This system allows a method of remotely monitoring an AC or DC power failure over fiber. Each system requires a Transmit Card and a Receive Card, available separately.
The monitored AC or DC power source is connected directly to the RLH Fiber Optic Alarm Transmit Card. The Fiber Optic Alarm Receive Card is located at the opposite end of the fiber optic cable and is locally powered.
The Transmit Card includes an AC/DC power adapter that plugs into a standard AC outlet. This permits direct monitoring of an AC power source.
The DC PWR INPUT on both Receive and Transmit Fiber Optic Alarm Cards are not polarity sensitive, eliminating potential wiring errors. The Fiber Optic Alarm System operates on one fiber strand, and will operate up to 2 miles on multimode fiber, and 6 miles over single mode fiber.
