INSTALLATION OF VMC1DS-S/BZ & VMC1VDS-S/BZ DOOR STATIONS
1. Assemble the PCB and plastic insert and fit into the metal plate.
2. Pull the CAT5 cable through the hole in the back of the door station back box.
3. Secure the door station back box into the pre-cut cavity in the wall. Be sure the access hole is off center
and to the right. Incorrect installation of this box precludes secure attachment in Step 7. Also, should unit
be exposed to harsh weather, install the DSWS Weather Shield for protection.
4. Fit the two (2) position blue connector block onto the PCB at location TB3, grove side down. (
and VMC1VDS-BZ Video Door Stations only)
5. Fit the ten (10) position blue connector block onto the PCB at location TB1, grove side down.
6. Terminate the wires from the cable per the Door Station Terminations Chart.
7. Secure the metal plate to the back box using the screws provided.
8. Fit the trim ring in position if required. This is not required if the weather shield (DSWS) is used.
9. Clip plastic front onto back box.
NOTE: Use of the weather shield (DSWS) is recommended where the station may be exposed to weather. When fitted
with the weather shield, the unit has been designed to meet the ANSI/IEC 60529 IP31 Ingress Protection Rating.
