The DPU (Device Programmer/Loop Tester) is a Siemens field tool used to configure and test addressable detectors on Cerberus PRO, Desigo Fire Safety, and FireFinder XLS fire alarm systems. Service technicians use it to program detector sensitivity thresholds and verify loop integrity without requiring a panel connection. It interfaces directly with Siemens intelligent detectors mounted in DB-series bases.

Verify panel/device family compatibility before ordering.
