Installation Instructions DS936 Ceiling Mount Passive Infrared Intrusion Detection

The DS936 is designed to be surface mounted directly on the ceiling or recess mounted to any 3 1/2 inch (88.9 mm) standard octagonal box. • Select a location that is most likely to intercept an intruder moving beneath and across the coverage pattern. Recommended mounting height is 7 ft. to 12 ft. (2.1 m to 3.7m). NOTE: Mounting surface should be solid and vibration free (e.g., Drop tiles should be secured if drop ceiling is used as an air return system for HVAC systems).

1.0 General Information
The DS936 is a Low Profile Ceiling Mount Passive Infrared Intrusion Detector, which uses alternate polarity pulse count. It uses a pointable Fresnel lens to provide up to 24 ft (7.2 m) of coverage and may bemounted on the surface, or semi-flush directly to a ceiling or a standard octagonal electrical box.
INPUT POWER: 10 to 15 VDC non polarized; 15 mA @ 12 VDC.

• Remove the top cover by gently prying it from the base with the blade of a screw driver. • Route wiring through the wire entrance located near the terminal strip. • Using the enclosure as a template, mark the location for the mountingscrews, and prestart the mounting screws. • Firmly mount the detector to the mounting surface.

STANDBY POWER: No internal standby battery. Unit is intended to be connected to
DC power sources capable of supplying standby power in the event primary power fails. 15 mA-H required for each hour of standby time needed.

MOUNTING HEIGHT: 7 to 12 ft. (2.1 to 3.7 m) on ceiling. COVERAGE: Provides 360°coverage pattern. (Coverage is approximately 2 times
the mounting height, see pattern drawing on page 2.)

Recess Mounting With Octagonal Box:
• To mount the DS936 to a 3 1/2 inch (89 mm) standard octagonal box, remove the circuit board holder from the base by prying holder tabs out with your thumbs and pushing the board holder assembly out with your index fingers. The base may be discardedor saved for possible future use. • Route wiring as necessary through the box and into the wire entrance.

PRY OUT HOLDER TABS

SENSITIVITY: Adjustable for Standard, Intermediate, or High. POINTABILITY: ±15° rotationally by moving lens. ALARM RELAY: Normally Closed operation and protected by a 4.7 ohm resistor in
series with the relay contact. Reed relay with contacts rated at 28 VDC, 125 mAmaximum for DC resistive loads.

OCTAGONAL BOX

TAMPER:

Normally Closed tamper switch rated at 28 VDC, 125 mA. • Mount the circuit board holder assembly to the box.

DS936

LED OPERATION: Dip Switch On/Off Selectable.
TEMPERATURE: The storage and operating temperature range is -20°F to +120°F (-29°C to +49°C). For UL Listed Requirements, the temperature range is+32° to +120°F (0° to +49°C).

BOARD HOLDER ASSEMBLY

Recess Mounting Without Electrical Box:
The DS936 may be recess mounted without the use of an octagonal box by using the supplied flush mount ring. • Remove the board holder assembly from the base by prying holder tabs out with your thumbs and push the board holder assembly out with your index fingers. • Using the inside cutout of the flushring as a template, prepare an opening 2-3/4" by 2-5/8" (70 x 67 mm) wide in the mounting surface.

OPTIONS: TC6000 Test Cord.

• Route wiring through opening and flush mount ring. • Place the flush mount ring over the opening and bend the support tabs into the opening and around the mounting surface so that the ring fits snug against the surface. • Route wiringthrough the wire entrance. • Mount the detector to the ring using the supplied screws.
