GENERAL INFORMATION
The 4275EX-SN Passive Infrared Motion Detector/VPlex Module
is designed for use only with control panels that support VPlex
(polling loop) technology. It is a tamper-protected wall-mounted
unit offering either wide-angle or long range/curtain (narrow)
area protection (2 separate easy-to-install mirrors come
supplied). Best coverage will be obtained if mounting is selected
such that the likely direction of intruder motion is across the
pattern.

INSTALLATION HINTS
Do not install where the detector is exposed to direct sunlight or
directly above strong sources of heat.
Make sure the detection area does not have obstructions
(curtains, screens, large pieces of furniture, plants, etc.) which
may block the pattern of coverage.
Avoid locating a unit in areas that contain objects likely to
produce a rapid change in temperature, such as central heating,
radiators or ducts (or heaters of any kind), air conditioners, open
flame, etc.
Install the detector at a height of approximately 7 feet (2.1m)
from floor. Do not mount on an unstable surface.
IMPORTANT: Avoid running alarm wiring close to telephone line
and alarm sounder wiring.
PROTECTION PATTERNS
Note: The protection patterns shown for wide-angle and long-
range mirrors can be modified to suit the needs of a particular
area by selective use of the masking strips supplied.

INSTALLATION
A. Changing from Wide-Angle to Long-Range Coverage:
1. Remove front cover by inserting a screwdriver blade in the
groove between cover and base (see Diagram 1), rotating
blade to override snap fit, and then lifting cover off.
2. Spread either or both plastic prongs holding the wide-angle
(35 ft/10.6m) mirror and remove the mirror (Diagram 2).
3. Insert one side of the narrow-angle (70 ft/21.3m) mirror
under a prong and snap the other side under the other
prong. Make sure that the mirror sides are squarely in
their corner rests and are held securely under the prongs.
Note: Mirror surface should be free of dirt, foreign matter
and fingerprints. Use a clean dry soft cloth to wipe mirror
surfaces, if required.
B. Normal Wall Mounting:
Note: For ANPI-approved installations, you cannot use
the mounting plate.
INSTALLATION INSTRUCTIONS
1. Remove the front cover as shown in Diagram 1.
2. Mount the wall plate to a firm vertical surface (flat on wall
or in corner). Position the plate so that field wiring is
centered in the rectangular slot at the top of the plate.
See Diagram 3 and Detail A.
3. Feed wiring through top access hole of detector (past foam
draft protector) but do not connect to terminal block yet.
4. Attach unit to wall plate by engaging all four hooks on the
plate into slots on the rear of the base and by pressing
downward (see Diagram 3). (Puncture the label on the
back of the base before installing.)
Note 1: The PIR is locked to the wall plate by a spring tab that
engages a square opening in the housing base (see Diagram 3).
The PIR can only be removed by cover removal, depression of
the tab from the inside with a small-blade screwdriver and then
sliding the PIR upward.
Note 2: If the PIR is to be mounted on a flat wall without its
mounting plate, install a 3mm screw into the wall at the planned
center (side-to-side) of the PIR, 1 inch (25mm) below the
planned top of the PIR. Leave 1/8" (3mm) clearance between the
screw head and the wall. Hook the PIR on the wall screw,
puncturing the label, and insert two screws into the mounting
areas on both sides of the mirror.
C. Inverted Mounting:
If small pets have access to the area protected by the detector,
this section pertains.
• The detector may be installed approximately 3 ft to 3- 1 / 2 ft (1m)
from the floor, provided furniture or other objects do not
obscure the pattern of protection.
• The detector and wall plate must be mounted inverted (the PIR
window at the top) with the wall p!ate tilted forward
(downward). Two self-adhesive rubber spacers have been
provided to aid in tilting the wall plate.
• It must be noted that although this procedure adjusts the PIR
zones so that small animals will not be detected, a crawling
intruder will ALSO go undetected.
• The spacers are to be used with the wall plate only when the
wide-angle mirror is in use.
Mounting flat on a wall:
Assemble the two spacers, one above the other, and affix the
combination to the rear of the plate, directly in line with the
single mounting hole located at the end of the plate opposite
to the wire entry access cutout.
Corner mounting:
1. Affix one of the spaces to the rear surface of each of the
two corner mount tabs on the wall plate, on the end
opposite to the wire entry access cutout.
2. Follow "Normal Mounting" steps 2, 3 and 4 described
previously, but orient the wall plate so that the wire entry
access cutout in the wall plate is positioned at the bottom.
3. When the detector is mounted in an inverted position, that
portion of the detector mirror that normally provides a
downward beam of protection will now provide a beam that
points upward. This will apply to both mirrors (long-range
and wide-angle). If possible, install the detector so that this
now upward-pointing beam is not directed at ceiling areas
that include heating or air conditioning ducts and vents or
lighting fixtures. If these IR sources cannot be avoided, the
upward-pointing segments of each mirror should be
masked to avoid the possibility of false alarms, as indicated
in the diagrams herein.
a. Remove the mirror from the detector, referring to a
previous page for information on mirror removal.
b. Mask the appropriate portion of each mirror as shown
in the diagrams below, using masking strips supplied.
Be sure to cover only the area shown.
WIDE AREA
c. Replace the mirror, making sure it is securely in
PATTERN
position before installing the cover.
WIDE ANGLE MIRROR
D. Optional Ceiling Mounting:
The versatility of this passive infrared motion detector permits
optional ceiling mounting, using the Long-Range ("Curtain")
mirror. This will provide a 15-20 ft (4.5-6m) forward-looking
"curtain" pattern as illustrated in Diagram 4.
The mounting procedure is the same as that for "Normal Wall
Mounting" except that the unit is ceiling mounted with the
window facing toward the detection area.
E. Mirror Masking:
The masking strips that have been supplied are designed for
application in one or more mirror segments to produce a
protection pattern that suits the particular requirements of the
protected area. Simply peel off the appropriate pressure-
sensitive adhesive strip(s) and apply over the desired mirror
segment(s). Individual masking strips have been provided for
3.5'
each of the mirror segments on the wide-angle mirror. Two strips
(1m)
10'
are provided for masking multiple segments of a long-range
(3m)
3.5'
(1m)
(curtain) mirror. Each mirror segment that is masked results in
the elimination of one zone of protection from the coverage

