Output Control Expansion Module (ADC-AC-X300) - 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-X300). For instructions on how to set up a broader access system, see HID Aero Series Smarter Access Control - Quick Start Guide.
The ADC-AC-X300 expansion module provides a solution for controlling 12 additional outputs. Three dedicated inputs are provided for Tamper, AC Fail, and Battery Fail. Two inputs are provided and can be configured as unsupervised or supervised using end-of-line resistors. Communication to the X1100 Door Controller is accomplished using a 2-wire RS-485 interface. The ADC-AC-X300 requires 12-24 VDC for power. See the following figure for component location.

Communication Wiring
The ADC-AC-X300 communicates to an X1100 Door Controller using a 2-wire RS-485 interface. The ADC-AC-X300 allows for multi-drop communication on a bus of up to 4,000 feet (1,219 m). Use twisted pair (minimum 24 AWG) with drain wire and shield for communication. If the ADC-AC-X300 is the last device on the communication bus, jumper J1 must be set to IN.
RS-485 Wiring using the ADC-AC-X1100 Door Controller
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.
Install jumpers according to the selected configuration
- If there are additional downstream expansion modules, set jumper to OUT
- If this is the last device on the communication bus, set jumper to IN
Relay Wiring
Twelve Form-C contact relays are provided for controlling door lock mechanisms. 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 (failsafe), 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.
Note: 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 further away.
Use sufficiently large gauge wires for the load current to avoid voltage loss.
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
Input Wiring
There are two inputs that can be used to monitor door position, request-to-exit, or alarm contact devices. Input circuits can be configured as Unsupervised (2 states): reporting as open or closed contact, or Supervised (6 states): reporting as open or closed contact, open circuit, shorted circuit, grounded circuit, or foreign voltage.
A supervised input circuit requires adding two resistors with value of 1k ohm, 1% to the circuit to facilitate proper reporting and should be located as close to the sensor as possible.
The input circuit wiring configurations shown are supported but may not be typical.
22 AWG minimum required for input wiring. 18 AWG recommended if wiring request-to-exit devices in series with locking hardware.
Note: Either the top or bottom 12-24 V terminals can be used to power the board.
