SETTINGS & ADJUSTMENTS
potentiometer
Potentiometer: Detection Zone*
countclockwise = decrease (4'' minimum)

TIMED MODE – Recommended for automatic door applications. In Timed Mode, a detection activates the
relay and the relay holds for a predetermined amount of time (0.5 seconds, not adjustable).
TOGGLE MODE – Recommended for switch applications. In Toggle Mode, a detection activates the relay and a
second detection deactivates the relay. The relay will hold indefinitely until a second detection occurs.
For the 900 MHz wireless programming instructions, please reference BEA User's Guide 75.5937 which
comes with the 900 MHz wireless receiver (sold separately).
