Field-Device Programmer / Test Unit
Model OH921 is compatible with the Siemens field-device programmer / test unit (Model 8720 | DPU), which is a compact,
portable and menu-driven accessory for electronically programming and testing these addressable detectors promptly and
reliably. For instance, the field technician selects the accessory’s program mode, and enters the desired address.
Model DPU eliminates the need for cumbersome, unreliable mechanical programming methods (e.g. – dials and rotary
switches), and reduces installation and service costs by electronically programming and testing the detector prior to
installation. When set in `test’ mode, Model DPU will perform a series of diagnostic tests without altering the address or
other stored data, allowing technicians to determine if the detector is operating properly.
Each field-device programmer / test unit operates on
AC power or rechargeable batteries, providing flexibility and
convenience in the programming / testing of fire-safety equipment from practically any location.
Additionally, with the use
of a Model DPU unit, there is no longer a cause for concern with any vibration, corrosion and other deteriorating conditions
that can accompany the vitality of a mechanical-addressing mechanism.
The encompassing result is an intelligent detector that provides enhanced detection capability to a wide range of products
of combustion – while offering unsurpassed rejection to nuisance-alarm sources, including: dust | steam | aerosols and
other deceptive phenomena that could cause false alarms.
