    Encoded Relay Module for PC Programming
    K-Prox/K-Smart controllers provide 3 Open Collector outputs. In order for these outputs to trigger an electrified lock or other auxiliary device, they must be tied to either external relays or an optional Essex Encoded Relay Module (Part No. ERM-3). In addition to providing the features listed above, the Encoded Relay Module includes:

  • 3 SPDT Relays (6 amp, 120VAC)
  • 12 to 24 VAC or DC Input
  • Ability to add optional Battery Backup System

    Essex EZ Key PC Programming Software
    Essex EZ Key Software: PC Programming & Logging Software Serial Communications Interface: Ties the Encoded Relay Module to a PC for system programming/real time logging

  • Use EZ Key to set the System configuration
  • Add, modify or delete users through EZ Key User Maintenance
  • Record real time logging (while running KeyLog on a PC connected to an ERM-3 Encoded Relay Module)
