Siemens AD-HR

Description

The AD-HR air duct housing is uniquely designed to use the photoelectric detector. HFP-11 sensitivity may be viewed from the multi-color LED on the detector or preferably may be printed by command on an optional printer from the FireFinder XLS control panel. The multi-color LED on the HFP-11 flashes green to indicate the detector has passed it’s self test and is within its proper sensitivity range. Yellow indicates either a ”Trouble” condition or an ”Out of Sensitivity” condition. Red indicates alarm.
