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.

Trouble Output. Upon supervision failure, this open
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.
