Component Module*  
If a DAK-2S is not available, install components as shown below.  
Capacitor: 25V, 15-33ufd Non-polarized  
Diode: 1N4148  
To 1 of C-D and  
WHITE wire of RY-AC  
To 1 of C-ML/A  
MODIFICATION INSTRUCTIONS:  
C-ML/A with Door Release contact Modied to Normally Closed (for Magnetic Lock)  
C-ML/A Rear View with PC board removed.  
Magnetic locks require Normally  
Closed contacts, keeping power  
applied to the magnet to keep the door  
locked, and breaking power to release  
the door. These instructions explain  
how to change the contact in the  
C-ML/A to Normally Closed.  
1. Remove back chassis of C-ML/A  
and move the PC-754 board aside.  
Black door release switch will be  
visible.  
2. On the switch, move* the wire from  
the NO contact (middle position) to  
the NC contact (top position).  
*Desoldering and resoldering is  
required.  
3. This modication will change the  
door release button’s function to  
Normally Closed, to be used with  
magnetic lock device.

INSTALLATION TIPS:  
1. Use shielded wire for the communication path, and ground one end of the shield to an earth ground.  
2. Run intercom wire at least 20” away from AC wiring, uorescent lights or dimmer switches.  
3. Keep intercom cable away from alarm, data, phone, video cables, and any other potential source of  
interference.  
4. Door release wires must be in a separately jacketed cable from the intercom wires. Use two separate  
cables; one for audio and one for door release.  
5. When installing a second master station, wire must be run from the rst master station, not from the  
door station. See diagram on page 2.  
6. Do not install the master station near light switches, dimmer switches, or other devices that may cause  
interference with the intercom system.  
7. Do not install the master station on the opposite wall from the door station. If the units are too close,  
acoustical feedback may result.  
TROUBLESHOOTING GUIDE:  
PROBLEM  
POSSIBLE CAUSE  
SOLUTION  
When door calls in, it shorts the #1 terminal to the E terminal.  
If the DAK-2S is installed backwards the chime from the  
door call-in will not be heard. Install the DAK-2S component  
module with the bare wire under the 1 terminal, and the door  
station 1 wired to the colored wired end of the DAK-2S.  
No call in from door to master, but  
communication works ne.  
Reversed DAK-2S component module.  
When the talk button is pressed, the other  
master rings.  
Missing or reversed DAK-2S  
component module.  
Install the DAK-2S component module as described above  
and shown on the dual master instructions.  
If both C-ML/A’s share the same power supply, a ground loop  
feedback will occur when the talk button is pushed. Install a  
separate power source for each master.  
When the talk buton is pressed, feedback is  
heard at both masters.  
Common power supply.  
Terminals 1 and - crossed  
+/- are on left column, E/1 are on right column. If swapped,  
unit will appear dead. Verify that 1 from the door station is  
connected to 1, and negative of power supply is connected to -.  
Unit appears dead; No functionality  
Take batteries out of the master station. Both power sources  
cannot be used simultaneously.  
Power supply and batteries both  
installed.  
System squeals and batteries get hot  
Chime tone sounds weak, low frequency  
If batteries are installed, replace them. If using a power  
supply, check for 6VDC. If low, install a new SKK-620.  
Weak batteries or low voltage.  
Incorrect cable being used.  
If the resistance of the wire is too great, usually from  
exceeding distance limitations, the master may not time out as  
designed. Refer to wire specications in the instructions.  
Master stays on; does not time out.  
Voice volume is too loud or too soft.  
Remove front cover of the C-ML/A and locate volume  
potentiometer through hole at bottom of unit. Use a small  
screwdriver to adjust the volume, clockwise to increase.  
Volume control not adjusted properly.  
Standard volume level.  
There is not a separate call tone volume adjustment on the  
C-ML/A so the volume level cannot be altered. Surface mount  
component level modication would be required, which is not  
paractical  
Chime tone volume is too loud.  
Make sure the negative from the 12VDC supply for the RY-AC  
is connected to the negative of the C-ML/A master. Make sure  
the WHITE wire of the RY-AC is connected to the DAK-2S  
component module to terminal 1, not negative terminal.  
RY-AC external signaling relay not working.  
Missing or wrong connection.
