DS9370 TriTech Ceiling Mount

PIR/ Microwave Intrusion Detector

1.0 Specifications

• Dimensions (HxDia): 3.5 in. x 7 in. (8.9 cm x 17.8 cm)

• Coverage: 360° by 70 ft. (21.3 m) diameter

coverage when mounted on 12 to 25 ft.

(3.7 to 7.6 m) high ceilings. A coverage

area of 40 ft. (12.2 m) is available when

mounted at 8 ft. (2.4 m) and a coverage

of 50 ft. (15.2 m) is available when

mounted at 10 ft. (3 m). The pattern

consists of 69 zones grouped into 21

barriers. Each barrier is 35 ft. (10.7 m)

long and 5 ft. (1.5 m) wide at 35 ft. (10.7

m). The barriers are divided into 3 groups

of 7 barriers, each of which has a vertical

adjustment for custom coverage.

• Input Power: 9.0 to 15.0 VDC; 29 mA standby, 39 mA

in alarm with LEDs enabled, and 49 mA

max current. Use only an Approved

Limited Power Source.

• Standby Power: There is no internal standby battery.

29 mAh is required for each hour of

standby time needed. For UL Listed

Requirements, four hours of standby

current (116 mAh) is required. Standby

power must be provided by an Approved

Limited Power Source.

• Sensitivity: Low/High settings.

• Alarm Relay: Silent-operating Form “C” relay. Contacts

rated 125 mA, 28 VDC, 3 watts

maximum for DC resistive loads. The

contacts transfer on alarm for a period of

4 seconds. Some countries require the

relay to be connected to a SELV

(Safety Extra-Low Voltage) circuit only.

Do not use with capacitive or inductive

loads.

• Tamper: Normally Closed (with cover in place)

tamper switch. A wall (base) tamper is

included. Contacts rated at 28 VDC, 125

mA, 3 watts maximum. Some countries

require the switch to be connected to a

SELV (Safety Extra-Low Voltage) circuit

only. Connect tamper circuit to a 24-hour

protection circuit.

• Temperature Range: The storage and operating range is -40°

to +120°F (-40° to +49°C). For UL Listed

Requirements, the range is +32° to

+120°F (0° to +49°C).

• Microwave Frequencies:

DS9370:10.525 GHz

DS9370-C: 10.588 GHz

(Export only. Not UL Listed)

• Countries of Intended Use: These products are intended for use

in the following countries within the European Union and in other

countries outside of the European Union:

• DS9370:Austria, Belgium, Denmark, Finland, Greece,

Luxembourg, Netherlands, Norway, Spain, Sweden.

• DS9370-C: United Kingdom, Ireland, France.

• US Patent Numbers: This detector is protected by one or

more of the following: #4,660,024; 4,764,755; 5,077,548;

5,208,567; 5,262,783; and 5,450,062. Other patents pending.

• Compliance: 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.

Changes or modifications not expressly approved by Detection

Systems, Inc. can void the user’s authority to operate the

equipment.

2.0 Installation Considerations

• Never install the detector in an environment that causes an

alarm condition in one technology. Good installations start with

the LED OFF when there is no target motion. It should never be

left to operate with the tri-color LED in a constant or intermittent

green, yellow, or red condition.

NOTE: Microwave energy will pass through glass and most

common non-metallic construction walls.

• Avoid installations where rotating machines (e.g. ceiling fans)

are normally in operation within the coverage pattern. Point the

unit away from glass exposed to the outdoors and objects that

may change temperature rapidly. Avoid mounting the unit within

1 ft. (0.3 m) of any fluorescent light fixture.

Note: The PIR detector will react to objects rapidly changing

temperature within its field-of-view.

• Eliminate interference from nearby outside sources.

3.0 Mounting

• Select a location likely to intercept an intruder moving across

the coverage pattern. Recommended mounting height range is

12 to 25 feet (3.7 to 7.6 m). A coverage area of 40-70 ft. (12.2-

21.3 m) is available when mounted between 8-12 ft. (2.4-3.7 m).

• The surface should be solid and vibration-free. (i.e. drop tiles

should be secured if the area above the tiles is used as an air

return for HVAC systems).

• To open the detector, locate the arrow on the cover of the

detector . Turn a screwdriver in the recess between the

cover and the base . One side of the cover will remain

attached to the base of the detector.

• If necessary, you may remove the base from the cover by pressing the two cover release tabs inward while lifting the base away from the cover. 5.0 Wiring CAUTION Note: Only apply power after all connections have been made and inspected. Do not coil excess wiring inside detector. Input power must use only an Approved Limited Power Source. Some countries require that the Alarm and Tamper Contacts be connected to a SELV (Safety Extra-Low Voltage) circuit only.

7.2 LED On/Off Pins The ON position allows operation of the tri-color LED. If LED indication is not desired after setup and walk tests are completed, place in the OFF position. 7.3 Microwave Adjustment Note: It is important to wait 1 minute after removing/replacing the cover so the microwave portion of the detector can settle, and to wait at least 5 seconds between the following walk testing procedures. • The tri-color LED should be OFF before walk testing.

11.0 Optical Module Adjustment • The PIR zones of the DS9370 are divided into three groups. Each of these 3 groups can be independently adjusted vertically to provide the best coverage within a room. MAX PIR Signal Gain - Only two coverage patterns are shown for clarity. • NO C NC T T M PIR vertical adjustment knobs Use the following chart to adjust the optical modules based on the mounting height of the detector.
