RANGE TEST MODE:
Range Test Mode is used to verify the maximum RF transmission distance
from the Intellicam Sensor, such as the IR-904 Passive Infrared Sensor, to
the RX-440 Receiver. The Sensor Range Test may be monitored by several
methods. One method is to use the RX-440 itself, the unit can either be
carried while range testing or can be placed near the target area on the
ground, in which case the operator can observe the
RED LED
on the RX-440
Receiver. There is nothing the operator has to do to the RX-440 Receiver
except apply power from the battery pack.
Screw the TC-1 Sensor Tree Clip into the tree, about 3 to 4 feet above the
ground level and install the sensor. It is best to locate the RX-440 Receiver
on the same side of the tree as the Sensor so that the tree will not block the
RF signal. The best range is achieved with line-of-sight conditions, that is,
with no obstructions coming between the Sensor and RX-440 Receiver.
Position the IR-904 Sensor in the tree mount with the antenna vertical. Aim
the Sensor at the target area. To activate the IR-904, remove the plastic
insulator from the batteries. As soon as power is applied, the
sensor’s
RED
LED
should illuminate once, then flash 3 times for Sensor ID 3 then turn off,
and then flash 5 times for Sensitivity 5. After about a 30 second
stabilization period, the Sensor will automatically go into the Range Test
mode that will last for approximately 2 minutes. After two minutes, the IR-
904 will automatically go into Alarm Mode.
When the IR-904 goes into Range Test mode, it will start transmitting with
the Sensor
RED LED
flashing at 1 second intervals. Walk away from the
Sensor with the RX-440 Receiver in your hand. The maximum range will be
found when the
RED LED
on the Receiver stops flashing or becomes erratic.
You should cut this distance in half for a more reliable setup, since
RF/UHF frequencies cannot be predicted with any great certainty
due to absorption and reflections from nearby objects.
The Range
Test should involve your hanging the RX-440 Receiver in a suitable bush or
concealment, with appropriate camouflage. If the
RED LED
flashes on the
RX-440 Receiver become erratic, then you know that you are exceeding the
maximum RF transmission distance. Generally, if distances are kept below
300 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 removing, then reinstalling the
batteries on the IR-904 sensor. As stated above, the sensor will flash ID,
then Sensitivity, then automatically go into Range Test mode. Range Test
can be aborted at any time by momentarily pushing the
PROGRAMMING
BUTTON.
The Sensor will then go into the active
Alarm Mode
.
