Siemens DPU (500-033260) is a portable, menu-driven device programming and test unit that addresses and tests Siemens addressable field devices, and doubles as a loop tester and ground-fault detector, before any of it goes on the wall.
The DPU programs an address into a device's non-volatile memory, then tests the device so the installer knows it works before installation. Detectors are programmed by dropping the head into the integral DB-11 base on the unit; other devices connect through the supplied programming cable. A backlit LCD and keypad walk the user through program and test menus, and the address auto-increments as devices are done. Before a device circuit is connected to the panel, the loop can be run from the DPU to find ground faults and debug the circuit. The unit ships with NiMH rechargeable batteries, an AC power supply, a storage compartment for the programming cable, and a DB-3 base adapter for IL-series detectors on MXL systems.

Installation notes
-
Loop test needs AC power: the DPU only runs the loop test on AC power because of the current draw.
-
Loop and ground-fault testing is FireFinder XLS only: in MXL mode the DPU programs and tests devices but does not run loop or ground-fault tests, and the feature works only with H-series FireFinder XLS devices.
-
Switch off the charger for alkalines: a switch in the battery compartment disables charging when AA alkaline cells replace the NiMH pack.
-
Bench tool: the DPU programs and verifies devices before installation and is not part of the installed system.
