Installation Instructions for the
OD850 Outdoor
PIR/Microwave Intrusion Detector
1.0 Description
The OD850 is a 50 ft. by 50 ft. (15 m by 15 m) PIR/Microwave
intrusion detector that is intended for use outdoors and in other
harsh environments. By using Motion Analyzer II PIR signal
processing and Linear Travel Distance (LTD) microwave
processing, the detector can measure the linear travel distance of
a target to provide excellent catch performance of people while
ignoring stationary objects with slight movement such as tree
limbs and hanging signs. The combination of advanced
processing techniques and mechanical design combine to provide
a detector that offers superior performance in a wide range of
weather conditions.
NOTE:
The use of brackets may reduce range and increase dead
zone areas.

Compliance: This device complies with Part 15 of the FCC Rules and
with RSS-210 of Industry and Science Canada. Operation is subject to
the following two conditions:
This product is covered by one or more of the following
U.S. patents #4,660,024, #4,764,755, #5,208,567,
#5,262,783, and #5,450,062. Other patents pending.
(1) this device may not cause harmful interference, and

Installation Considerations
•
Dimensions (HxWxD): 6.5 in. x 3.25 in. x 2.25 in.
(16.5 cm x 8.25 cm x 5.7 cm)
For UL installation requirements, the unit shall only be installed outdoors
for primary protection in high security installations where unwanted alarms
would be tolerated. Otherwise, the outdoor device should be used for
supplementary protection only, and be connected to a trouble zone or to a
zone that is not programmed for off-premises transmission.
•
Input Power:
10-15 VDC @ 22 mA standby. Maximum
current 62 mA. Use only a Listed Limited
Power Source.
•
•
Standby Power:
No internal standby battery. Standby
power must be provided by a Listed
Limited Power Source. For UL
Certificated installations, four hours (88
mAh) standby power must be provided
by the control panel or by a Listed
burglary power source.
Never install the detector in an environment that causes an alarm
condition in one technology. Good installations start with the LED
OFF when there is no target motion. It should never be left to
operate with the LED in a constant or intermittent green or red
condition.
•
Point the unit away from traffic (roads/alleys) even if they are
outside the coverage area.
•
Avoid installations where hanging signs, trees or other objects
that will be moved by wind are within the coverage pattern or
where wildlife may be moving within the coverage pattern .
•
Point the unit away from objects that may change temperature
rapidly.

NOTE:
•
The PIR detector will react to objects rapidly changing
temperature within its field-of-view.
Eliminate interference from nearby sources.
NOTE:
3.1
Microwave energy will pass through glass and most
common non-metallic construction walls.
Tamper Options
The unit has a built-in cover tamper that will signal when the
detector unit (Figure 3c) is separated from the mounting plate
(Figure 3b). Optionally, the unit can be installed so the tamper will
also signal if the entire unit is pulled away from the surface on
which it is mounted.
NOTE:
•
The wall/cover tamper option is only available when the
unit is surface mounted. The cover tamper is automatic
with all mounting options.
Determine whether the tamper switch is to be used as a cover
tamper or a wall/cover tamper:
for a wall/cover tamper, using an appropriate screw,
fasten the Mounting Plate Tamper section (Figure 3a)
to the wall.
for a cover tamper, do not attach the Mounting Plate
Tamper section to the wall.
4.0 Mounting
WARNING: All wires should remain disconnected from the
power supply until all detector mounting and wiring
procedures are completed.
•
Select a location likely to intercept an intruder moving across the
coverage pattern.
NOTE:
This detector features a Fresnel lens to focus infrared
energy onto a sensor and an offset Look Down lens that
adds a Look Down Zone. The coverage pattern of these
lenses is shown in Figure 1.
•
The surface must be solid and vibration-free.
•
Mounting height range is 7 to 9 feet (2.1 to 2.7 m). Recommended
mounting height is 7 feet ( 2.1 m).
NOTE:
Mounting height recommendations are based on level
surfaces. If the terrain is not level, adjust the mounting
height and detector angle to provide the best coverage.
Refer to the coverage patterns and Section 8.0.

6.2 LED Disable (SW0; Factory Setting ON)
This switch setting determines whether or not the LED will light
during alarm situations. This switch should be ON (LED enabled)
during walk testing, but may be OFF (LED disabled) during normal
detector operation to save power.

Terminal Descriptions
The detector features two user-selectable PIR Sensitivity settings
as follows:
•
Standard Sensitivity: Recommended setting for maximum false
alarm immunity. Tolerates environment extremes on this setting.
•
Intermediate Sensitivity: Recommended setting for any location
where an intruder is expected to cover only a small portion of the
protected area. Tolerates normal environments on this setting.
This setting will improve your intruder catch performance.

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.
•
The LED should be OFF before walk testing.
NOTE:
•
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.
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)
at least ten seconds between the following walk testing
procedures.
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.
CAUTION:
NOTE:
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:
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.
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.

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:
•
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.
