GENERAL INFORMATION
The Quest 2260SN is a Microwave/PIR polling loop motion detector
that offers unmatched levels of operation with the advanced
features listed below.
This detector is designed for use with control panels that support
serial number polling loop devices . It is not for use with panels that
support only DIP switch addressing.
Accu-Trak environmental test feature allows the installer to
•
check for environmental disturbances on both the PIR and
microwave channels at the same time.
Conditional Microwave Mode saves current in large installations.
•
Automatic adaptation to environmental disturbances.
•
Rejection of fluorescent light disturbance.
•
Continuous supervision of both PIR and microwave.
•
Advanced dual-slope temperature compensation assures optimal
•
detection.
Vertical and horizontal pattern adjustability.
•
Tampered front cover and back case.
•
This detector is shipped with its standard wide-angle lens installed
to provide coverage of 60 ft x 75 ft.
Optional swivel-mounting bracket is available under part number
998SB.

COVERAGE & LOCATION CONSIDERATIONS
Combined protective patterns are shown in Figure 1 for a nominal
mounting height of 7.5 ft (2.3m). The microwave detection pattern
shown in Figure 1 represents coverage in open space. In practical
application, when the detector is bounded by ceiling, floor, and
walls, reflections can occur.
SELECTING A MOUNTING LOCATION
The detector responds to changes in energy that occur when an
intruder moves into the combined protection pattern. Best coverage
will be obtained if the mounting site is selected so that the likely
direction of intruder motion is generally across the pattern and
angle s slight ly towar d the detector.

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 OFF when in the Accu-Trak 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.

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: Loosen (do not remove) the vertical
adjustment screw, slide the PC board down, then spread the
PCB holding tabs (see Figure 3), and remove the PC board.
3. Break out desired mounting and wire entry holes in the back
case. Refer to Figure 2. Knockout screw holes “A” in the back
case are for normal surface mounting on a wall. Knockout screw
holes “B” are for corner mounting.
Also break out the wire entry hole marked X in Figure 2. If
surface wiring is to be used, break out the section at the bottom
of the back case, and run the wiring up the wiring channel at
the back of the case to hole “X”.
If the back case tamper is to be used, use an additional screw
through hole C to secure the back case to the mounting surface.
4. Feed wiring (unpowered) coming from the wall through the wire
access hole near the top of the detector case back. If surface
wiring is used, use bottom access hole and use the wiring
channel in the case ba ck for routin g the wires.
5. Mount the base and reinstall the PC board.
6. Vertically align the PC board in accordance with Table 1
(Vertical Pattern Adjustment section below) before
tightening the vertical adjustment screw.
7. Refer to WIRING CONNECTIONS section before replacing cover.

WIRING CONNECTIONS
All wires shou ld have been fed thro ugh the wire access s lot at the
top of the detector base near the terminal block. Connect polling
loop wiring to the screw terminals as shown in Figure 3. Seal any
openings in the base with foam or RTV (not supplied) to prevent
drafts and insects from enteri ng t he un i t. Apply power only aft er all
connections have been made and are inspected.

HORIZONTAL PATTERN ADJUSTMENT
The protection pattern can be moved to the left or right by horizontal
adjustment of the lens, as follows.
1. Remove the front cover as indicated in step 1 of the MOUNTING
section.
2. Remove the lens holder in the front cover by squeezing the two outer
sides of the holder together, releasing it from the side clips (see
Figure 4). Then pull the holder out, exposing the lens.
3. Slide the lens slightly to the left or right to change the horizontal
pattern as desired.
4. Reinstall the lens holder. It should snap firmly in place beneath the
holding tabs on each side.
5. Replace the front cover.
IMPORTANT: After any adjustment, conduct a walk test to ensure
proper coverage of the area to be protected. See the
Test Procedures section.
VERTICAL PATTERN ADJUSTMENT
The protection pattern can be moved up or down by vertical
adjustment of the lens as follows.
1. Remove the front cover as indicated in step 1 of the
MOUNTING section.
2. Loosen the PCB screw on the lower right of the board (s ee Fig.
3), and slide the board into the appropriate position, using the
scale to the right of the screw. Use Table 1 which shows the
proper setting for the de s ired range.
