Wiring diagram of external signaling in conjunction with the C-123L/A or C-123LW. This can be used to trigger a bell, buzzer, sounder or anything that requires a contact closure when a call is placed from the door station.

Solution

The post External Signaling using the C-123L/A or C-123LW appeared first on Aiphone.

In a dual–master station system, a loud feedback sound is heard at both master stations. 

This can be caused by a common power supply and/or missing DAK-2S. If both C-ML/A master stations share the same power supply, a ground loop feedback will occur when the talk button is pushed. Install separate SKK-620C power supplies or install batteries for each master station. The DAK-2S “Dual Master Component Modules” must also be installed per the wiring diagram below: 

Communication timeout issues 

If the resistance of the wire is too large, usually from exceeding distance limitations, the master station may not time out as designed.

22AWG = 245′ 

18AWG = 490′ 

Communication volume is too loud or too soft 

It’s possible the volume control is not adjusted properly. Remove the front cover of the C-ML/A and locate the volume potentiometer through a hole located at the bottom of the station. Use a small screwdriver to adjust the volume; clockwise to increase, and counterclockwise to decrease. Do not turn the potentiometer too hard in either direction or damage may occur.

Upon power up, the C-ML/A maser station squeals and the batteries seem to overheat. 

Cause 

Power supply and batteries are both installed. 

Solution 

Take batteries out of the C-ML/A master station if powered with an SKK-620C power supply. Both power sources cannot be used simultaneously. 

Per the C-123 instruction manual:

Adding another C-ML/A to an existing or new system.

Difficulty Level

2 – Easy/moderate – Component connection to external points.

Components Required

1. DAK-2S: Dual master adapter kit
2. Power: Each master requires its own power supply or 4 “C” sized batteries.

Instructions

1. Install components as shown on the diagram.
2. Only one master can be used at a time. A squelch tone will be heard if both master stations are on and the TALK button is pressed at either one.
3. Sub station will call both masters simultaneously and either master can answer the calling station.
