Model or switches,and reduces installation and service costs by OP921 incorporates an optical sensor using a light- electronically programming and testing the detector prior to scattering detection principle. The device utilizes installation. advanced software algorithms to analyze the signals, For proper operation of the field-device programmer/test and provides highly stable and accurate smoke unit,the technician selects the accessory's program mode, detection. and enters the desired address. In turn, Model 8720/DPU Further, Model OP921 uses state-of-the-art automatically sets and verifies the address,as well as tests microprocessor circuitry with error check;detector self- the detector. When in the'test'mode, Model 8720 I DPU will diagnostics,and supervision programs. perform a series of diagnostic tests without altering the Field-Device Programmer/Test Unit address or other stored data,allowing technicians to determine if the detector is operating properly. Model OP921 is compatible with the Siemens field-device programmer I test unit(Model 8720/DPU), Model 8720 I DPU operates on AC power or rechargeable which is a compact, portable, menu-driven accessory batteries, providing flexibility and convenience in for electronically programming and testing detectors programming and testing equipment from practically any easily and reliably. location.
