unum DT Anti-Masking Motion Detector
The motion detectors unum DT AM are professional motion detectors of who use the benefits of the Dual-Technology, pet immunity and antimasking.
They represent the top range of detectors for indoor of Ksenia Security.
The unum DT AM detector integrates directly on the card end of line resistors, selected to fit each plant type with comfortable removable jumpers.
OPERATION OF ANTI-MASKING
The mask is detected by two analysis, running simultaneously: the first is an alteration of normal balance between alarm signals from Infrared (PIR) and microwave derived from the analysis continuous signal, using a reduced sensitivity of the microwave to minimize the effect of continuously moving objects that could affect only the microwave.
You can disable this type of analysis acting on a jumper.
The second analysis is based on an area of supervision (within one meters from the sensor): a person entering in the safe zone will activate the detection process of masking.
This second function cannot be disabled.
