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 traffi c. 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
fl uorescent light fi xtures.
Warning!
Apply power only after all connections are made and
inspected. Do not coil excess wiring inside detector.
SELV
- Some countries require the relay to be connected to
a Safety Extra-Low Voltage (SELV) circuit only.
- Some countries require the tamper switch to be
connected to a SELV circuit only. Connect tamper
circuit to a 24-hour protection circuit.

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 fl oor. 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).

Specifi cations
Dimensions: Height: 3.5 in. (8.9 cm)
Diameter: 7 in. (17.8 cm)
Versions: DS9370: Pearl white
DS9371: Black (only for use in the U.S.)
Coverage: 360° by 70 ft (21 m) diameter coverage when mounted on 12 ft (3.7 m) to 25 ft (7.6 m) high ceilings. A coverage area diameter of 40 ft (12 m) is available
when mounted at 8 ft (2.4 m) and a 50 ft (15 m) diameter at a height of 10 ft (3 m). The pattern consists of 69 zones grouped into 3 sets of 23 zones. Each
set covers one-third of the 360° coverage pattern. Each set also has a vertical adjustment for precise pattern alignment.
Input Power: 9 VDC to 15 VDC, 19 mA standby, 39 mA in alarm with LEDs enabled, and 39 mA maximum current. Use only a Listed limited-power source.
Standby Power: 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 Listed product
installations, 4 h (116 mAh) must be provided by the control unit or a UL Listed limited-power source.
Sensitivity: Low and high settings.
Alarm Relay: Silent-operating Form "C" relay. Contacts rated 125 mA, 28 VDC, 3 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.
Tamper: Tamper switch is normally closed (NC), with cover on. A ceiling tamper is included for surface mounting. Contacts rated at 28 VDC, 125 mA, 3 W
maximum.
Supervision Microwave: The complete circuit operation of this subsystem is checked approximately every 4 h.
Features:
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.
Temperature The storage and operating range is –40
Range: (–40°C to +49°C).
For UL Listed installations, the temperature range is
(+32 o F to +120 o F (0 o C to +49
Microwave 10.525 GHz
Frequencies: DS9370-C: 10.588 GHz (Export only, not UL Listed.)

Coverage Pattern Masking
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:
- 90° (4-6)
- 120° (4-3)
- 180° (4-4)
- 210° (4-7)
- 240° (4-5)
- 330°
Place the masks on the outside of the detector. Do not
open the detector and place the masks on the inside.
Note: Masking does not affect the microwave.

Other Features
Memory, Night Mode, and Walk Test need a control
voltage on Terminal 8 to activate these features (refer to
Table 1). The control voltage must be between 6 VDC
and 18 VDC.
Use a supply voltage to apply a control voltage to
Terminal 8 (7-1).
Or, use a control panel or external DC power supply as
control voltage (7-2):
- +6 VDC to +18 VDC = On (switch closed)
- 0 VDC = Off (switch open)
Day Mode Disables the alarm memory and
allows 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.
Note: The LED jumper must be in the
On position (8-5).
Night Mode Enables the alarm memory and
disables the LED operation.
Remote Walk Remotely enable the LED operation
Test from Terminal M for walk testing. Use
this feature when the LED jumper is in
the Off position (8-6).

Mounting
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 12 ft to 25 ft (3.7 m to 7.6 m) above the fl oor (5-2).
3. To open the detector, locate the arrow (5-3) on the cover of the detector. Insert a fl at 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).
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.

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 red LEDs fl ashes 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.

adequately verify the coverage pattern.
5. If the required microwave coverage is not achieved,
increase the microwave adjustment (11-1) by turning
On 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

Note: The detector is shipped in Low Sensitivity mode.
Note: This setting is more sensitive to environmental changes that can cause
false alarms.
