The AP633 and AP643 offer the detection of motion for
infrared targets in selectable ranges extending 40 ft., 80 ft.
and 200 ft.(12 m, 24 m, and 60 m). The detector’s sensitivity
may be programmed to suit most environmental applications. Aritech’s traditional viewing angle selection (mirror
blocking) allows the installer to select and delete any portion
of the coverage pattern to customize the optical performance
of the unit. In addition, the mounting plate of the sensor is
equipped with precise adjusting screws to allow the installer
to alter the horizontal viewing point as much as 2 degrees to
the left or right, above or below the unit. These features
combine to make this passive infrared sensor the most stable
detector available for commercial and industrial installation
needs in the security industry today. The more sophisticated
model AP643 enhances standard operation with options
such as alarm memory, unit to unit double check, eye to eye
check, and first in alarm indication as well as remote control
of the walk test mode.

MOUNTING TIPS
SENSOR HOOKUP
• This sensor is for interior applications only.
Do not mount outside.
• Do not block the viewing angle of the sensor.
• Mount this and all passive infrared sensors so that would
be intruders will cross the pattern of detection at 90°
(or as close to 90° as possible).
• Seal all openings and cable entries.
• When mounting sensor on masonry surfaces use appropriate moisture barrier.
• Use of the vertical adjustment screw may result in a
reduction of range.
MOUNTING THE SENSOR
The ideal mounting height for this sensor is 6 ft. to 10 ft.(1.8
m to 3.0 m). Loosen the retaining screw and lift the front
cover off of the unit. Using an awl or similar punch type
device, remove the necessary knockouts and create a path for
the cables to enter the backplate. Remove only those
knockouts which you plan to use. Pull cable through the
entries and level the backplate on the wall. Mark the screw
holes and insert 8-32 x 2 inch screws and tighten until
secure. Be careful not to over-tighten the backplate as you
may wish to adjust the viewing angle after walk testing. It is
important to leave a 1/2 inch clearance space between the top
of the sensor and any surfaces above it (i.e. ceiling, shelves
or cabinets, etc.). This will allow the cover to be replaced
with ease.
Both units are equipped with a Form C alarm initiation
circuit (Terminals 3,4, and 5) and a closed loop tamper
circuit (Terminals 6 and 7). The installer may wire these
circuits in series if desired. If the control panel requires class
B supervision, the spare terminal (# 8) may be used to
anchor the EOL device. This allows the installer to place the
EOL device in the sensor without the use of splice connectors. Some of the advanced detection features of the AP643
(discussed later) require an additional switched voltage from
the control. If the protective loop and the control panel
power supply share a common negative, both may use the
same conductor. This will free up a single conductor for use
in one of the advanced features.
Detectors must be connected to a UL listed control or
power supply which will provide a minimum of four
hours standby power.

Notes:
1. The AP633 uses pin jumper D to enable/disable the walk
test LED. The pin cover connects to both pins to enable
this feature.
2. This unit uses a 33Ω (ohm) current limiting resistor for
transient protection on the protective loop. It is important
to consider this value when calculating loop resistance.

SENSITIVITY
The sensor uses a unique signal processing method known as
Dynamic Data Discrimination. “4D” allows the sensor to
analyze the size and shape of a waveform produced in the
detector and determine whether the signal is generated by an
intruder or an environmental source. The sensor has three
field changeable settings of sensitivity for “4D”: High
Sensitivity, Increased Sensitivity and Standard Sensitivity.
The installer may select standard sensitivity by moving the
pin connector of jumper A to cover the lower two (2) of the
three (3) pins. High sensitivity is selected by inserting the pin
connector in such a way that it only makes contact with one
of the three (3) pins of jumper set A. Increased sensitivity is
selected by inserting the pin connector of jumper set A so
that the upper two (2) pins are covered.
Standard Sensitivity should be selected for normal and all
40-foot-wide angle applications. For use with patterns E,
G, and H only.
High Sensitivity should only be used in hazard free, highsecurity applications. For use with patterns A through L.
Increased Sensitivity should be used in 80-foot-wide angleareas, 40-foot curtain only or long range applications. For
use with patterns A through L.
ZONE LOCATION TESTING
This sensor is equipped with a test feature which goes
beyond walk testing and allows the installer to identify
exactly each zone of coverage. This advantage allows the
installer to avoid splitting a zone of coverage between two
areas of dissimilar background infrared energy levels, such
as a metal door and a freezer. By inserting the pin connector
so that both of the pins in jumper set B are covered, the zone
location test mode is active. After activating this mode, walk
without stopping across the coverage pattern and observe the
sensor. Each time the green LED illuminates, you enter a
zone. If the green LED goes out, you are in the center of a
zone (between two pyroelectric elements) or you are between
two zones. By connecting the armed output of the control
panel (+12 VDC) to Terminal 9 of all detectors connected on
this run (up to 40 units), the LED will latch in alarm any and
all sensors which were activated during the armed period.
After determining all zone locations, return to the normal
mode by inserting the pin connector so that the two pins of
jumper set B are not connected.
ALARM MEMORY SETTING–AP643
By connecting the armed output of the control panel
(+12 VDC) to Terminal 9 of all detectors connected on this
run (up to 40 units), the LED will latch in alarm any and all
sensors which were activated during the armed period.
The jumper from Terminal 2 to Terminal 10 must be
removed after walk test to enable this feature.
FIRST TO ALARM SIGNAL–AP643
An added feature to the Alarm Memory Setting is the First to
Alarm Signal. By connecting Terminal 10 of the first sensor
on the run to Terminal 10 of subsequent sensors, as well as
wiring described in Alarm Memory Setting, the first unit
activated in an armed cycle will indicate activation by
flashing. Subsequently activated sensors will annunciate by a
solid indication on the walk test LED.
The jumper from Terminal 2 to Terminal 10 must be
removed after walk test to enable this feature.

DOUBLE CHECKER MODE–AP643
The Double Checker Mode is a special discrimination
method in which a valid alarm signal will be given only
when a minimum of 2 detectors have recognized an event or
when the same sensor detects 2 events within a specific time
frame. This feature will allow the installer to station 2 or
more detectors in a premises along a projected path of
intrusion. Should the sensors see any 2 events within a 2
minute time period then the violated sensors will activate
the control panel. To select this mode of operation, insert
the pin connector of jumper set C so that both pins are
disconnected. (Wire same as First to Alarm Indication).
Not for use in UL installations.
Settings: Increased sensitivity, walk test off, eye to eye
not cut, jumper 2 to 10 removed.
EYE TO EYE CHECKER–AP643
In extremely hazardous environments or installations
requiring absolute accuracy of an alarm, dual detector
verification may be desired. By cutting a special compo-
nent on the sensor and aligning the viewing angle of 2
sensors so that they view a common area, the sensors will
only activate the control if both share a violation within a
short time frame (10 sec.). This offers an unparalleled
accuracy of detection. An intruder must violate the coverage
pattern that the 2 sensors share in common. (Wire same as
First to Alarm Indication).
For use in UL installations, protection patterns must
overlap and provide detection by both sensors per UL
standard walk test procedures.
Settings: High or increased sensitivity, walk test off,
double checker off, eye to eye on.
