INSTALLATION HINTS

The detector is remarkably resistant to false alarm hazards,

but the following recommendations should be observed.

• Never install the detector in an environment that causes a

disturbance in one technology. Good installations start

with

both

LEDs

environmental test mode and there is no target motion.

• Do not mount on an unstable surface. Locate the unit on a

sturdy inside wall whenever possible. Avoid sources of

vibration such as loose fitting doors and walls that shake

when heavy traffic exists.

• Do not install on or close to metal structures such as metal

door frames, shelves, etc.

• Do not include space heaters in the protective pattern

whenever possible, to avoid rapid temperature changes

and vibrations from fans.

• ALL microwave transmission penetrates most building

materials (except metal, which reflects transmission).

Moving objects outside of the protected area may be

detected unless the microwave sensitivity control is kept at

as low a setting as possible, to minimize penetration.

• Make sure the detection area does not have obstructions

(curtains, screens, large pieces of furniture, plants, etc.)

that may block the PIR portion of the coverage pattern.

MOUNTING

Mount the unit to a firm vertical surface. The wall wiring hole

should be no more than 5/16" (8mm) diameter.

1. Remove the front cover by twisting a screwdriver blade in

the groove between cover and base at the bottom edge of

the case and then lifting the cover off.

2. Remove the circuit board from the base. Loosen the

vertical adjustment screw, slide the circuit board up and

spread the PCB holding tabs as shown in Figure 3.

3. Break out desired mounting and entry holes. Refer to

Figure 2. Knockout holes "A" in the base are for normal

surface mounting on a wall. Knockout holes "B" are for

corner mounting. Also break out the wire entry hole

marked X in Figure 2.

4. Feed wiring (unpowered) coming from the wall through the

wire access hole near the top of the detector base. Use the

wiring channel on the back to assist with routing.

5. Mount the base and reinstall the PC board.

6. Vertically align PCB before tightening screw.

7. Refer to WIRING CONNECTIONS section before

replacing the cover.

The QUEST 2235 and QUEST 2235C will provide reasonable

protection from nuisance alarms caused by the following

sources:

Accu-Trak

• A dog up to 100 pounds.

• Two dogs, up to 60 pounds each.

• Up to 10 cats.

• Multiple small rodents, such as rats.

• Random flying birds.

To take full advantage of the QUEST's next-generation

performance for pet immunity, the following guidelines should

be followed:

• Mount the center of the detector 7.5 feet high and adjust

the PCB to POSITION ZERO.

• Set the sensor sensitivity for standard (STD).

• 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 an animal.

• Adjust

acceptable coverage for the room in which the detector

is installed. Never install with the microwave range

exceeding 35 feet.

WIRING CONNECTIONS

Bring all wires through the wire access slot at the top of the

detector base near the terminal block and connect to the screw

terminal. See Figure 3 for wiring details. Seal any openings in

the base with foam or RTV (not supplied) to prevent drafts and

insects from entering the unit. Apply power only after all

connections have been made and are inspected.

collector output will go low (requires 1000-ohm pull-up

resistor). Use shielded wire for UL installations.

REMOTE LED DISABLE

A separate terminal pin is provided on the PCB that can be

used to remotely control the LED. (See Figure 3.) If a 7-16VDC

signal is applied to the terminal, all LED functions will be

disabled, including alarm, Accu-Trak environmental test

mode, and supervision failures. To remotely enable the LED

by removing the 7-16VDC signal, DIP Switch #3 must be set

to OFF (LED enable).

ADJUSTMENTS AND SELECTIONS

Microwave Sensitivity Control: Turn the potentiometer

clockwise to increase sensitivity.
