These detectors are covered under one or more of the following U.S. patents: #4,660,024, #4,764,755, #5,077,548, #5,208,567, #5,262,783, #5,450,062 and #5,670,943. 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.

3. Mounting

3.1 Mounting Considerations

• Never install the detector in an environment that

causes a constant alarm in one technology; it should never be left to operate with the LEDs in a constant flashing green, yellow, or red condition. A detector with one technology in constant alarm will cause an alarm output whenever the other technology alarms. Good installations start with the LEDs OFF when there is no target motion.

• Point the unit away from outside traffic (for

example, roads, alleys, and parking lots).

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

• Avoid direct or indirect sunlight.

• Point the unit away from glass exposed to the

outdoors and objects that may change temperature rapidly (see Figure 1)

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

Figure 1: Avoid extreme temperature change

locations

• Eliminate interference from nearby outside

sources.

• Avoid installations where rotating machines (such

as ceiling fans) are normally in operation within the coverage pattern (see Figure 2).

Figure 2: Avoid installing near rotating machines

• Select a location likely to intercept an intruder

moving across the coverage pattern (see Figure 3).

Figure 3: Coverage Pattern

Avoid mounting the detector in locations (such as above a doorway) where people can pass in close proximity (0.5 m / 1.5 ft.) of the detector.

• The surface should be solid and vibration-free.

• Mounting height range is 1.8 m to 2.4 m (6 ft. to

8 ft.). The recommended height is 2.3 m (7.5 ft.). Mounting height for Pet Applications is 2 m (6.5 ft.).

During walk testing, the LEDs light for the first technology (microwave or PIR) and then light red to indicate a detector alarm. The LEDs will not indicate activation of the second technology with color.

If the detector experiences a Microwave or PIR self-test failure, it is in need of replacement.

6. Mirror Alignment

7. Walk Test

1. Wait at least two minutes, after applying power, to

start walk tests.

During the warm-up period, the LEDs will flash red, yellow and green until the unit stabilizes (approximately one to two minutes) and has not registered movement for two seconds. When the LEDs stop flashing, the detector is ready to be tested. With no motion in the protection area, the LEDs should not be flashing. If the LEDs are flashing, recheck the protection area for disturbances affecting the microwave (yellow) or PIR (green) technologies.

7.1 Establishing PIR Pattern Coverage

1. Enable Walk Test via the keypad.

2. Turn the Microwave range adjust to minimum

(counter-clockwise) and replace the cover.

Figure 7: Microwave Range Adjustment

The center of the pattern should be pointed toward the center of the intended protection area.

6. If the desired coverage cannot be achieved, try

angling the coverage pattern up or down to assure the pattern is not aimed too high or low.

7.2 Establishing Microwave Coverage

Wait one minute after removing/replacing the cover so the microwave portion of the detector can settle. Wait at least ten seconds between the following walk testing procedures.

1. Enable Walk Test via the keypad.

2. The LEDs should be OFF before walk testing.

3. Walk test across the pattern at the intended

coverage’s farthest end. Start walking from outside the intended protection area and observe the 3 colored LEDs. The edge of the microwave pattern is determined by the first yellow, microwave activation of the LEDs (or the first red activation if the LEDs show green first).

4. 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.

Do not adjust the microwave range higher than required. Doing so will enable the detector to catch movement outside of the intended coverage pattern.

5. Walk test the unit from all directions to determine

all the pattern boundaries.

7.3 Verify Detector Coverage

The LEDs should be OFF before walk testing.

3. 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 three colored LEDs. The edge of the pattern is determined by the first green PIR activation of the LEDs (or the first red activation if the yellow microwave LED activates first).

4. Walk test from the opposite direction to determine

both boundaries.

5. While standing 3 m to 6 m (10 ft. to 20 ft.) 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.

Bosch Security Systems | 9/03 | PRELIMINARY 4998132113Ar11

1. Walk test the unit from all directions to determine

the detection boundaries. A detector alarm is signaled by the first red activation of the 3 colored LEDs after an initial green or yellow activation.

DS840LSN | Installation Guide | 8. Supervision Features EN | 7

8. Supervision Features

The supervision features function as follows:

• PIR/Microwave: The complete circuit operation

of these subsystems is checked approximately every 12 hours. If the PIR or microwave subsystem fails, this will be communicated to the control panel.

• Default: The detector will default to PIR

technology protection if the microwave subsystem fails.

9. Other Information

• Maintenance: At least once a year, the range and

coverage should be verified. To ensure continual daily operation, the end user should be instructed to walk through the far end of the coverage pattern. This ensures an alarm output prior to arming the system.

• Pattern Masking: The PIR coverage pattern may

be masked using masking tape or electrical tape on the inside of the mirror.

Many adhesives will either destroy the mirror surface or leave enough residue behind to degrade the coverage performance. Be sure to clean the mirror surface with a mild window cleaning solution after masking removal.

10. Using Pet Immunity

The DS840LSN detector provides reasonable protection from nuisance alarms caused by the following sources:

• One dog up to 27 kg (100 lbs.)

• Up to 10 cats

• Multiple small rodents, such as rats

• Random flying birds

The Pet Filter is not a mirror mask. Use only the supplied filter for pet applications.

To take full advantage of the Pet Immunity feature, the following steps should be followed:

1. Add the Pet Filter to the mirror (included in the

hardware bag). See Figure 8.

Figure 8: Applying the Pet Filter

Masking only eliminates the PIR portion of the coverage and has no affect on the microwave pattern.

Add the Pet Filter for pet applications only.

1 - Pet Filter 2 - Mirror Assembly

2. Mount the detector 2 m (6.5 ft.) high and adjust the

Mirror angle as in Section 6. Mirror Alignment.

3. Mount where the animals can not come within

1.8 m (6 ft.) of the detector by climbing on furniture or other objects.

4. Adjust the microwave range for the minimum

acceptable coverage for the room in which the detector is installed.

Pet immunity is only available when using the filter provided with the detector. This pet nuisance protection has not been verified by Underwriters Laboratories, Inc
