PASSIVE INFRARED
MOTION DETECTOR


INSTALLATION
INSTRUCTIONS

GENERAL INFORMATION

This passive infrared motion detector is a versatile recess
-mounted
unit
employing a wide
-angle
Fresnel lens' and offering an efficient
protection patte
rn for commerc
ial 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 co
verage will be obtained if mounting is selected such that the
likely direction of intruder motion is across the pattern.

The Detector features installer
-selectable Alternate Polarity Pulse
Count, which provides protection against false alarms
' Optional long
range and pet alley lenses are available.

ect 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 detector in areas which contain objects likely to
produce a rapid change in temperature, such as central heating,
radiators or ducts
, air conditioners, open flame, etc
.

Do not mount on an unstable surface.

Important:
Avoid running alarm wiring close to heavy
-duty electrical
power c
ables

PROTECTION PATTERNS

The PIR's protection pattern can be modified to suit the needs of a
particular area by selective use of the masking strips supplied. Two
interchangeable optional lenses are available for use with the 995 -
a
long-
range lens (995LR
). and a pet alley lens (995PA).
See
Interchangeable Optional Lenses.


DETECTION AREA -
STANDARD (WIDE
-ANGLE) LENS

ACCESSING
THE PC BOARD
To
enable or disable the Alarm LED
or to change the Pulse Count,
you
will need to access the PC board located in the base of the PIR.

Separate the base from the mounting plate as follows:

Holding the base with one hand, bend the upper left
-hand edge of the
mounting plate downward with the thumb and forefinger of the other

hand to sep
arate the base from the mounting plate
in that area. See

Figure 1. Do the same for the lower left
-hand edge, and then detach
the
base.

The PC board is located in the base (
see Fi
gure
2
).
To re-
attach the base, first insert side of base beneath the "lip" on
the

right
-hand side of the mounting p
late, then press down firmly on the left
-
hand
side of the base to "snap" that side securely into position. Make
sure the
base is properly secured to the mounting plate, but able to slide
up or down
to possible future v
ertical adjustment.





LED ENABLE/
DISABLE

The detector is shipped with the Alarm LED disabled (LED
enable/disable plug in place). The LED should be enabled (for the
walk
-test to follow) by removing
the LED
enable/disable plug (
see
Fig
ure 2 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).


Figure 2. PC Board (in base of PIR)

PULSE COUNT OPTION

Each detecto
r includes Pulse Count circuitry that
is designed to
provide
stability in adverse environments to minimize false alarms. 1
-
event pulse count (instant response) is provided by positioning the
jumper plug across the pulse count pins (
see Fig
ure. 2 for location
)
.
To select 2-
event pulse count, r
emove 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 wil
l 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.

INSTALLING THE
PIR

The wall in which the PIR is to be mounted must be firm and
vibration-
free. The PIR is designed for installation in a standard,

single
-gang 2-
1/2" deep recessed electrical box.

1.
Select a location that will provide the coverage desired from the
lens in
use and
install the electrical box there.

2.
Wiring (from the control, etc.) must be brought into the electrical
box
and spliced to the leads on the connector that has been
supplied
(s
ee
Figure 3
).

3.
Attach the connecto
r to the PIR.

4.
Mount the PIR to the electri
cal box using the two screws
supplied
(
see
Figure 4
)
.
Important:
Do not, under any circumstances, drill holes or make any
openings in the PIR's base which is of a sealed design to prevent the
entry of debris
, insects, etc.

VERTICAL PATTERN ADJUSTMENT

The protection pattern provided by the lens in use can be raised or
lowered
before
the PIR is mounted in the wall by sl
iding the base up
or
down (relative to the mounti
ng plate). Use the calibrated scale
provided on the PIR (
see Figure
5
). The pattern may be raised by as
much as +4 degrees or lowered by as much as -
6 degrees.

To Adjust the Pattern after the PIR is Mounted:

If a vertical pattern adjustment is required
aft
er
the PIR has been
mounted, do the following:

1.
Loosen (but do not remove) the two screws that secure the PIR
to the wall.

2.
Using the blade of a screwdriver, slide the tab in the notch on the
right
-hand side of
the PIR's mounting plate upward (to lower the
pattern) or downward (to raise the pattern)
(
see Figure
4)
.
3.
After the adjustment, secure the PIR in the wall by tightening the
screws previously loosened.

