If the time period selected has elapsed from the last detector alarm,
a supervision trouble condition will be signaled. Refer to the
Supervision Features section for more information.
NOTE
:
If this feature has been enabled, and you wish to use the
Memory feature, the Microwave Inhibit feature will be disabled.

Trouble Memory
Short the Trouble Memory contacts with a flathead screwdriver. The
LED will indicate the last trouble condition that occurred.

To adjust the vertical starting angle for the desired mounting height
and range, loosen the vertical adjust screw and slide the board up, to
point the angle down. Note the settings on the vertical adjust scale.
•
Place the LED plug in the ON position and replace the cover.
7.1
Establishing PIR Pattern Coverage
•
Turn the Microwave range adjust to minimum.
•
Replace the cover and snap it into place. This will close the
tamper switch.
•
Wait two minutes minimum
after applying power to start walk
tests.
NOTE
:
During the warm-up period, the tri-color LED will flash red
until the unit has stabilized (approximately 1 to 2 minutes)
and has seen no movement for two seconds. When the tri-
color LED stops flashing, the detector is ready to be tested.
With no motion in the protection area, the tri-color LED should
be OFF. If the LED is on, re-check the protection area for
disturbances affecting the microwave or PIR technologies.
•
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 tri-color LED. The edge
of the pattern is determined by the first green, PIR activation of
the LED (or the first red activation if the yellow microwave LED
activates first).
•
Walk test from the opposite direction to determine both
boundaries. The center of the pattern should be pointed toward
the center of the intended protection area.
NOTE
:
The pattern may be moved ±10° horizontally by rotating the
lens window left or right.
•
Slowly bring your arm up and into the pattern to mark the lower
boundary on PIR alarm. Perform this task at 10 to 20 ft. (3 to 6 m)
from the unit. Repeat from above for the upper boundary.
The
center of the pattern should not be tilted upward
.
NOTE:
If desired coverage cannot be achieved, try angling the
coverage pattern up or down to assure the pattern is not
aimed too high or low. The angle of the PIR pattern may be
vertically positioned between -10° and +2° by loosening the
Vertical Adjust screw and sliding the circuit board up or down.
Moving the board up will angle the pattern downward.
•
Tighten the screw snug when positioning is completed.
7.2
Establishing Microwave Coverage
NOTE
:
It is important to wait one minute after removing/replacing
the cover so the microwave portion of the detector can settle,
and to wait at least ten seconds between the following walk
testing procedures.
•
The tri-color 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 tri-color LED. The edge of the microwave pattern is
determined by the first yellow, 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.
NOTE:
Do
not
adjust the microwave range higher than required.
Doing so will enable the detector to catch movement outside
of the intended coverage pattern.
•
Walk test the unit from all directions to determine all the Microwave
pattern boundaries. Wait at least ten seconds between walk
tests.
7.3
Establishing Detector Coverage
•
The tri-color LED should be OFF before walk testing.
•
Walk test the unit from all directions to determine the detection
boundaries. A detector alarm is signaled by the first red activation
of the tri-color LED after an initial green or yellow activation.

Meter Tests
A 20,000
Ω
/V (or greater) analog DC VOM is recommended. Set the
meter scale for 5 VDC (Use of the TC6000 is recommended, but is
not essential for meter use. Either outside connector pin of the TC6000
may be used for common.).
8.1
PIR Meter Readings
•
Connect the meter to the PIR Noise Voltage Pins.
•
With no target motion in the pattern, read the voltage.
NOTE:
The base reference level for PIR background noise is
approximately 1 VDC. Installations in quiet environments,
therefore, should result in a steady meter reading between
0.9 VDC and 1.1 VDC.
•
Walk test
across
the farthest edge of the coverage pattern. Make
sure the detector’s cover is on.
NOTE:
Voltage changes greater than +0.75 VDC from the reference
level during walk tests
are desirable
. If changes are less
than 0.75 VDC, the detector may fail to respond at this far of
a distance if the temperature difference between the intruder
and the background is minimal. Try adjusting the unit up
and down to maximize the voltage change during walk tests.
•
Turn on all heating/cooling sources that will be in operation during
times of protection. Stand away from the unit and outside the
protection pattern, then monitor background noise for at least
three minutes.
NOTE:
Readings should not deviate more than 0.15 VDC from the
reference level. If they do, eliminate the cause or reposition
the pattern (observe readings while turning on and turning
off these sources as well as during the three minute interval).
