Bosch Security Systems Inc. 850 用户手册

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.

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.

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:

(1)

this device may not cause harmful interference, and

(2)

this device must accept any interference received, including
interference that may cause undesirable operation.

Changes or modifications not expressly approved by Detection
Systems, Inc. can void the user’s authority to operate the
equipment.

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.

•

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.

The PIR detector will react to objects rapidly changing
temperature within its field-of-view.

•

Eliminate interference from nearby sources.

Microwave energy will pass through glass and most
common non-metallic construction walls.

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.

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.

•

Select a location likely to intercept an intruder moving across the
coverage pattern.
