ESCRIPTION
The DDI78 (Passive Infrared And Microwave Intruder Detector) is an
outdoor Dual Technology Sensor designed to provide volumetric protec-
tion. The sensor uses the unique combination of Stereo Doppler
Microwave and Passive Infrared (PIR) technologies.
DDI78 is configured for "And Gate" operation; i.e. both technology
portions must activate simultaneously for the sensor to alarm.
For optimum performance it is best to use the DDI78 as a motion sensor
to protect specific assets and strategic areas. Generally the sensor is
not used along a perimeter fence area.

Check the LED On/Off switch to verify that it is in the "ON" position. The
LED On/Off switch controls the "Walk Test" LED's and the Voltage OK
LED.
Note: For best shielding from Radio Frequency Interference (RFI) and
transients due to lightning or electrostatic discharge, Aritech highly
recommends the use of shielded cable. When shielded cable is used,
the cable shield (and/or drain wire) should be connected to Terminal 1
(Housing GND) at each sensor. Terminal 1 is connected by a spring
