Generally, if distances are kept below 100 feet, there should be little problem with the setup.
Factors that degrade the RF performance will be thick vegetation, buildings, or metal objects. For
longer range applications, repeaters are available that will send the alarm signal up to several
miles if so desired.
Range Test can be repeated if desired by pressing and holding the sensor
PROGRAMMING
BUTTON
until the
BLUE LED
comes on. After the
BLUE
LED
comes on, immediately release
the
PROGRAMMING BUTTON
. Wait for several seconds and trip the Sensor with your hand.
When the Sensor trips, it will start transmitting at one second intervals with the Sensor
BLUE
LED
flashing. Range Test will normally last for about 1 to 2 minutes. Range Test can be aborted
at any time by momentarily pushing the
PROGRAMMING BUTTON.
The Sensor will then go into
the active Alarm Mode.
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 different 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 and the sensor’s
BLUE LED
will flash and an alarm
will be transmitted to the
System II’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, it 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 II 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.
