TROUBLESHOOTING CHART

Symptom Solution

1. No output at speakers. 1. Check for audio on the Red/Brown pair of the V-1101A while paging.

(a) If audio is present: Verify proper audio and power wiring to speakers. Try

connecting a speaker in the equipment room: Connect the Tip and Ring

leads directly to the Red/Brown pair of the V-1101A and connect the –24

Vdc and ground leads to the power supply. Test again.

(b) If no audio: Refer to Wiring Instructions and complete the power test (step

7). Correct any problems and test again. If there is still no audio, then return

to the installation Figure used and verify ALL connections. Use a meter to

verify the connections from the punchdown block to the amphenol. If there

is still no audio and you used Figure 5 Intercom Access, connect a bell or

buzzer to the V-1101A H and SIG leads. Dial the page access number. If

the bell or buzzer does not ring, then you are either not getting a page control

from the intercom, or you have connected the wrong half of the signal pair to

the V-1101A SIG lead.
