ADJUSTMENTS FOR REQUIRED AREA PATTERN
The CX-702 MKII is designed to provide ideal detection areas for different patterns ranging from 12 m (40 ft.) to 21 m (70 ft.) Wide Angle, and
24 m (80 ft.) to 45 m (150 ft.) Long Range. The following adjustments will provide ideal detection areas for each of these requirements.
1 DETERMINE THE AREA PATTERN
Before making adjustments, determine the pattern area, detection range mounting height.
2 SELECTING WIDE ANGLE OR LONG RANGE DETECTION
1. Inverting the lens will select either the Wide Angle or Long Range detection patterns.
2. Please note markings "W (Wide Angle) " and "L (Long Range) ", on each side of lens.
3. For Wide Angle, "W" will be on top of lens.
4. For Long Range, "L" will be on top of lens.
3 VERTICAL ADJUSTMENT OF DETECTION AREA
Adjust the vertical angle according to the desired detection range and mounting height.
1. Set the upper edge of the lens at either the "A", "B" or "C" position.
2. The following chart illustrates the different position setting.
3. Confirm the detection area by conducting a walktest.

FUNCTIONS
CAUTION
Always conduct a walktest after
changing the position of this
switch to ensure the detector is
still providing optimum coverage.
Power wires should not exceed the following lengths.

● When using two or more units on one wire, the maximum length is
obtained by dividing the maximum wire length listed above by the
number of units used.

Jumper Pin Switch
The Alarm LED indicator can be switched either "ON" or "OFF".

2 PULSE COUNT
The Detection Mode can be switched to either "2" or "4" mode
depending on the environmental conditions of the installation.
2 : For normal applications.
4 : For use in hostile areas where there may be movement of small
animals or other objects such as fax machines or curtains.
When the "4" is selected, the detector's sensitivity may seem sluggish. It is
therefore important to always conduct a walktest to ensure that the desired
coverage is given.
Do not use pulse count 4
for Long Range detection.
