Step 2

Mount the sensor.

Break out the mounting/wiring knockouts and

protect.

mount the sensor in an appropriate location.

An ideal location meets the following objectives:

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

fluorescent lights, and heating/cooling

sources.

• Does not directly face windows.

• Avoids close proximity to moving machinery,

containing pets.

• See Special Instructions for installations

NOTE: maximum range is obtained at a

Walk-test the sensor.

After returning the PCB to the rear hous-

ing, reassemble the sensor housing. Ap-

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.

SPECIAL INSTRUCTIONS FOR INSTALLATIONS CONTAINING PETS

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

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

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.

DETECTION PATTERNS

be followed:

climbing on furniture, boxes or other objects.

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

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

• 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.
