Installation Considerations
Not suitable for outdoor use (2-1 ).
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 outside traffic. Microwave energy
passes through non-metallic walls.
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).
Point away from rotating machines (fans) (2-6).
Mount the detector on a solid and vibration free surface.
Secure drop-ceiling tiles, if the area above the tiles is
used as an air return for heating, ventilating, and air
conditioning (HVAC) systems.
Avoid mounting the detector within 1 ft (0.3 m) of any
fluorescent light fixtures.
warning!
Apply power only after all connections are made and
inspected. Do not coil excess wiring inside detector.

Optical Module Adjustment
The PIR zones of the detector are divided into three
groups. Use the PIR adjustment knobs (10-1) to
independently adjust each group vertically to provide
the best coverage within a room. Two coverage
patterns are shown (10-2).
If targeted coverage is required for part of the area,
adjust the optical modules for the correct coverage.
For example (10-3): The detector is mounted 12 ft
(3.7 m) above the floor. The distance to one wall is 20 ft
(6.1 m) and 35 ft (10.7 m) to the opposite wall. Using
the
Optical Module Adjustments Table (10-4),
set the
optical module for the 20 ft (6.1 m) range to "D" and the
optical module for the 35 ft (10.7 m) to "I". Refer to
(10-5) for the maximum range and (10-6) for the
mounting height.
Note: The range shown in (10-4) is the distance from
the detector to the outside edge of the coverage
pattern.
Two coverage patterns are shown (10-3).

There is no internal standby battery. An external standby battery capacity of 29 mAh is required for each hour of standby time needed. For UL, 4 h (116 mAh)
must be provided by the control unit. The products are intended to be powered by a power-limited output of a UL/cUL Listed Burglar Alarm control unit, or via
a Listed UL603/ULC-S318 Class 2 power limited power supply, capable of 4 hours of standby power. Check standby battery annually.

Silent-operating Form "C" relay. Contacts rated 100 mA, 28 VDC, 2.8 W maximum for DC-resistive loads. The contacts transfer on alarm for a period of 4
sec. Note: Do not use with capacitive or inductive loads.
Normally closed (NC), with cover on. A ceiling tamper is included for surface mounting. Contacts rated at 28 VDC, 100 mA, 3 W maximum.
Microwave: The complete circuit operation of this subsystem is checked approximately every 4 h.
PIR: The detector defaults to PIR technology protection if the microwave subsystem fails. The detector indicates an alarm using the green LED only and
activates the alarm relay.

Coverage Pattern Masking
1. Select a mounting location. Mount the sensor where an intruder is most likely to cross the coverage pattern
(5-1).
2. Mount the detector 8 ft to 20 ft (2,4 m to 6.1 m) above the floor, 12 ft (3.7 m) recommended (5-2).
3. To open the detector, locate the arrow (5-3) on the cover of the detector. Insert a flat head screwdriver in the
recess (5-4) between the cover and the base and twist. One side of the cover remains attached to the base of
the detector.
4 Optional: Remove the cover from the base. Grasp the top of the cover with one hand while holding the base
with the other (5-5).
5. Gently push the cover to one side (5-6) while twisting the cover back and away from the base (5-7).
Note: Ensure all wiring is de-energized before routing.
6. Route wiring as necessary to the rear of the base and through the center hole (5-8) or wire entrance for sur-
face mounting (5-9).
To reduce the detector's coverage area, use the masks
provided. The masking kit contains two 120
°
(4-1) and
two 90
°
(4-2) masks. You can mask:
- go• (4-6)
Note: Do not mount on removable ceiling tiles unless a sandwich is made of the base, ceiling tile, and a back plate
behind the tile.

7. Firmly mount the base using the mounting holes (5-10, 5-11) and one of these options:
Depending on local regulations, mount the base directly on the surface using anchors, mollies, or wing
nuts.
Mount the detector on an electrical box.
Connect the detector directly to short lengths of electro-magnetic tubing (EMT), 0.5 in. (1.27) cm (short
enough to avoid movement of the detector). Use the wire entrance for the EMT (5-8).
Note: Use the curved mounting slots (5-11) to rotate the detector up to 60
°
to establish the best coverage.
8. If a ceiling tamper is needed, remove the tamper post (5-12) by tapping it gently with a hammer to detach it
from the three tabs.
9. Mount the post to the ceiling using the #8 screw provided (5-13).
10. Attach the cover if removed, and close it.
11. Secure the entire assembly with the supplied anti-vandal screw (5-14 ).
12.Use the cable ties (5-15) for strain relief.

Low (8-2) Recommended setting for most installations. Tolerates environmental
extremes.
Note: The detector is shipoed in Low Sensitivitv mode.
High (8-3) Use this setting if more sensitivity is needed.
Note: This setting is more sensitive to environmental changes that can cause
false alarms.

Walk Test
Note: Ensure the LED jumper is set to on (8-5).
Note: To avoid false alarms, set the microwave range
(11-1) to its minimum setting before starting the Walk
Test.
1. Wait at least 2 minutes after power up to start the
Walk Test.
The blue LEDs flashes 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 (11-2). The LED lights at the outside edge of
the coverage range.
The red LED lights, identifying the PIR pattern edge.
The yellow LED lights, identifying the microwave
pattern edge.
The blue LED indicates alarms in both the micro
wave and PIR mode.
4. Repeat Step 3 from different directions until you
adequately verify the coverage pattern.
5. If the required microwave coverage is not achieved,
increase the microwave adjustment (11-1) by turning
it clockwise slightly. Wait 1 min after adjusting the
microwave range before continuing the Walk Test.
'\..
Note: Do not adjust the microwave range higher than
needed.
Product must be walk tested at least once each year.
