- SUPPLEMENT TO TC-M INSTRUCTIONS -
The TC-MD Intercom and Selective Door Control System is designed for communication between a central master
station and remote door stations. The TC-MD adds door release to the standard TC-M system. All information
regarding installation other than the external control functions is included in the TC-M instructions. In addition to
communication to remote locations, the Master Station can selectively release the corresponding door strike or
maglock.

IMPORTANT:
1. RY-PA must be used for each selective contact to
isolate AC voltage from the intercom circuit.
2. Extra contact connections and L are on the
external terminal block.

OPERATION:
* POWER SWITCH ON THE BACK OF THE MASTER MUST BE ON FOR SYSTEM TO BE OPERABLE.
** DOOR RELEASE BUTTON IS LOCATED BELOW THE "TRANSFER" BUTTON ON THE MASTER.
1. When a station calls in, pick up the handset and press the selector button corresponding to the lit LED.
2. Speak to the person at the remote station through the handset. The person at the remote station
speaks hands free.
3. To release the door at the calling party's location, press the "door release" button while still in
communication with the calling station. This will activate the corresponding relay as long as the button is
being held, which will activate the door release mechanism.
4. If both selective door release and a constant closure are used on a channel, the device connected to
the "constant closure" relay will be on as long as the channel is selected. The "momentary closure"
will only be active when the door release button is pressed.
5. When the conversation is completed, hang up the handset.
