ADJUSTING AND OPERATING THE SLI® 259A
The SLI 259A microwave sensor has two DIP switches. The switches are used to
program and operate the sensor. The four functions of the switches are:
MODE
EXTERIOR
ADJUSTMENT
INTERIOR
ADJUSTMENT
ARM MODE
ARM W/PER.

EXTERIOR ZONE ADJUSTMENT (Alarm must be armed to adjust SLI 259A)
This mode lets you adjust the sensitivity of the exterior detection zone. The SLI 259A
will not trigger the alarm in this mode, but the LED will flash green when motion is
detected. To increase sensitivity, turn the exterior adjustment knob clockwise. The
maximum exterior sensitivity will vary based on installation and the type of vehicle.
INTERIOR ZONE ADJUSTMENT (Alarm must be armed to adjust SLI 259A)
This mode lets you adjust the sensitivity of the interior detection zone. The SLI 259A
will not trigger the alarm in this mode, but the LED will flash red when motion is
detected. To increase sensitivity, turn the interior adjustment knob clockwise.
IMPORTANT– An operational problem may occur with the sensor if the interior
sensitivity is greater than the exterior sensitivity (i.e. false alarms). In this case, the LED
will flash yellow when the switches are put into the arming mode.
ARM MODE
When the alarm is armed, the SLI 259A
will power-up for 15 seconds. During this
period, the LED will be solid green. After
15 seconds, the SLI 259A will operate
normally. When the exterior zone is
penetrated the sensor will trigger the
alarm's pre-intrusion input. This also
activates the interior zone. When the
interior zone is penetrated, the LED will
flash red and the alarm will be triggered.
ARM MODE WITH PERIMETER ALARM
In this mode the SLI 259A will operate
exactly as in "ARM MODE", except that if
the perimeter zone is penetrated 4 times within 15 seconds, the SLI 259A will trigger
the alarm. After the perimeter is penetrated a second time, the alarm's pre-intrusion
input may be triggered twice (varies from alarm to alarm), warning you that the alarm
will trigger if the perimeter field is penetrated a fourth time.

THE SLI® 259A MICROWAVE SENSOR
The SLI 259A detects the movement of mass through a protected area (i.e.
an arm reaching into a car or a door being opened). The SLI 259A
has
dual-zone protection. It combines both perimeter pre-intrusion warning and
instant interior trigger protection. It does this by transmitting and receiving a
high-frequency RF signal. When an object moving towards the vehicle is
detected, the high-frequency RF signal will change. This change will cause
the microwave sensor to send a trigger signal to the alarm.
While the SLI 259A
detects movement of mass, it will not false alarm due to
wind, rain, air movement, flying insects, or vibrations. It is perfect for
protecting the interiors of convertibles, Jeeps, or other "open air" vehicles.
The SLI 259A, when positioned correctly, will protect the entire vehicle.
Because of the SLI 259A's revolutionary design, the unit's RF signal will pass
through carpet, glass, plastic, or cloth, but not through metal.
INSTALLATION CONSIDERATIONS
1. The shape of the protection field is symmetrical and elliptical. The
sensor
must be centered between the left and right side of the vehicle.

2. The sensor should be mounted as low as possible since the protection
pattern extends out in front and above the sensor.
3. Do not mount the sensor behind metal objects, since microwaves will not
penetrate metal.
4. Do not mount the sensor on metal as it will affect the sensor's tuning.
5. The optimum mounting location is in the center of the vehicle at the base
of the rear seat or in the rear seat itself. If a rear location is not
accessible, then mount the sensor in the dashboard or center console,
but watch for metal objects
like the stereo or brackets.
