OPERATION

Prewired terminal strip accepts field connection of any access control device with normally open (N.O.) output contact (most access control equipment) and when required, a separate OPEN/CLOSE pushbutton (supplied).

Plug-in connectors are included for addition of a loop detector to open and/or a loop detector to hold open (not supplied). Activation of access device open button, or loop detector to open will raise gate. Gate will lower automatically unless hold open loop detector is activated or unless CLOSE button wiring has been made, in which case gate will remain open until CLOSE button is pushed.

An optional timer will extend the time that the gate remains open. AUTO/MANUAL switch holds arm in vertical position.
