Battery Compartment:
The IR-301’s batteries are self-contained. Slide the rubber boot off the back
of the sensor and replace the batteries with 2 each CR1225 Lithium
Batteries. These should power the IR-301 for approximately 2-3 weeks
depending on the number of sensor activations. When not using the sensor,
you can disconnect the power by slipping a small piece of plastic between
the + lead and the top battery.
Red LED:
The
RED LED
is an alarm indicator. It only illuminates when an alarm
occurs during the first 10 minutes to aid in the initial set up and will
automatically turn off after 10 minutes for covert reasons.
Antenna:
The flexible stainless
ANTENNA
allows for the UHF propagation of the RF
signal. The
ANTENNA
must be oriented in a vertical direction for best RF
propagation and for proper alignment of the infrared beams.
Lens:
The IR-301’s focal length is preset to detect a person at an optimum
distance of 20 feet, although it will work satisfactorily over a range of 5 to
30 feet. Its field of view is about 6 feet wide at a distance of 30 feet. The
LENS
is aimed in the direction of your target area.
