Unison® Heritage Rack Mount Contact Interface

Overview

This guide includes instruction for installation of the Unison Heritage Rack Mount Contact Interface.

The Rack Mount Contact Interface (model# UHCI-RM) provides convenient interface and integration to
external devices by sending and receiving contact closures. Up to eight switch input and relay output
connections are provided. Closures are configurable for either maintained or momentary operation.

Product Specification

• Dry contact inputs with no voltage applied.

• Dry contact outputs consist of Normally-Open (NO) 2 pole contact closu

1 amp at 28 Vdc, .5A at 120 VAC.

• Relay outputs are capable of switching resistive or inductive loads.

• Inputs and outputs are configurable in the Paradigm configuration using LightDesigner software.

• Contact inputs support up to 1,000 feet (305m) of 16 AWG (1.5mm

common.

LinkPower® (LinkConnect) control net­work utilizes low voltage Class II wire.
Wiring is topology free, polarity independent with a
maximum total system length of 1,640 feet (500m).

Required when wiring is not installed in grounded
metal conduit.

Two wires are required per switch (switch in or
switch out and common). Supports up to 1,000 feet

(305m) of 16 AWG (1.5mm

Step 1: Terminate LinkPower.

a: Strip 7/16” (11mm) from the ends of each LinkPower wire (typically black and white

twisted pair).
b: Using a jewelers screwdriver, open the ULP+ and ULP- terminals.
c: Insert the (typically white) wire from the pair into the ULP+ terminal.
d: Insert the (typically black) wire from the pair into the ULP- terminal.

Note:

LinkPower is topology free and polarity independent. You can install your LinkPower
wiring in any combination of bus, star, loop, or home-run. If more than one pair of
LinkPower wires are to be terminated be sure to label each pair individually. Each ULP
terminal can accept up to two conductors per terminal.

e: Tighten each terminal screw firmly to secure the wires in place.

Step 2: Terminate Auxiliary power (24 Vdc) wiring.

a: Strip 7/16” (11mm) from the ends of each Auxiliary power wire (typically a 16 AWG

black and red twisted pair).
b: Using a jewelers screwdriver, open the +24 VDC and Common terminals.

c: Insert the (typically red) wire from the pair into the+ 24 VDC terminal.
d: Insert the (typically black) wire from the pair into the Common terminal.
e: Tighten the terminal screw to secure the wire(s) in place.
