Power Connections
The control board provides a 24v DC output to power external devices and controls.
Alternatively, for devices that require a power supply other than 24v DC, the
operators Power Box contains a convenient 120v AC receptacle to connect a plug-in
transformer.
! TECHNICAL TIP:
Each input Terminal (i.e. Radio, Exit, Re-Open, UL) has a corresponding
Status LED that when illuminated indicates an input is currently being provided to the
terminal and the gate is responding accordingly. (See pages 36-37 LED References)
