Typical applications include the protection of:

• HVAC units - outdoor or roof mounted
• Outdoor generators
• Perimeters and fences
• Copper ground bars, ground rods and transmissions lines, such as found at  cellular, TV and radio transmission sites
• Copper cable spools and other copper or aluminum products

The principle behind the OLS is simple - run a single strand of fiber optic cable from the module, to and through the device being protected and then back to the module to create a fiber optic loop. As long as the loop remains intact, the module will assume that everything is OK, but as soon as the fiber is broken, the module will pull the relay to provide either an open contact or a closed contact, depending on the requirements. This relay action will act as an alarm trigger when interfaced with your existing security system.

The main reason for using a fiber loop is that it's very difficult, if not impossible, to circumvent. Unlike copper, which can be bridged to make it appear that the loop is still intact, fiber cannot be easily bridged. A typical application would be to run the fiber loop from the OLS module through a small hole in a copper buss bar. Once this is done, the only way that a thief would be able to remove the buss bar from the site would be to break the fiber loop, and once this happens, the relay will operate and trigger an alarm.

Another benefit of using a fiber loop is that it's immune to lightning strikes, high voltage spikes and EMI/RFI interference. You can rest easy knowing that your monitoring points will not be rendered useless because of damage from electrical spikes or by RF interference from nearby transmitters.
