The RL-2 is a relay lockout device designed for use with a presence sensor (DH97) on automatic swing or fold doors. Since the door is normally detected when closing, the RL-2 locks out the presence sensor during the closing cycle. To provide safety during this lock out time, a safety beam (GD11S) is required at the end of the safety zone for one way traffic. Interrupting the safety beam will reset the RL-2 bringing the overhead safety sensor back into the safety circuit thus inhibiting the door from reopening. Consult ANSI A156.10.
