1. Introduction

The Legrand AC1023 Intercom/Unity Relay Module
(see Figure 1) provides the relay interface between
the SCI Intercom Module (IC5001) or Unity Integration
Module (HA6001) and a third party electronic door
strike. This relay module supports a remote door
release capability as part of an SCI Intercom or Unity
system. It supports a 12 VDC door strike and is
powered by an appropriate third party AC to DC power
supply.

2. Description

• Provides one 2.5mm DIN jack (or 2-pin cage connector labeled “POWER”) for connection to a third party 12 VDC

AC to DC power adapter.

• Provides one 2-pin cage connector (labeled “CTRL”) for connection to the SCI or Unity Integration Module.

• Provides one 2-pin cage connector (labeled “OUT”) for connection (up to 2A) to the electronic door strike.

• Provides one 4-pin cage connector (labeled “DRY CONTACT”) that supports a Normally Closed (plus Common)

and Normally Open (plus Common) connections for use when a dry contact is used to initiate the door strike
(rather than the SCI or Unity system).

3. Installation

Installation of the Legrand AC1023 and related components is best accomplished at multiple times during new
construction, at “Rough-in” before the drywall is installed, and at “Trim-out” after the drywall is installed and painted
(see Figure 2).

any single component. If you are unsure of any of the following installation procedures contact Legrand
