SINGLE READER EXPANSION MODULE

SINGLE READER EXPANSION MODULE INSTALLATION GUIDE A D C - A C X 1

TR- SINGLE READER EXPANSION MODULE The ADC-ACX1 Single Reader Expansion Module provides a solution for interfacing to a one Wiegand reader and door hardware. It also provides LED control and buzzer control. Two Form-C contact relay outputs may be used to control locking hardware. The two inputs provided can be used for monitoring door contacts and request to exit devices. Input circuits can be configured as unsupervised or supervised using end of line resistors. Communication to the Alarm.com Door Controller is accomplished using a 2-wire RS-485 interface. The ADC-ACX1 requires 12 to 24V DC for power.

The total cable length is limited to 2,000 feet (609 meters). Shielded cable of 24 AWG with characteristic impedance of 120 ohm is specified for the 2-wire RS- 485 interface. If the ADC-AX1 is the last device on the communication bus, jumper J4 must be installed. ADC-ACX1 Installation Guide 3

RS-485 Wiring using the ADC-ACC1-17 Door Controller UP TO EIGHT TOTAL EXPANSION MODULES MAY BE WIRED. THE LAST EXPANSION MODULE ON THE BUS MUST HAVE JUMPER J5 INSTALLED FOR ADC-ACX2 MODULES AND J4 INSTALLED FOR ADC-ACX1 MODULES.

Wire each expansion module to the next module instead of wiring directly back to the controller. 4 Single Reader Expansion Module

Addressing Install the jumpers on the ADC-ACX1 expansion module according to the "Jumpers/Switches ON" column in the Access Control Devices table on the Alarm.com Dealer Website. These jumpers are also displayed in the "Add Expansion Module" installation wizard. If these jumpers are not installed according to the website, the device and its connected reader and door hardware will not function properly with Alarm.com. Reader Wiring The reader port supports a one Wiegand reader. Readers with power requirements different from the input voltage used for the ADC-ACX1 board must be powered separately.22 AWG minimum recommended for readers. Typical Reader Wiring 1 TB4 BZR LED D1/CLK D0/DAT VO The input power is passed through to the reader terminal strip and is available for powering a reader. Care must be taken to ensure that the input voltage is within the voltage range of the reader. The reader power output terminal, TB4-6 (VO), is not current limited. ADC-ACX1 Installation Guide 5

Relay Wiring Two 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 (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 are 5 A for relay K1 and 1 A for relay K2. 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.

Input Wiring There are 8 inputs that are typically used to monitor door position or request to exit 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. * Grounded and foreign voltage states are not a requirement of UL 294 and therefore not verified by UL. 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.
