CAUTION
RADIO RECONFIGURATION
If present we strongly recommend that the radio
terminal strip be changed so that if a radio is used it
can OPEN and/or RESET the timer rather than
OPEN and CLOSE. This prevents accidental closing
of the door when someone pushes the transmitter at
the wrong time.
1 Trace the yellow wire from the R2 terminal on the
radio strip (if supplied) to terminal #7.
2. Move this yellow wire from terminal #7 to terminal
#1 (see figure 3).
NOTE:
If reconfigured, users of the radio can be told that if
they are not sure when the door will close they can
press the transmitter to reset the timer.
TIMER DEFEAT (optional)
If a timer defeat switch is desired cut either purple
wire and wire in a simple on/off switch.
INSTALL THE CONTROL STATION WHERE THE
DOOR IS VISIBLE, BUT AWAY FROM THE DOOR
AND ITS HARDWARE. IF CONTROL STATION
CANNOT BE INSTALLED WHERE DOOR IS
VISIBLE, OR IF ANY DEVICE OTHER THAN THE
CONTROL IS USED TO ACTIVATE THE DOOR,
REVERSING EDGE MUST BE INSTALLED ON
THE BOTTOM OF THE DOOR.
INSTALL A REVERSING EDGE UNDER THESE
CIRCUMSTANCES MAY RESULT IN SERIOUS
INJURY OR DEATH TO PERSONS TRAPPED
BENEATH THE DOOR.
