2-Door Controller
INSTALLATION MANUAL
Controlled Entry with Free Exit
Entry through two doors can be controlled with one controller by installing a reader/keypad on one side of
each door. If the door status is monitored by a door contact (reed switch) then a “request to exit” (REX) device
such as a motion detector, push button or oor mat sensor must be used so that the system can dierentiate
between a door forced open and an authorized exit. The REX can be programmed for free exit according to a
specic schedule, otherwise a “door forced open” event will be generated.
