Product Overview
The SDC ACM-1 Access Control Module is an installer-friendly interface relay board designed to release a magnetic locking device or electric strike. It provides a lock status output and offers easy-to-use multiple wiring terminals for additional access control Request to Exit (REX) inputs.
Operation
When any REX input is activated, the relay will release the magnetic lock or electric strike. The Lock Status Output will change state, and the green LED will illuminate.
This module is compatible with any Request to Exit (REX) output, including Request-to-Exit Push Bars, Keypads, Card Readers, Motion Sensors, Push Buttons, or Key Switches.
Wiring Diagram Description
The diagram illustrates the wiring connections for the SDC ACM-1 module. Key components and connections include:
- Power Supply: A block labeled "POWER SUPPLY" with terminals for positive [+] and negative [-].
- Module Power Input: Terminals labeled "POWER" with [+] and [-] for connecting the power supply. An annotation indicates "ADD JUMPER FOR 12VDC OPERATION" pointing to a jumper block.
- REX Inputs: Two sets of terminals: "N/C REX INPUTS" and "N/O REX INPUTS". Each set has three pairs of terminals labeled COM, N/C, and N/O. A note states: "JUMPER ALL UNUSED N/C INPUTS".
- Monitor Outputs: Terminals labeled "MONITOR OUTPUTS" with COM, N/C, and N/O.
- Lock Outputs: Two options are shown: "FAIL SAFE LOCK" and "FAIL SECURE LOCK", each depicted with a coil symbol representing a lock mechanism. The "or" separator indicates these are alternative configurations.
- Access Control Outputs: Terminals labeled "N/C ACCESS CONTROL" and "N/O ACCESS CONTROL".
- Indicator: A "RELAY ACTIVE INDICATOR" labeled "D3" is shown, with an arrow pointing to it.
