12 Other Features
Apply a control voltage on Terminal 8 to activate
Memory, Night Mode, and Walk Test (refer to Table 3).
The control voltage must be between 6 VDC and 18
VDC.
Use a supply voltage to apply a control voltage to
Terminal 8 (12-1).
Or, use a control panel or external DC power supply as
control voltage (12-2):
- +6 VDC to +18 VDC = On (switch closed)
Day Disables the alarm memory and allows
Mode the LED (if activated) to operate
normally.
Memory When the detector is in Night Mode, the
memory activates. The detector stores
an alarm for display when switched to
Day Mode.
Night Enables the alarm memory and
Mode disables the LED operation.
Walk When the detector is in Walk Test
Test Mode, the LED indicates the current
alarm status regardless of Switch 1's
setting (refer to Section 7 DIP Switch
Confi guration). A stored alarm displays
when the memory input is switched to
Day Mode.
2 Installation Considerations
Not suitable for outdoor use (2-1).
Never install the detector where the passive infrared
(PIR) is in constant alarm (LED on). The LED is off
when properly installed.
Point away from direct and indirect sunlight (2-2). Point
away from glass or other objects that rapidly change
temperatures (2-3, 2-4, and 2-5).
Do not install this detector where pets are present (2-6).
Mount the detector on a solid and vibration free surface.
Note: The detector does not detect through glass.
Warning!
Apply power only after all connections are made and
inspected.

Mounting
1. Remove the cover. Insert a thin fl athead screwdriver
into the notch at the bottom of the cover (5-1) and
lift.
2. Loosen the printed circuit board (PCB) assembly
screw (5-2).
3. Push the PCB assembly (5-3) up towards the top of
the base until you hear a click.
4. Lift (5-4) the PCB assembly out of the base.
5. Use the base (5-5) as a template to mark the
location for the mounting screws.
6. Thread the wires through the wire entrance (5-6) on
the base.
6. Mount the base (5-5) using one of these options:
- For surface or corner mounting, use the
appropriate mounting hole knockouts (5-7) and
the screws and anchors provided.
- For optional bracket mounting, use the
appropriate knockout (5-8) and refer to the
installation instructions supplied with the
bracket.
10. Use the cable ties (5-9) for strain relief.
11. Insert the PCB assembly into the base and slide
the PCB assembly down (5-10) until you hear a
click.
12. Tighten the PCB assembly screw (5-2).
13. Place the cover on the detector.
Anti-mask and Spray Detection
11
Feature
Anti-mask and Spray Detection prevents accidental or
intentional blocking of the detector. This feature detects
an object placed near the detector or detects a foreign
substance sprayed on the detector.
Note: The Anti-mask feature is always on. To disable
this feature, cover the anti-mask transmitter (5-12) with
masking tape.

13 Noise Voltage Verifi cation
Measure the detector noise level at the noise voltage
pins, found behind a metal fl ap on the circuit board
(5-13). Also use this feature to troubleshoot false alarms
caused by environmental changes. When verifying the
noise voltage, test each channels one at a time.
1. Connect a DC voltmeter to the noise voltage pins
using the Bosch TC6000 test cable opening (5-11).
2. Set the meter scale for VDC.
The base reference level for reading background
noise is approximately 2.5 VDC.
Installations in quiet environments result in a steady
reading between 2.4 VDC and 2.6 VDC.

Mirror Alignment
Note: Touching the mirror surfaces can reduce
performance.
Adjust the mirror vertically to set the maximum detection
range (distance) and mounting height. There are angle
adjustment markings on both sides of the mirror (8-1).
Slide the mirror forward or back until the angle adjust-
ment markings align with the markers on each side of
the frame.
Use the chart located inside the front cover (8-2) to set
the correct vertical angle.
Adjust the horizontal protection coverage during the
Walk Test (refer to Section 9 Walk Test).
X = maximum range
Y = mounting height
9
Walk Test
1. Replace the unit's cover. It must be in place before
testing the unit.
2. Wait at least 2 minutes after power up to start the
Walk Test. The LED lights for 1 to 2 minutes until the
detector stabilizes and no movement is detected for
2 seconds.
3. Watch the LED as you walk towards the edge of the
pattern. The LED lights at the outside edge of the
coverage range.
4. Repeat Step 3 from different directions until you
adequately verify the coverage pattern.
5. Adjust the mirror ±10 o horizontally by rotating it from
side to side to ensure adequate horizontal cover-
age.
5. Adjust the mirror up and down, as needed, to en-
sure the coverage pattern is not too high or too low.
Note: To verify the detector clearly views the detection
area, instruct the end user to walk through the outer
edge of the coverage pattern daily. At least once a year,
check detector's the range and coverage.
It takes approximately 25 sec for the detector to react to
a masked or sprayed condition if the anti-mask timer is
on (refer to Section 7 DIP Switch Confi guration). If the
anti-masking circuitry activates, a supervision trouble
condition occurs. The Alarm/Test LED fl ashes three
times, and the trouble relay activates.
Recommendation: Set the anti-mask timer in situations
where false masking events such as dusting the
detector or removing and replacing the cover occur.
After 10 sec of inactivity, the trouble condition
automatically resets the next time the alarm activates.
Momentarily removing power from the detector also
resets the trouble condition.
The size of the anti-mask detection zone varies
depending on Switch 3's setting (refer to Section 7 DIP
Switch Confi guration).
(11-1) Anti-mask detection zone with Switch 3 (Spray
Detect) off.
(11-2) Anti-mask detection zone with Switch 3 (Spray
Detect) on.
(11-3) Keep-out zone: Do not mount the detector within
24 in. (60 cm) of moving objects such as doors,
cabinets, or curtains.
During the Walk Test, voltage changes greater than
0.75 VDC from the reference level indicate the
detector works correctly. If changes are less than
0.75 VDC, the device might fail to respond if the
temperature difference between the intruder and the
background is minimal.
3. Turn on all heating and cooling sources that
normally operate during times of protection.
4. Stand away from the unit outside the coverage
pattern.
5. Monitor the background noise for at least 3 min.
Readings should not deviate from the reference
level by more than ±0.15 VDC. For readings outside
these limits re-point the unit slightly, or mask the
affected zones.

Supervision Features
The LED shows a supervision trouble condition at
the detector and indicates the cause of the trouble
using coded pulses. The trouble signal activates
the trouble relay on Terminals 9 and 10. The relay
can be connected to a 24-hour zone. Table 2
shows LED responses to the supervision features.
The supervision features are:
PIR PIR operation is checked
electronically approximately
every 12 h. If the circuit fails,
the LED fl ashes four times and
activates the Trouble output.
Motion Verifi es the detector clearly
Monitor views the detection area.
Supervision
Select 30-day supervision
to monitor activity. If the
detector senses activity, the
timer resets. If no activity is
detected over 30 days, the
LED fl ashes two times and
activates the trouble output.
Refer to Section 7 DIP Switch
Confi guration.
Use Memory to count down
only during disarmed periods
(refer to Section 7 DIP Switch
Confi guration). The motion
monitor timer stops when
the control panel is placed
in the Armed (Night) Mode.
The timer resumes when
the control is placed in the
Disarmed (Day) Mode.
Trouble An alarm activation resets
Reset a motion monitor trouble
condition and an anti-mask
trouble condition. These
trouble conditions can also be
reset by temporarily removing
power. Wait 10 sec before
resetting the anti-mask timer.
