Nabco Multi-Module
To The Installer
The purpose of this manual is to familiarize the installer with the proper installation and operation of this module.
It is essential that this equipment be properly installed and operational before the door is used by the public. It is
the installer’s responsibility to inspect the operation of the entrance system to be sure it complies with any appli-
cable standards. In the United States, ANSI Standard 156.10 may be applicable for this type of door. Other local
standards or codes may apply.
Overview .
The Multi-Module is a programmable relay module that can be used for many applications. Very user friendly, the
module provides a single mode select push button to select the different modes of operation. (No dip switches)
Modes of Operation
Mode 1 - Electric Strike Sequencer
Typical momentary timed operation. Used for interfacing electric locks with automatic door operators. Refer to
diagram labeled “Mode 1 - Electric Strike Sequence Diagram” on page 7 & 8.
In this mode, the Multi-Module can also be used as a fully functional bi-directional door sequencer, no need to
use a second relay. Refer to diagram labeled “Mode 1 - Bi-directional Door Sequencer Diagram” on page 9 & 10.
Mode 2 - Apartment or access control
Used to interface automatic door operators directly to apartment interphone panels. Isolates interphone panel
voltages from automatic door operator. Also can be used to interface with access control systems that have timed
lock functions Refer to diagram labeled: “Mode 2 - Apartment or Access Control Diagram” on page 11 & 12.
Mode 3 - Ratchet or latching operation
Push button activates strike relay for the timed period then latches operator relay 2 indefinitely, until switch is acti-
vated a second time. Refer to diagram labeled: “Mode 3 - Ratchet or Latching Operation Diagram” on page 13.
Mode 4 - Smoke Evacuation
For wiring a door operator to a fire alarm panel for smoke evacuation purposes. In this mode the strike relay will
energize momentarily, the operator relay will stay energized for as long as the input is maintained. Refer to dia-
gram labeled: “Mode 4 - Smoke Evacuation Diagram” on page 14 & 15.
Mode 5 - Acugard Lock-out relay
Sensor inhibit, inhibiting of a door mounted sensor preventing sensor from acting like a motion sensor.
Sensor only active once push button has been activated Refer to diagram labeled: “Mode 5 - Acugard
Lock-out Relay Diagram” on page 16 & 17.
Mode 6 - Washroom control relay
Single occupant barrier free washroom control. Allows the door to be electronically locked from the inside while
removing the exterior button from the circuit. Door position switch or interior push button resets system. Installer
should recommend that a “store room” function passage set be used. Handle always locked from the exterior,
and free on the interior. Refer to diagram labeled: “Mode 6 - Washroom Control Relay Diagram” on page 18 & 19.
