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.
