DS936 Ceiling Mount Passive Infrared

Intrusion Detection

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 be mounted on the surface,

or semi-flush directly to a ceiling or a standard octagonal electrical box.

I

NPUT POWER:

10 to 15 VDC non polarized; 15 mA @ 12 VDC.

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.)

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 mA maxi-

mum for DC resistive loads.

TAMPER:

Normally Closed tamper switch rated at 28 VDC, 125 mA.

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).

OPTIONS:

TC6000 Test Cord.

THINGS TO AVOID/REMEMBER

AVOID

• Direct hot and/or cold drafts • Windows • Small Animals

• Air Conditioning Outlets • Heat Sources • Direct Sunlight

REMEMBER

• Won’t detect through glass

• Best catch performance is across the pattern

• When using two or more detectors, cross the patterns for best coverage

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 3.7 m).

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 sys-

tems).

•

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 mounting screws, and

prestart the mounting screws.

•

Firmly mount the detector to the mounting

surface.

Recess Mounting With Octagonal Box:

•

To mount the DS936 to a 3 1/2 inch (89 mm) stan-

dard 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 discarded or saved for possible

future use.

•

Route wiring as necessary through the box and into

the wire entrance.

•

Mount the circuit board holder assembly to the box.

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 flush ring as a template, prepare

an opening 2-3/4" by 2-5/8" (70 x 67 mm) wide in the mounting surface.

•

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 wiring through the wire entrance.

•

Mount the detector to the ring using the supplied screws.

3.0 Wiring

•

Connect wiring as shown:

CAUTION:

APPLY POWER AFTER

ALL CONNECTIONS

HAVE BEEN MADE AND

INSPECTED.

•

Terminal 1 & 2 power limits are 10 to 15 VDC measured at the terminals. Use no smaller

than #22 AWG (0.8 mm) wire pair between the unit and the power source.

•

Connect a Normally Closed burglar alarm loop to terminals 3 & 4.

•

Connect a Normally Closed Tamper circuit to terminals 5 and 6. Tamper contacts

rated at 28 VDC, 0.125 amps.

NOTE:

Do not coil excess wiring inside unit.
