Honeywell DUAL TEC DT-7235 Installation guide

Brand: Honeywell

Model: DUAL TEC DT-7235

Category: Motion detectors

Type: Installation guide

Honeywell DUAL TEC DT-7235 is a motion sensor that utilizes both passive infrared (PIR) and microwave technology to detect movement. It is designed for indoor use and can be mounted on a wall or ceiling. The DT-7235 has a range of up to 35 feet (11 meters) and a field of view of 180 degrees. It is also pet-immune, meaning that it will not be triggered by small animals weighing less than 45 pounds. The DT-7235 is a reliable and effective motion sensor that can be used for a variety of applications, including home security, commercial security, and industrial automation.

DT-7235/DT-7235T DUAL TEC® Motion Sensor Installation Instructions

Step 1

Separate the sensor housings and remove

Printed Circuit Board (PCB).

Use a small screwdriver to unfasten the hous-

ing latch and separate the sensor housings.

Push outward on the PCB latch to lift the PCB

out of the housing.

Step 3

Wire the sensor.

Observing the proper polarity, wire the unit as

shown in the illustration below, use 1.02 to 0.64 mm

(18 to 22 AWG) wire.

Step 2

Mount the sensor.

Break out the mounting/wiring knockouts and

mount the sensor in an appropriate location.

An ideal location meets the following objectives:

• Allows a clear line-of-sight to all areas to

protect.

• Does not directly face windows.

• Avoids close proximity to moving machinery,

fluorescent lights, and heating/cooling

sources.

•See Special Instructions for installations

containing pets.

NOTE: maximum range is obtained at a

mounting height of 2.3 m (7’6”).

Step 4

Walk-test the sensor.

After returning the PCB to the rear hous-

ing, reassemble the sensor housing. Ap-

ply power to the sensor and begin walk-

test when the red LED is off.

Walk across the detection area at the

ranges to be covered. The red LED should

indicate an alarm condition after 2 to 4 nor-

mal steps. When there is no motion in the

detection area the LED should be off.

MICROWAVE SUPERVISION

If the microwave technology stops sending or receiving signals,

the sensor locks into an alarm condition. The LED at the sensor,

however, does not light.

If the microwave regains its signal, the sensor (and LED) returns

to normal operation.

NOTE: The DT-7235/7235T sensors should be tested at least

once each year to ensure proper operation.

DT-7235/DT-7235T DUAL TEC® Motion Sensor Supplemental Information

* Look-down fingers are enabled only when look-

down mask is removed, see Step 1.

SPECIAL INSTRUCTIONS FOR INSTALLATIONS CONTAINING PETS

To take full advantage of the pet immunity the following guidelines should

be followed:

• Mount the center of the detector 7’6” (2.3 m) high.

• Ensure that the look-down mask is in place (see Step 1).

• Mount where animals cannot come within six feet of the detector by

climbing on furniture, boxes or other objects.

• Do not aim the detector at stairways that can be climbed by animals.

Notes:

This sensor will provide immunity to false alarms for an individual animal

or a group of animals whose total weight is equal to or less than 45.36 kg

(100 lbs).

The pet immunity function of this sensor has not been evaluated by UL.
