The UNI•COM is capable of reporting 198 points or 56 zones when used with the
Unimode 200.
The UNI•COM may be mounted in the Unimode 200 control panel or remotely in an
ADT-ABS8RF or ADT-UBS1F enclosure up to 6000 feet away from the control
panel. All power must be removed from the control panel before making any
connections to prevent circuit damage. The EIA-485 serial interface is connected
between the control panel and UNI•COM using twisted, shielded pair wire. Power
should be wired from the control panel's 24 VDC (nominal) filtered, non-resettable
output to TB1 on the UNI•COM if mounted remotely.
UNI•COM mounting in Unimode 200
Remove all power from the Unimode 200 by disconnecting AC and batteries. Install the supplied standoffs (three nylon
and one aluminum standoff) in the appropriate holes located on the right side of the Unimode 200 main circuit board as
illustrated in Figure D-2. Position J10 located on the back of the UNI•COM over connector J16 which is located center
right on the main Unimode 200 circuit board, and carefully connect. Secure the UNI•COM to the aluminum standoff
with the screw provided.
The EIA-485 circuit and 24 VDC power are provided directly from connector J16 of the Unimode 200. Note: A 120 ohm
EOL resistor is not required on the UNI•COM EIA-485 terminals when it is installed inside the Unimode 200 cabinet.
The EOL resistor is required at the last device on the EIA-485 line external to the Unimode 200 panel.
