Testing
Testing should only be undertaken by a qualified electrical engineer.
A suitably rated tester is required to verify presence/absence of mains electrical power on the
contactor terminals and any socket outlets or load equipment connected to the contactor output.
During the tests hazardous voltages will be present inside the contactor box and on controlled outlet
sockets or load equipment. Use appropriately insulated test equipment and keep unauthorised
personnel clear of the test area.
During testing power will be fed to any connected equipment. Ensure that this will not present a
hazard.
Turn on the ICS power switch and confirm the ICS is powered (lights on front panel or power switch).
Set the ICS ready for arming, with all monitored doors closed. Set the ICS keyswitch to ‘Enable’. The
‘Arm’ button should be illuminated blue.
Turn on the mains supply to the contactor box and confirm that voltage is present on the input line
terminals of the contactors.
Verify that the contactors are not energised and that there is no voltage on the output (load)
terminals of the contactors, or on any outlet sockets or at the controlled device (e.g. laser) supply
input terminals.
Press the ‘Arm Laser’ button on the ICS and confirm the ‘Laser Armed’ indication is lit.
Verify that both contactors are energised and that the correct voltage is present on all controlled
socket outlets and/or load equipment supply terminals.
Disarm the ICS by opening a controlled door or set the keyswitch to ‘Disable’ and confirm that both
contactors are de-energised and there is no voltage on the controlled sockets or equipment.
Isolate the electrical supply to the contactor box. Remove the wire from terminal 21 of one of the
contactors. Set the ICS keyswitch to ‘Enable’, press the ‘Arm Laser’ button and confirm that the ICS
does not arm, the ‘Arm Laser’ button does not light, and the contactors are not energised.
Replace the wire to terminal 21 of the first contactor, remove the wire from terminal 21 of the other
contactor and repeat the test.
Refit the wire to terminal 21 of the second contactor. Repeat the test and confirm that the ICS does
arm, the ‘Laser Armed’ light is lit, and the contactors are energised.
Set the ICS keyswitch to ‘Disarm’ and turn off the ICS power switch. Fit the cover to the contactor
box and restore the supply to the contactor box.
Testing is complete.
