Testing Your Consoles

You can test the lights and ringer on your SLAC and the
lights on your Selector Console. On the SLAC, the Test
switch is located on the left side. It has two positions, T
and P (the P position is inoperative). On the Selector
Console, the Test button is the rightmost button in the
bottom row with the Group Select buttons. Notify your
System Administrator if any light or ringer does not operate.
Testing the SLAC
1. Push the Test switch to the T position and hold it
there during the test.
The red and green lights alternately turn on and
off, and the ringer sounds.
2. Release the Test switch to its normal mid-position.
Testing the Selector Console

• The red lights cycle on and off sequentially.
2. Press the Test button again; the individual lights can be
tested by pressing the adjacent buttons.
3. Press the Test button a third time to end the test.
