Configurations
Basic Master with Slave Unit and Access Control
These instructions are for a CV-TAC400 configured as a master device to call suites over the telephone and
allow entry through a single door when the correct telephone key is pressed. A slave CV-TAC400 allows users
entry through the door associated with the slave. Card readers in the CV-
TAC400’s allow users to use cards
or keyfobs to control entry through doors.
Hardware Connections
All hardware connections are to be made before applying power to the unit.
1. Connect the Telephone Line
A dedicated telephone line is required. TIP and RING connections are provided to allow connection to
a telephone line. Typically, TIP is green and RING is red.

2. Connect the Modem Module (Optional)
A modem module is used to connect to a remote computer for programming the CV-TAC400. The
remote computer must have a modem connection, and calls the CV-TAC400.
When a modem connection is used, the CV-TAC400 must be configured to use a shared phone line.
The telephone line connected to the modem module may be the same telephone line used by the CV-
TAC400 to call the suites.
