Microprocessor Controller - Eight Relays

The UR4-8 Universal Door Control Module is a microprocessor based relay controller that provides multiple preprogrammed, field-selectable modes for controlling and interlocking two, three or four doors, using electric door locking devices.

The standard UR4-8 allows:
Complex interlocking and control of 1-4 doors.
Complex input/output linking for up to 8 sets of input and output points
Control of doors using access control system, standalone readers, keypads, or pushbutton switches.
Continued interlock operation, even if system or network fails (as long as power is backed up)

Features:

• 3 selectable Interlock (airlock, mantrap) modes
• Communicating (shared) bathroom mode
• Single or Dual input/output linking modes with outputs configurable as:
      o Conventional Relay (CR) – Input Tracking
      o Latching Relay (LR) – Pulse on, pulse off – Toggle Mode
      o Time Delay Relay (TD) – 1-65 seconds - Timed Output
      o Dual Function Relay (CR/LR, TD/LR, TD/CR, CR/CR)
• Each output relay is field selectable as a dry contact or a “wet” voltage output
• Centralized wiring for all locks, access controls, monitoring contacts, and peripheral equipment
• Onboard input/output status lights for easy troubleshooting
• 3 system control inputs: Lock All, Unlock All, System Lockout
• Emergency release input for fire panel interface
• Removable terminal blocks simplify installation
• Customized solutions can be special-ordered (contact factory for information)
• Power with 12 or 24VDC
• Provides isolation and fuse protection for access control panels and door locking devices
• Can be installed inside an SDC 600RFA (large enclosure) Series Power Supply
