technology senses an alarm state). Setting the switch ON selects
the AND mode (recommended); setting the switch OFF and cutting
the jumper (see Figure 3i) selects the OR mode.
NOTE: OR mode is not recommended for most installations. OR
mode will provide faster detection in some conditions, but
may also increase the likelihood of nuisance alarms as
the detector will activate the alarm relay on a single
technology activation..
6.6 Day/Night Mode (SW5; Factory Setting OFF)
With the control unit armed and this switch OFF, the unit will alarm
day or night. With the control unit armed and this switch ON, the
unit will not alarm during daylight.
NOTE: If the LEDs are enabled (SW0), then LED indications will
still continue.
NOTE: The seventh switch (SW6) is not used.
7.0 Attaching Detector Unit to Mounting Plate
• When all wiring has been connected to the detector (but not to
the power supply) and all the settings have been made, slide the
detector unit (Figure 3c) onto the mounting plate (Figure 3b) and
down until it is firmly seated. Avoid pinching the wires.
• With a small screwdriver, lock the detector unit to the mounting
plate by turning the Locking Cam (Figure 3d) one half turn to
lock . Avoid using excessive force.
NOTE: Figure 3d1 shows the Locking Cam in the unlocked
position; while Figure 3d2 shows it locked.
8.0 Testing the Detector
NOTE: The detector unit should be fastened to the mounting plate
before testing the unit.
• Place the LED Disable (SW0) in the ON position.
• Connect the wires to the power supply and apply power.
NOTE: Wait at least two minutes, after applying power, to start
walk tests. During the warm-up period, the LED will flash
red until the unit has stabilized (approximately one to two
minutes) and has seen no movement for two seconds.
When the LED stops flashing, the detector is ready to be
tested. With no motion in the protection area, the LED
should be OFF. If the LED is ON, recheck the protection
area for disturbances affecting the microwave (flashing
green) or PIR (green) technologies.
Establishing PIR Pattern Coverage
• Walk test across the pattern at its farthest edge, then several times
closer to the detector. Start walking from outside of the intended
protection area, and observe the LED. The edge of the pattern is
determined by the first green (PIR) activation of the LED (or the first
red activation if the flashing green microwave LED activates first).
• Walk test from the opposite direction to determine both boundaries.
NOTE: The center of the pattern should be pointed toward the
center of the intended protection area.
• While standing 10 to 20 ft. (3 to 6 m) from the detector, slowly bring
your arm up and into the pattern to mark the lower boundary on PIR
alarm. Repeat from above for the upper boundary.
NOTE: The center of the pattern should not be tilted upward.
If the desired coverage cannot be achieved, try angling the coverage
pattern up or down using a swivel bracket to assure the pattern is
not aimed too high or low.
Establishing Microwave Coverage
NOTE: Wait one minute after removing/replacing the detector unit
so the microwave portion of the detector can settle. Wait
at least ten seconds between the following walk testing
procedures.
• The LED should be OFF before walk testing.
• Walk test across the pattern at the intended coverage’s farthest
end. Start walking from outside the intended protection area and
observe the LED. The edge of the microwave pattern is determined
by the first flashing green (microwave) activation of the LED (or the
first red activation if the green PIR LED activates first).
• If adequate range can not be reached, increase the Microwave
Range Adjust slightly. Continue walk testing (waiting one minute
after removing/replacing the cover) and adjusting the range until
the farthest edge of desired coverage has been accurately placed.
CAUTION: Do not use excessive force when adjusting the
microwave pot.
NOTE: If you adjust the range, set the adjustment as low as
possible for proper catch performance. Be sure to walk
test throughout the coverage pattern after any adjustment.
• When all walk testing is completed, the LED Disable switch can
be set to disable the LED if so desired.

NOTE: When choosing the appropriate mounting height for your
application (in particular, when the terrain is not level) be
aware that the upper finger is the strongest and will
respond most quickly to an intruder's presence. Also,
every finger shown in the top view (below) has the same
side view configuration as shown (above).
