Operating Controls
All operating controls are on the front panel of the 1461, as
shown in Figure 3.
Power ON LED This LED is lit when power is applied to the
unit.
ALERT These two flash alternately when
motion has been detected, until turned off by AUTO RESET or
by a manual RST (Reset).
RST (Reset) Button After an alert has been indicated this
button restores the unit to the motion detection mode and stops
all alert signals. If the motion is still detected, the unit returns
immediately to the alert condition. The manual RST function
is available regardless of the AUTO RESET switch setting.
SENS (Sensitivity) This screwdriver control adjusts the
sensitivity of the active detection area. Clockwise rotation
increases sensitivity.
VERT (Vertical) P and S These recessed screwdriver
controls adjust the vertical position and size of the rectangular
detection area. The P control adjusts the vertical position and
the S adjusts the vertical size of the area.
DISPLAY This two position toggle switch activates (+)
or deactivates display of the two vertical bars indicating the
area of the picture in which motion is detected. (See Figure 4,
On-Screen Display, page 4.) It does not otherwise affect the
operation of the unit. The activated (+) position is normally
used unless public display of the area in which motion is being
detected is inadvisable.
BYPASS This toggle switch activates (+) or deactivates
the audio alert, the switcher call-up logic output and the
auxiliary start relay functions of the motion detector. It must
be in the activated position when these functions are
desired. The visual ALERT LED’s are not affected by the
position of the BYPASS switch. In the deactivated
position, when an alert occurs the LED’s flash, but the audio
signal, the switcher logic, and the relay are not active.
AUTO RESET This toggle switch activates (+) or
deactivates the automatic reset of the motion detector.
When activated an alert condition automatically is cleared
12 seconds after motion ceases. When deactivated the
manual RST must be used to clear an alert condition.
HORIZ (Horizontal) P and These recessed screwdriver
controls adjust the horizontal position and size of the
rectangular detection area. The P control adjusts the horizontal
position and the S adjusts the horizontal size of the area.
