Cut Sheets & Documents: Premise Control Unit with Dual Adjustable Power Supply Model: CU5-6 The Model CU5-6 Premise Control Unit with Dual Adjustable Power Supply provide a physical enclosure interface for devices used in securing a specific area. The CU5-6 interfaces various detection devices in the secured area to a monitoring facility which is located away from the secured area. The detection devices consists of electrically ‘closed’ switch or relay dry contacts which ‘open’ when a specific change is detected. The detection devices are interfaced to the monitoring facility (i.e., Desplex series MP5 Receiver Module), via a transmission module (i.e., Desplex series TM5 Transmission Module) installed in the CU5-6 enclosure. The detection devices are typically Passive Infrared motion detector, Dual Tec (PIR/Ultrasonic) motion detectors, vibration detectors or any other detectors requiring a DC (i.e., 13.5 VDC) power source used in protecting the secured area.
