SENSOR PROGRAMMING:
IR-903 Passive Infrared Sensors:
The IR-903 Passive Infrared Sensors can be programmed with a different Sensor ID and
Sensitivity Levels, or it can be used in the Default Mode, where the Sensor ID 3 and the
Sensitivity is set to Full Auto Chameleon. Programming Sensor ID’s is helpful when deploying
multiple sensors in the same area. The Default Mode is the simplest to use, requires no
programming input, and comes up automatically after power is applied and the Range Test is
completed. The Default Full Auto Chameleon Sensitivity is highly recommended for most
applications, particularly when the ambient temperature changes considerably during the day, in
which case the IR-903 will automatically adjust the sensitivity for the best Signal (target) to Noise
(background) ratio.
If programming is desired, enter the Sensor ID followed by the Sensitivity. The Sensor ID tells
the Receiver/Processor which Sensor went into alarm. The Sensitivity determines how far away
the Sensor will detect a target
.
Optional Sensor Programming:
When power is applied the IR-903 enters the programming menu, the
BLUE LED
will illuminate
for 5 seconds. The user may press the
PROGRAMMING BUTTON
to program a Sensor ID and
Max Sensitivity. Each button press will reset the menu timeout to 3 seconds. After each
programming menu, the IR-903 will play back the entered Sensor ID and Max Sensitivity. If the
user does not program a Sensor ID or Max Sensitivity, the IR-903 will play back the default
Sensor ID of 3, or the default Max Sensitivity of 5.
Sensor ID Menu:
The first menu is the Sensor ID menu. When power is first applied the IR-903 enters the Sensor
ID menu, the
BLUE LED
will illuminate for 5 seconds. The user can program a Sensor ID from 1
to 5 by pressing the
PROGRAMMING BUTTON
1 to 5 times. After the Sensor ID menu times
out, the IR-903 will play back the Sensor ID. If the user does not program a Sensor ID, the IR-
903 will play back the default Sensor ID of 3. The Sensor ID is transmitted when the IR-903
detects a target. The Sensor ID is used by
some
receivers to perform different functions.
Max Sensitivity Menu:
The second menu is the Max Sensitivity menu. After the confirmation of the Sensor ID, the
BLUE
LED
will illuminate for 5 seconds, at which time the user can program a Max Sensitivity from 1 to
5 by pressing the
PROGRAMMING BUTTON
1 to 5 times. After the Max Sensitivity menu times
out, the IR-903 will play back the Max Sensitivity. If the user does not program a Max Sensitivity,
the IR-903 will play back the default Max Sensitivity of 5. The Max Sensitivity determines how far
away the IR-903 can detect a target. Setting a Max Sensitivity less than 5 may be necessary if
there is environmental noise in the IR-903 field of view, and the user wished to detect targets
closer
than the environmental noise. Regardless of the Max Sensitivity, the IR-903 will still use
Chameleon
™ Environmental Adaptive Technology
to lower the sensitivity if the environment
becomes unstable. When the environment is stable again, the IR-903 will raise the sensitivity
back up to the Max Sensitivity. (See Page 14 for more information on Detection Distances.)
