Enhanced Immunity Setting - Often used as a last resort to eliminate
nuisance alarms caused by an abundance of birds and animals in the
protected area. The use of this setting is also highly recommended in
animal prone applications. In the Enhanced Immunity Setting, overall
detection sensitivity of the DDI78 sensor will be reduced approximately
20%.
CAUTION! In the Enhanced Immunity Setting the speed of
detection is significantly reduced. Therefore, the DDI78 sensor
may not detect an intruder or a vehicle traveling at a rate of speed
above 1 m/sec.

The DDI-78 Tester plugs into the face of the sensor and is a significant
aid in walk testing the sensors. Aritech strongly recommends its use.