pattern. By masking appropriate segments of a mirror, you can

adjust the coverage to suit the area to be protected, or to

environmental disturbances that might reduce the PIR's stability
(a heater or other heat-producing object, for example).
Some examples of protection patterns that have been modified
by use of the masking strips have been provided. Also included
are application suggestions.
Note: The 9-segment wide-angle mirror is used in all examples
shown.
WIRING CONNECTIONS
Bring both polling loop wires through the wire access hole near
the terminal block and connect to screw terminals (see Diagram
5). OBSERVE POLARITY!
Pulse Count Option:
Each detector includes Pulse Count circuitry that provides stability
in adverse environments to minimize false alarms. This circuitry is
active when the switch #1 on the circuit board is set to the PULSE
COUNT position (see Diagram 5). The detector will then normally
signal an alarm within 3 to 4 steps, since the processing logic
requires more complex motion than just a momentary event.

For long-range applications where the detector is used to protect
narrow corridors, or where single protective zones are directed
through doorways or room openings, the pulse count option must
be disabled (see Diagram 5) to provide an instant alarm
response.
ADDRESS/SERIAL NO. ID
Note that this PIR's unique factory-assigned serial number can be
found on the bar code label on the left-hand corner of the PC board
(see Fig. 5).
This PIR's serial number can be enrolled by one of the following
methods:
1. Downloading (Zone Definition screen of V-LINK/Compass
software). Recommended for large installations and
installations where foot traffic cannot be controlled.
2. Enter manually at the "Input SN" prompt during manual zone
programming (see Important note below).
3. Enrolled by faulting the detector twice while at the "Input SN"
prompt during manual zone programming.
If programming manually, be sure that other polling loop sensors are
not activated so that they cannot send a signal to the control while
this PIR is being programmed (mask PIRs, don't open/close doors,
etc).
IMPORTANT
To be sure that other polling loop devices are not activated
when entering serial numbers, manually power the system
down, disconnect the polling loop at the control, power back up
again, and immediately enter the program mode. Remember to
re-connect the polling loop when programming is complete,
powering the system down first.
For specific programming information, see the Zone Programming
section of the control panel Installation Instructions.
TEST PROCEDURES
IMPORTANT: Two-minute warm-up is required after applying
power. Testing should be conducted with the protected area cleared
of all people. Disarm the protective system's control during the test
procedure to prevent reporting of unwanted alarms.
Walk-Test:
Place PULSE COUNT SW #1 to instant response, left, position.
Place WALK-TEST SWITCH #2 to walk-test, left, position (see
Diagram 5). Replace front cover and walk through protective
zones, observing that the detector's LED lights whenever motion
is detected.
The LED will only be active and should only be used during walk-
test procedures. When walk-test is completed, the walk-test
switch #2 must be set to the right position (DISABLED).
The panel may be able to control the walk-test function remotely. In
order for panel to do this, walk-test switch #2 must be set to the
right position (DISABLED).
Notes: In the instant response mode, the LED stays lit for
approximately 1 to 2 seconds after detecting motion. In
the event that switch #1 is placed in the pulse count, right,
position, the LED will illuminate for up to approximately 4
seconds when the detector verifies intrusion.
Make certain to test the unit in the mode it will be used.
For example, if pulse count is to be used, then the PIR
should be walk-tested with switch #1 set to pulse count,
right, position.
The absolute range of all Passive IR units is subject to variation
because of different types of clothing, backgrounds and ambient
temperature. For this reason, ensure that the most likely intruder
routes are well within the PlR's protective zones and that walk-
testing is carried out along the routes.
MAINTAINING PROPER OPERATION
In order to maintain the detector in proper working condition, it is
important that the following be observed by the user.
1. Power should be provided at all times. The unit's
control/communicator should have standby power available
for at least 4 hours of operation during emergencies.
2. Units should never be re-aimed or relocated without the
advice or assistance of the alarm service company.
3. The physical surroundings of the protected area
should not be changed. If furniture or stock is moved, or
air conditioning or additional heating is installed, the
system may have to be readjusted by the alarm service
company.
4. Walk-tests should be conducted frequently (at least
weekly) to confirm continued proper coverage by each
detector.
