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.
