Set-up Instructions
2 / 3 door Airlock (Mode 5)
This function is designed to control up to 3 sets of
sliding, or swinging doors. The relay will allow only 1
door to be open at a time.
It accomplishes this by a Door Sense input, such as
a magnetic contact switch, located at each door. If
the Door Sense determines that a door is open, then
it will not allow a second door to open, but
remembers the request to open and allows it once
the first door has closed.
For 2-door airlocks, the installer can set up "Auto-
crossing" whereby after triggering one door, the
second door will activate after the first door closes.
(This

sequencing).
Should a door become stuck open, a Trouble signal
is output after 5 minutes. The EMF-2 also includes a
"Lock-down" input that resets the system and/or
disables all "Open" requests.
