CX-EMF-2 MULTI-FUNCTION RELAY
APPLICATION 5 - TWO TO FIVE DOOR AIRLOCK/INTERLOCK
This function is designed to control up to
5 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.
The outputs may be wired to electric locks,
or to automatic door operators. The inputs
could be simple door switches or a secure
means such as keypads, Prox readers, etc.
For 2-door airlocks, the installer can set up
”Autocrossing” whereby after triggering
one door, the second door will activate
after the first door closes. (This is also
known as bi-directional door sequencing).
Should a door become stuck open or closed, a Trouble signal is
output after a predetermined time. The EMF-2 also includes a
”Lock-down” input that resets the system and/or disables all
”Open” requests.
APPLICATION 6 - TWO DOOR MANTRAP
This function is designed to control a 2-door
mantrap with or without automatic door
operators. 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. (The memory feature
may be disabled)
An input is available for a contact
mat on the floor to ensure that only
one person is within the mantrap at
any time.
Should a door become stuck open or
closed, a Trouble signal is output after
a predetermined time.
Finally, a ”Lock-down” input is available
which immediately locks all doors and
disables further egress/ingress.
