Person walking across detection path
ITI Part No. 60-XXX
Document Number: 466-xxxx Rev. A PRELIMINARY
April 2000
P roduct Summar y
A motion sensor (passive-infrared or PIR) detects movement within a specific area by sensing the infrared energy
emitted from a body as it moves across the sensor’s field of
view, causing a temperature change in the sensor’s zones.
When this motion is detected, the sensor transmits an alarm
signal to the control panel.
Use this motion sensor to protect locations where door/window sensors are impractical or not needed. For example,
use a motion sensor to protect large areas or open floor
plans. Motion sensors also provide backup protection for
door/window sensors.
The ITI
custom designed lens, and a new custom designed sensing
element. The combination of these improvements provides
false alarm immunity for pets with a combined weight of up
to 40 pounds while still providing superior human catch
performance.
This wireless motion sensor includes the following features:
❑ 35 feet by 40 feet coverage area
❑ Three minute transmitter lockout time after an alarm
❑ Cover-activated tamper (optional wall-activated tamper
❑ Supervisory signal transmitted every 64 minutes to the
❑ Sensor low battery reports (trouble) to the control panel

Installation Instructions
3. Position the sensor to protect an area where an intruder
would be most likely to walk across the detection pattern (see Figure 1).
4. Mount the motion sensor o n an insulated, outside wall facing in.
5. Mount the motion sensor on a rigid surface which is free from vibrations.
6. Position the sensor so it faces a solid reference point, like a wall.
7. Do not aim the sensor at windows, fireplaces, air conditioners, area heaters, forced air heating vents, or place
it in direct sunlight.
8. Do not mount the sensor near duct work or other large
metallic surfaces which may affect the RF signals.
Actual acceptable transmitter range should be verified
for each installation.
9. Mount the sensor permanently on a flat wall or in a corner. Do not set it on a shelf.
10. Windows should be closed in any area which has an armed motion sensor.
11. The pet must not be allowed to climb on objects such as
furniture, boxes, etc. within the field of coverage. See
Figures 2 and 3 to determine the sensor’s field of coverage.
12. Room temperature must be kept at 60º F or higher.
13. The sensitivity switch must be set to Standard.
I nsta llation Guide lines
This PIR was designed for use in the presence of pets having a combined weight of up to 40 pounds. The following
installation guidelines must b e met to provide this false
alarm immunity.
1. If possible, locate sensors within 100 feet of the panel.
While a transmitter may have a range of 500 feet or
more out in the open, the environment at the installation site can have a significant effect on transmitter
range. Sometimes a change in sensor location can help
overcome adverse wireless conditions.
2. The required mounting height is 7 1/2 feet.

6. When testing is completed the PIR can be securely
attached to its mounting plate by screwing the smallest
enclosed screw into the hole at the top of the mounting
plate.

For pet applications, the PIR must be set to standard sensitivity.
Walk Testing t he M o tion Sensor
Walk testing should be done to determine the sensor’s
actual coverage area. The edge of the coverage pattern is
determined by the first flash of the LED. This may change
slightly depending upon the sensitivity setting. Walk test
the unit from both directions to determine the pattern
boundaries.
1. Remove the sensor body from the mounted mounting
plate, activate the tamper switch, and then remount the
body to activate the 60 second walk test mode.
2. Walk across the coverage pattern to determine the coverage area, indicated by LED activation. Each activation extends the walk test mode for an additional 60
seconds.
After 60 seconds without motion the walk test mode and the
LED will no longer activate when motion is detected.
CAUTION
Excessive use of the walk test mode may reduce
battery life. Use only for ini tial setup an d maint enance
testing.
Note
This sensor must be incline-mounted on a wall surface or
incline mounted in a corner at a mounting height of 7.5 feet.
When the walk test mode has ende d, an alarm can be
transmitted only after 3 minutes have passed since
the previous alarm. This 3 minute lockout time
reduces unnecessary RF transmissions in high traffic
To mount the se nsor:
1. Remove the mounting plate by depressing the button
on the top of the sensor body. With the opposite hand
pull the mounting plate away from the body of the sensor.
2. Punch out two of the bottom four mounting holes. Use
the lower-side holes for corner mounting, or the lowermiddle holes for surface mounting.
areas thereby extending battery life.
Environment Testing
Turn on all heatin g or air conditio ning sour ces which would
normally be active during the protection period. Stand
away from the sensor and outside the coverage pattern and
watch for alarms.
3. If you desire wall-tamper functionality, remove the wall-tamper knockout.
Note
The wall-tamper switch cannot be used when the sensor is corner mounted.
4. Mark the location of the required h oles on the mounting surface.
Programming
Refer to the panel installation manual for information on
programming the sensor into the panel.
To trip the sensor:
1. Remove the back cover to activate the tamper switch.
