Specifications

Dimensions

6.5 in. x 3.25 in. x 2.25 in. (16.5 cm x 8.25 cm x 5.7 cm)

Input Power

10 VDC to 15 VDC @ 22 mA standby. Maximum current 42 mA. Use only a Listed limited-power source.

Standby power must be provided by a Listed limited-power source. For UL Certificated installations, 4 h (88 mAh) standby power must be provided by the control panel or by a Listed burglary power source

Alarm Relay

Form “A” normally closed (NC), supervised alarm contact opens on alarm. Form “C” unsupervised, timed relay contact transfers on alarm and follows an installer programmable timer

IP Rating Options :

B335 Low Profile Swivel Mount Bracket (supplied), B328 Swivel Mount Bracket, B338 Ceiling Mount Bracket, Pole Mount Bracket (supplied).

Note : Misaligning the detector in these brackets can reduce the detector’s range and increase the dead zone area

Compliance

OD850-F1 complies with Part 15 of the FCC Rules and with RSS-210 of Industry and Science Canada. Operation is subject to two conditions:

1. This device cannot cause harmful interference.
2. This device must accept any interference, including interference that might cause undesired operation

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

Installation Considerations

Never install the detector where the PIR or microwave is in constant alarm (LED on). The LED is off when properly installed.

Point away from traffic.

Avoid installing where hanging signs, trees or other objects that the wind can move are within the coverage pattern or where wildlife might move within the coverage pattern.

The mounting surface must be solid and vibration-free.

UL Listing 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.

Warning

• Apply power only after all connections are made and inspected. Do not coil excess wiring inside detector.
• Do not connect any terminal to any power supply providing more than 25 VDC.

Coverage Patterns

Microwave coverage
PIR coverage
Look-down zone

Note : When choosing the appropriate mounting height for your application (particularly, when the terrain is not level) the upper finger is the strongest and responds more quickly to an intruder’s presence. Every finger shown in the top view (3-1) has the same side view (3-2) configuration.

Mounting

1. Select a mounting location. Mount the sensor where an intruder is most likely to cross the coverage pattern.

2. Mount the detector 7 ft to 9 ft (2.1 m to 2.7 m) above the ground. Recommended: 7 ft (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.

3. Slide the mounting plate down (4-1) until you hear a click, and remove it from the cover.

4. Mount the mounting plate using one of these options:
   

Note : Do not remove the waterproof label from the mounting plate (4-2). Push the mounting screws or wiring knockouts through the label as needed

• Surface mount using a single-gang electrical box.

  1. Install a single-gang electrical box at the detector location.
  2. Attach the mounting plate (4-3) to the single-gang box with the appropriate screws.

• Surface mount without an electrical box.

  1.  Select an appropriate location.
  2. Using the mounting plate (4-1) as a template, mark the location of the mounting screws and the wire run.
  3. Attach the mounting plate (4-1) to the wall with the appropriate screws.

• Surface Mount using the supplied B335 Bracket or an optional bracket. Use the bracket’s instructions  to attach the bracket to the appropriate mounting surface.

• Attach the B335 Bracket to the mounting plate. (4-4).

• Attach the B328 Bracket to the mounting plate. (4-5).

• Attach the B338 Bracket to the mounting plate. (4-6).

• Pole Mount using the supplied bracket.

Note : Do not mount to fence posts that might sway in the wind.

• Attach the bracket (4-7) to the mounting plate (4-8) using the appropriate screws and mounting holes.

• Two hose clamps (not supplied) large enough to fit around the pole are recommended for fastening the detector mounting plate to the pole.

Tamper Options

The unit has a built-in cover tamper that signals when the detector unit (4-9) separates from the
mounting plate (4-1). The unit can also be installed so the tamper signals if the entire unit is pulled away from the surface on which it is mounted.

Note : The wall and cover tamper option are only available when the unit is surface mounted. The cover tamper is available with all mounting options.

Determine whether the tamper switch is to be used as a cover tamper or a wall and cover tamper

• Wall and cover tamper: Use the appropriate screw to fasten the mounting plate tamper section (5-1) to the wall.
• Cover tamper: Do not attach the mounting plate tamper section (5-1) to the wall.

Note: The OR mode is not recommended for most installations. The OR mode provides faster detection in some conditions. Itcan also increase the likelihood of nuisance alarms because the detector activates the alarm relay based on input from a single technology.| ON: AND Mode (recommended) OFF: OR Mode, you must also cut the jumper (4-10).

Attaching Detector to Mounting Plate

1. When all wiring is connected to the detector but not to the power supply and all the settings are made, slide the detector unit (4-9) onto the mounting plate (4-1) and down until it is firmly seated. Avoid pinching the wires.
2. With a small flat head screwdriver, turn the locking cam (9-1) 180o to lock (9-2) the detector unit to the mounting plate. Avoid excessive force.
   

Walk Test

Note : Ensure the detector is fastened to the mounting plate and all wiring is connected and powered before beginning the Walk Test.

Note : Ensure the LED Disable (SW0) is on (refer to Section 7 DIP Switch Configuration).

Note : To avoid false alarms, set the microwave range (10-1) to its minimum setting before starting the Walk Test.

Microwave coverage
PIR coverage

1. Wait at least 2 minutes after power up to start the Walk Test.
   The LED flashes red until the detector stabilizes and no movement is detected for 2 seconds.

2. Watch the LED as you walk towards the edge of the pattern (10-2). The LED lights at the outside edge of the coverage range.

3. Repeat Step 3 from different directions until you adequately verify the coverage pattern.
   The green LED lights, identifying the PIR pattern edge.
   The green LED flashes, identifying the microwave pattern edge.

4. Repeat Step 3 from the opposite side.

5. If the required range is not achieved, increase the microwave adjustment (10-1) by turning it clockwise slightly.

6. Repeat the walk test and adjustments until you reach the farthest edge of coverage needed.
