the battery set into the battery terminals
on the PSU PCB taking particular care to get the correct polarity.
6. After connecting the batteries there should be only the green LED
illuminated on the left lid card.
7. At this point the rest of the system components should be added
one at a time testing the performance as each part is connected. If
there is a problem in the wiring of one of the parts it will show up
when tested and can be rectified immediately.
8. Once all of the parts are connected successfully the system as a
whole can be tested:
Check that each smoke detector operates correctly and operates the
correct actuator(s).
Check that each call point operates correctly and operates the
correct actuator(s)
Check that the “Firemans switch” operates correctly.
Check that each actuator operates as required.
9. Once the testing has been satisfactorily completed the system
should be tested again with the mains supply to the unit switched
off. The system should still operate as before if the batteries are in
new condition. If not then switch on mains refit the lid and leave
the unit for 24 hours for the batteries to charge and then retest.
20. Maintenance
The AOV control panels do not require any specific maintenance other
than replacement of the Sealed Lead Acid batteries that generally have a
4-5 year life from new.
These batteries should be performance checked annually as a minimum
and tested on a regular basis for operation by switching off the mains to
the unit. If the batteries are in good condition they should be able to
operate the system with the mains off.
Any problem should be rectified immediately
The system should be checked regularly for continued performance by
testing each of the connected parts.
