The LCM-2500 Discrete Relay Interface (DRI) is designed to monitor the security status of virtually any access portal such as handholes, hatchways, manholes, and vaults when integrated with LCM 600 series Interlock Switches.

Features 

• Eight (8) optical channels.
• Up to eight (8) optical switches per channel.
• Each optical channel utilizes one strand of SM fiber with several uniquely addressed switches installed in series.
• Each switch is monitored continuously, and intrusion events are immediately reported by the DRI.
• Switches may be located up to 16km distant from the equipment location.
• The DRI is designed to display and control alarm event switching for up to 64 fiber optic tamper switches.
• Custom configurations are available for larger sensor count systems as well as Physical Security Information Management (PSIM) software-based systems where C3 or C4 integration is required.