Important:
Always
perform
a walk test after any adjustme
nt.

LENS MASKING:

The masking strips that
are
supplied are designed for application to
one or more
lens segments to produce a protection pattern that suits
the particular requirements of the protected area. Individual masking
strips have been provided for each of the lens segments on the
standard
lens supplied with the PIR
. Simply peel off the appropriate
pressure-
sensitive adhesive st
rip(s) and apply over the desired lens
segment(s).
Be sure to affix the masking strips to the
inside
of the lens
(not the outer, smooth side). Each lens segment that is masked
results in the elimination of one zone of protection from the coverage
pattern. By masking segments of the lens, you can adjust the
coverage to suit the area to be protected or
eliminate coverage from
areas where you anticipate environmental disturbances that might
reduce the PIR's stability (a heater or other heat
-producing object for
example).

INTERCHANGEABLE OPTIONAL LENSES

In addition to the standard lens supplied with the No, 995 PIR, two
optional lenses are available which may be
used to provide long-
range or pet alley protection patterns. Protect
ion patterns for these
optional lenses are provided below. I
f one of the optional lenses is
being installed in place of the standard lens
, refer to
Changing
Lenses
in this document
.

Chan
ging Lenses

1. Separate the base from the mounting plate
(
see
Figure 1
)
.
2. Release the lens securing the
frame in the mounting plate by
applying pressure on each side of the frame
(
see Figure 6
).

Remove the frame temporarily.

3 Remove the existing lens
carefully.

4 Insert the new lens into the area of
the previous lens Make sure
that the smooth side faces outward (away from you), and that the
word TOP and its identifying number are at the top. (
see
Figure 6
)
.
3. Re
-inst
all the f
rame by squeezing on each side and then pushing
down to lock into position.

4. Press the base onto the mounting plate
until
it “snaps
" in
place.

5. After changing lenses, a walk
-test
must
be performed.

TEST PROCEDURES

Important:
A 2
-minute warm
-up time is required after applying power
.
Testing should be
performed
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. The Puls
e Count jumper plug in the PIR must be in the single-
event
(instant response) mode (plug installed). The Alarm LED must be
enabled at this t
ime (LED enable/disable plug removed).

2. Walk through the
protective zones, observing that the PIR's LED
lights whenever m
otion is detected (the LED serves as a Walk
-
Test indicator during this procedure).

Note:

In the single-
event (instant) pulse mode, the LED stays
lit
(and the alarm relay contacts remain open) for

approximately 1 to 3 seconds after detecting motion.

3. If the
pul
se count is to be used in this application, remove the
pulse
count jumper plug from the pulse count pins, and repeat the
walk
test p
rocedure. In the pulse count mode, the LED serves as
an
alarm indicator.

The absolute range of all PIR units is subject
to v
ariation because of
different types of clothing, backgrounds and ambient temperature.
For
this reason, ensure that the most likely i
ntruder routes are well
within the PIR's protective zones and that walk
-testing is carried out
along these routes
.
After
the
initial walk test, we recommend the following to verify
proper aiming of the PIR:

Repeat the walk test
in a semi
-crouching position
(kneeling with top
of head approximately 3 feet from the ground -
4-1/2 feet if using the
Pet
Alley lens), at the rated max
imum range of 40 feet (or at the
maximum
range possible if less than 40 feet) If performance
degrades under these conditions, the pa
ttern must be lowered for
proper aiming. See Vertical Pattern Adjustment"
.
After the "Walk
-Test" is complete, the LED may be
disabled (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 tor
at least 4
hours
of operation during emergencies.

2. Units should never be re-
aimed or relocated without the advice or
assista
nce 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 performed
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 reposition detector if 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 t
o 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 detector terminals (and
proper voltage is s
upplied 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 cust
omer about layout changes. Vertical or
horizontal pattern adjustment of the PIR may be necessary.

CONTROL PANEL INDICATES CONTINUOUS
FAULT IN ZONE OF
PROTECTION CONTAINING PIRs. (PIR'S
ALARM
LED
NOT
LIT)

Probable Cause:

A.
Too many detectors being used in
the zone. Each detector adds
15 ohms of series resistance and the zone's allowable loop
resistance is being exceeded.


Remedy
:

Reduc
e the number of detectors used in the zone
until the series resistance is within the allowable loop resistance
permitted by the control.

COMPLIANCE NOTES:

Product should be tested at least once each year
.
