About Express System Monitoring

LightLOC is a patented, fiber optic based security system providing the optimum in perimeter and access security.  The system provides monitoring of remote access points and perimeters using a family of sensors and cables developed and made by LightLOC.  The robustness of the system eliminates false alarms commonly seen with other fiber-based security systems.  Monitored items can include manholes, gates, doors, culverts, perimeter vehicle detection, vehicle denial cable systems, and custom applications.  Monitoring is possible at distances of up to 25km without the need for electrical power at the monitored locations.  LightLOC systems are inherently tamper resistant since altering or destroying optical components will trigger alarms automatically.

LightLOC Express is a modular monitoring device in the LightLOC family of products.  It is a zoned-based version of the Network Level OTDR-based LightLOC system and works by monitoring the power level of optical energy being transmitted and received through a system.  It is capable of monitoring any of the LightLOC sensing devices over miles of fiber like the Network System but is ideal for discrete points, small systems, and zones since it does not provide breach location capability.  Express is an adaptable device that learns the secure state of the system it is monitoring and continuously compares its current received power level to the stored value.  If the power level drops below or goes above a preset threshold level, an alarm is generated in less than a second.  Relay outputs are provided, and the module can differentiate between a breach (minor) alarm and break (severe) alarm on the fiber.  Express is available as a stand-alone module or housed in a 2U rack-mount chassis capable of holding up to seven modules.  It is rated for indoor or outdoor use.
