SENSOR WALK TEST MODE:
Sensor Walk Test Mode is used to verify the maximum detection distance that the IR-903
Sensor will detect either a human or vehicular target.
First, initiate the Range Test Mode. When the Sensor trips (indicated by flashing
BLUE
LED
), abort the Range Test Mode by quickly “pushing” the
PROGRAMMING BUTTON
.
The
BLUE LED
will stop flashing. The Sensor is now armed and in its Default Mode with a
Sensor ID 3 and the Sensitivity in Full Auto Chameleon and ready for the Walk Test.
(Alternately, you can program a different Sensor ID and a fixed Sensitivity prior to Walk
Test. See Sensor Programming).
With the Sensor aimed at the target area, walk back and forth in the area where the sensor
is aimed. This motion will trigger the Sensor a
nd the sensor’s
BLUE LED
will flash and an
alarm will be transmitted to the System III-
C’s Receiver/Processor.
The Receiver’s
RED LED
will flash when it receives the sensor’s alarm. (The
BLUE
LED
from the Sensor and
RED LED
Receiver/Processor will illuminate only for the first 10
minutes. After 10 minutes, they will no longer illuminate for covert reasons. To reactivate
the
BLUE
LED
on the sensor, simply remove and reinstall the CR-1225 batteries. To
reactivate the
RED LED
on the System III-C receiver,
press the Receiver’s
PROGRAMMING BUTTON
.)
The Sensor takes 4-6 seconds to reset after an alarm is transmitted, so pause briefly
before attempting to re-
enter the Sensor’s field-of-view. After you have located the
Sensor’s beams with the Walk Test method, walk at a slower pace to ensure that detection
will be reliable.
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.
IMPORTANT:
When using the IR-903 Sensor with the
FBA-1 Flashback Adapter
, it is
mandatory that you program the sensor for either
ID 1
or
ID 2
as those are the only
ID’s
that are compatible for use with the
FBA-1 Flashback Adapter.
*This applies to any and all sensors used with the FBA-1.
