Section V: System Test - Whelen Engineering Company WPS-2900 Series Installation Manual

Section V: System Test...

After the installation of the WPS-2900 station has been completed, a basic system check is
recommended to confirm that the system is functioning properly. Before initiating these
tests, locate the system LED's on the main control board mounted to the cabinet door (see
"Fig. 23: System LED Diagnostic Indicators" on page 43).
NOTE: The KEYPAD ARM button enables local station operation via keypad. Once
pressed, the keypad remains active until either a) another keypad button is pressed, or b) 60
seconds have elapsed, whichever comes first. The KEYPAD ARM button must be pressed
each time a keypad button is to be pressed. Note that the CANCEL button is always enabled
and does not require Keypad Arm to be pressed.
1. Confirm that the ACTIVE light on the control board is flashing at a rate of a 1/2
second on and a 1/2 second off.
2. Press KEYPAD ARM, then the SI TEST® button on the siren front panel and check
to make sure that all the siren amplifier diagnostic LED's illuminate for 5 seconds.
These LED's are located on the front of the cabinet door.
3. After the amplifier LED's turn off, check to see if the AC, DC, PARTIAL and FULL
LED's are on.
If one of your amplifier lights did not illuminate during this test then refer to the procedure
below to troubleshoot the problem.
This procedure may be used when the Partial or Full LED's indicate a failure.
NOTE: In order for a "Full" indication to be valid, the "Partial" LED must also be on.
1. Press KEYPAD ARM, then the SI TEST® button located on the front panel of the
electronic cabinet. Each amplifier has a red LED diagnostic indicator that is visible
on the front panel (see "Fig. 24: Electronic Cabinet Front Panel (Type II)." on
page 44).
2. A SI TEST® will cause each amplifier's diagnostic indicator to turn on. If one or
more do not turn on, proceed to step 3. If all indicators turn on, the siren amplifiers
are functioning properly.
3. Open the front panel and remove the speaker driver from the amplifier that did not
light and install it onto an amplifier that did light. For example: If amplifier 1 did not
light but amplifier 2 did, install speaker 1 on amplifier 2 and speaker 2 on amplifier
1. This will indicate if the failure was with the speaker or the amplifier. For more
information on troubleshooting the system, refer to the advanced trouble shooting
manual.
