FiberStrike LCM-2500 Discrete Relay Interface

A 2U rack-mount controller that interrogates networks of FiberStrike fiber optic tamper switches and converts each switch state into a dry relay contact output. Intended for access-point security monitoring at manholes, hatchways and vaults.

Technical overview

The LCM-2500 drives eight optical channels, each carrying up to eight uniquely addressed switches in series on a single strand of single-mode fiber, for a maximum of 64 switches per controller. Switches may sit anywhere on the fiber up to 10 mi / 16 km from the controller over standard telecommunications-grade single-mode fiber. Each switch is monitored continuously and an open or close event activates the associated dry contact relay in under one second. Events are logged on board for historical review, with 4 GB standard storage and a 1 TB option.
