Output Control Expansion Module (ADC-AC-MR16OUT) - Installation Guide

Notice: Installation and maintenance servicing for this device should only be performed by qualified personnel.

Note: This article specifically covers the installation of the Output Control Expansion Module (ADC-AC-MR16OUT). For instructions on how to set up a broader access system, see Smarter Access Control - Quick Start Guide.

The ADC-AC-MR16OUT expansion module provides a solution for controlling 16 additional outputs. Two dedicated inputs are provided for cabinet tamper and UPS fault monitoring. Communication to the Mercury Series Door Controller is accomplished using a 2-wire RS-485 interface. The ADC-AC-MR16OUT requires 12-24 VDC for power. See the following figure for component location.

Status LEDs

Power-up:

All LEDs OFF.

Initialization:

Once power is applied, initialization of the module begins.

When initialization is completed, LEDs A, B, CT, and BA are briefly sequenced ON then OFF.

Run time:

After a successful initialization, the LEDs have the following meanings:

  • A LED: Heartbeat and On-Line Status:
    • Off-line: 1 second rate, 20% ON Offline status.png 
    • On-line: 1 second rate, 80% ON Online status.png
  • A LED Error Indication: Waiting for application firmware to be downloaded: 0.1 s ON, 0.1 s OFF
  • B LED: Communication Port Status: Indicates communication activity on the communication port
    • CT: Cabinet Tamper
    • BA: Power Fault
    • LED 1 through 16: Illuminates when output relay OUT 1 (K1), OUT 2 (K2) is energized and so on.

The ADC-AC-MR16OUT accepts 12 to 24 VDC for power on TB7. Locate the power source as close to the ADC-AC-MR16OUT as possible. Make power connection with minimum of 18 AWG wires.

Communication Wiring

The ADC-AC-MR16OUT communicates to an Alarm.com Mercury Series Door Controller using a 2-wire RS-485 interface. The ADC-AC-MR16IN allows for multi-drop communication on a bus of up to 4,000 feet (1219 m). Use twisted pair (minimum 24 AWG) with drain wire and shield for communication. If the ADC-AC-MR16IN is the last device on the communication bus, jumper J1 must be installed.

Note: For ease of install, daisy chain expansion modules together. Wire each expansion module to the next module instead of wiring directly back to the controller.

Line Termination

For ADC-AC-MR16OUT modules at the end of the communication line, install jumper J1.

Note: The EOL jumper should be installed at both ends of the communication line. This typically includes the controller and last expansion module

Relay Wiring

16 Form-C contact relays are provided for controlling door lock mechanisms or other devices. Each relay has a Common pole (C), a Normally Open pole (NO), and a Normally Closed pole (NC). When momentarily delivering power to unlock the locking hardware (fail secure), the Normally Open and Common poles are used. When momentarily removing power to unlock the locking hardware (fail-safe), the Normally Closed and Common poles are used. Check with local building codes for proper egress door installation. 18 AWG minimum recommended for electric locking hardware.

The current ratings for relay K1 are 5 A @ 30 VDC for normally open (NO) contact and 3 A @ 30 VDC for normally closed (NC) contact. The current rating for relay K2 is 1 A @ 30 VDC. Load switching can cause abnormal contact wear and premature contact failure. Switching of inductive loads (strike) also causes EMI (electromagnetic interference), which may interfere with normal operation of other equipment. To minimize premature contact failure and to increase system reliability, a contact protection circuit may be used.

The following circuit is recommended. Locate the protection circuit as close to the load as possible (within 12 inches [30 cm]), as the effectiveness of the circuit will decrease if it is located far away.

Diode Selection
  • Diode current rating: 1x strike current
  • Diode breakdown voltage: 4x strike voltage
  • For 12 VDC or 24 VDC strike, diode 1N4002 (100 V/1 A) typical

Inputs for Cabinet Tamper/ Power Fault

Input CT and input BA are used for monitoring cabinet tamper and power failure with normally closed contacts. These two inputs are for contact closure monitoring only, and do not use EOL resistor(s). If these inputs are not used, install a short piece of wire at the input to indicate a safe condition.
