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).

4. OPTIONAL: If being connected to a dry contact for control, connect the 16/2 cable from the Normally Open or Normally Closed dry contact to the cage connector pins labeled “DRY CONTACT” on the AC1023 module.

5. After all connections have been made, plug the 12VDC power supply cable into the 2.5mm DIN power jack (or connect the cable to the “POWER” cage connector pins on the AC1023 module and plug the power supply into an AC outlet.

NOTE: All AC powered devices in a Unity system should be powered up at the same time (i.e. use a common power strip for the individual AC adapters).

6. Verify door strike functionality.
