GENERAL INFORMATION
This passive infrared motion detector is a ceiling-mounted unit
employing a 360° , 31-zone Fresnel lens and offering an efficient
protection pattern for commercial and residential applications.
The detector senses sudden and slight changes in temperature
within the area of detection; thus, when an intruder crosses or
enters any zone, the resulting change in infrared energy is
detected for alarm reporting. Best coverage will be obtained if
the PIR is mounted such that the likely direction of intruder
motion is in the direction shown in Figure 1.
The Detector features installer-selectable Alternate Polarity
Pulse Count, which provides protection against false alarms,
and an LED enable/disable feature (installer-selectable).
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.) that
may block the pattern of coverage.
• Avoid locating a detector 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.
• Do not mount on an unstable surface.
Important: Avoid running alarm wiring close to heavy-duty
electrical power cables.

INSTALLING AND WIRING THE PIR
The ceiling on which the PIR is to be mounted must be firm and
vibration-free.
1. Select a location that will provide the coverage desired.
Wiring (from the control, etc.) to be connected to the PIR
should be brought to this location. The ceiling wiring hole
should be no more than 5/16" (8mm) in diameter.
2. Remove the cover from the PIR by pressing it in gently and
turning it counterclockwise (to the left). To replace the cover,
align the tabs on the cover's edge with the notches on the
base's rim, press the cover gently in, and turn it clockwise (to
the right).
Installation Instructions
3. Break out one of the two knockouts that have been
provided for wire access (see Figure 3), and pass the wires
into the base of the PIR. Caution: Be certain that wires do not
obstruct the detector's field of view.
4. Connect all wires to the screw terminals (see Figure 3 for
wiring details). Seal all openings in the base with foam or RTV
(not supplied) to prevent drafts or insects from entering the
unit.
5. For walk-test purposes, initially set the LED to "on" (jumper
removed), and set Pulse Count "off" (jumper removed).
6. Mount the PIR base to the ceiling with two screws, using the
screw holes provided in the base of the PIR.
Important Note: Optimum mounting orientation is shown in
Figure 1. Mount the PIR in such a manner that the likely path of
an intruder is in the direction shown. This will ensure maximum
effectiveness of the Alternate Polarity feature.

FIELDS (INCLUDING
walk-test) by removing the LED enable/disable plug (see Figure 3
THE CENTER ZONE)
for location). To prevent the loss of the plug, we suggest you
install it on one pin when the plug is not in use. When the walk-
test is completed, the LED may be disabled, if desired (plug in
place).
The LED may also be controlled from a remote location, as
follows:
Remove the LED enable/disable plug. Connect a switched line to
the upper pin (#1) of the two LED pins that can be grounded or
opened (see Figure 2). Grounding pin #1 will disable the LED.
Disconnecting it from ground will enable the LED.

TAMPER SWITCH
This PIR is equipped with a cover tamper switch. With cover
on, the switch is closed; when cover is removed, the switch
opens. The tamper terminals (see Figure 3) should be
connected to the control panel's tamper loop.
PULSE COUNT OPTION
Each detector includes Pulse Count circuitry that is designed
to provide stability in adverse environments to minimize false
alarms. Two-event pulse count is provided by positioning the
jumper plug across the pulse count pins (see Figure 3 for
location). To select one-event pulse count (instant response),
remove the jumper plug. When programmed for 2-event pulse
count, the detector will signal an alarm within 3 or 4 steps,
since the processing logic requires more complex motion than
just a momentary event. When the detector verifies an
intrusion, the LED will light and the alarm relay contacts will
transfer, both conditions lasting for approximately 1 to 3
seconds (dependent upon signal strength).
To prevent the loss of the plug, we suggest you install it on one
pin when the plug is not in use.

TEST PROCEDURES
Important: Two-minute warm-up time 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
1. Pulse Count in the PIR must be "OFF" (jumper plug
removed) to provide instant response. The Alarm LED must
be enabled at this time (LED jumper plug removed).
2. With the cover installed on the PIR, walk through the
protective zones, observing that the PIR's LED lights
whenever motion is detected (the LED serves as a walk-test
indicator during this procedure).
Note: With pulse count "OFF" (instant), the LED stays lit (and
the alarm relay contacts remain open) for approximately 1 to 3
seconds after detecting motion.
3. If pulse count is to be used in this installation, install the
pulse count jumper plug on the pulse count pins, and repeat
the walk test procedure. With pulse count "ON," the LED
serves as an alarm indicator.
The absolute range of all PIR 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 PIR's protective zones and
that walk-testing is carried out along these routes.
After the walk-test is complete, the LED may be disabled if
desired (LED enable/disable plug installed).
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. Loss of power to
the unit will result in the alarm contacts reverting to an alarm
state. The unit's DC source should have standby power
available for at least 4 hours of operation during
emergencies.
2. Units should never be 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.
TROUBLESHOOTING
INTERMITTENT ALARM (LED OPERATIVE)
Probable Causes:
A. Rapid temperature change. Check for electric or gas
heaters, open flames, electric arcs, etc..
Remedy: Locate
source
and
necessary.
B. Drafts causing drapes, light fixtures, display material to
move.
Remedy: Eliminate source of motion.
INTERMITTENT OR CONTINUOUS ALARM
Probable Causes:
A. DC voltage supplied to detector is inadequate, intermittent,
or polarity reversed.
Remedy: Ensure that proper polarity and adequate voltage
is supplied and that wiring is intact (no opens or
shorts) and connections secure.
B. Protective loop is interrupted (open).
Remedy: Determine whether interruption is in protective
loop wiring or at detector's alarm relay contacts.
Disconnect protective loop at detector relay
contact terminals and check continuity across
terminals. If absent at terminals (and proper
voltage is supplied to the detector), return unit for
service. If present, check protective loop wiring.
LED INOPERATIVE
Probable Causes:
A. LED enable/disable plug is installed.
Remedy: Remove LED enable/disable plug.
B. LED malfunction. Check for broken/shorted leads.
Remedy: Return unit for service.
NO ALARM WHEN MOTION TAKES PLACE IN THE
PROTECTED AREA (LED DOES NOT LIGHT)
Probable Causes:
A. Detection area has changed. Possibly due to repositioned
furniture or equipment in the protected area.
Remedy: Caution customer about layout changes.
