CX-EMF-2 MULTI-FUNCTION RELAY

APPLICATION 1 – ABM VESTIBULE INTERFACE RELAY

This application is designed to interface an
automatic door operator with a card reader
system such as those used on banks. When
the unit is switched into ”Night Mode” the
electric strike is energized (door is locked)
and the exterior switch is removed from the
circuit. When a valid card is inserted, the
strike unlocks immediately, and the exterior
switch is put back into the circuit for an
adjustable period, so that if pushed by the
user, it will open the door automatically.
The inside switch can unlock and open the
door at all times. Both the strike and
operator hold times are user adjustable.

A new feature added to the EMF-2 is the
”Lock-Down” switch input. When activated
by a user the relay will ignore the card
reader input and energize a relay contact.

In ”Day Mode”, the electric strike is unlocked
and either switch will open the door. The
card reader is electronically removed from
the circuit.

APPLICATION 2 - SINGLE DOOR UNSECURED RESTROOM INTERFACE

The restroom door control interface is
designed to safely control an automatic door
operator and lock, on a shared use restroom
door in facilities such as nursing homes, hospitals,
shopping malls, etc.

Opening the restroom door via the operator
is accomplished by pushing the exterior wall
switch. The door is then locked by depressing
the ”Push to Lock” button inside – the strike is
energized, and the exterior switch is removed
from the circuit. To exit the restroom, simply
push the interior wall switch. The door unlocks,
opens and resets the system. Should the door
be opened manually, the magnet switch will
reset the system.

Another feature, unique to the EMF-2, is the
emergency input, which allows a panic switch
to unlock, open the door (optional), and send
an emergency signal for assistance.The output can be
maintained or pulsed. The pulse times, strike and operator
delay times are all user adjustable. As an added safety
feature, the relay can be set to automatically reset and
unlock after 15 minutes time.

APPLICATION 3 - SINGLE DOOR, NORMALLY SECURED RESTROOM DOOR

This application is a shared-use single (normally
locked) restroom door in facilities such as doctors
offices, hospitals, shopping malls, etc. The relay
provides control of the lock, operator, and switches,
to provide the utmost in facility security, safety for
the occupants, yet still be easy to install and program.

In this application the door is normally locked

whether occupied or not. It may be unlocked by key­switch, keypad, or another credential. The EMF-2
can be configured to activate the door operator
immediately, or after pressing the wall-switch within
the (adjustable) time period. Once the door has
closed, pressing the ”Push to Lock” button removes
the exterior keypad / key-switch from the circuit. The
electric lock will pulse twice to let the user know
that the door is secure, and an output is available to
light an Occupied LED (s).

To exit the restroom, simply push the interior wall
switch. The door unlocks, opens and resets the
system. Should the door be opened manually, the

APPLICATION 4 – 2 DOOR SHARED-USE RESTROOM

This application is a shared-use (normally unlocked)
restroom between two suites (and therefore utilizing
two doors), in facilities such as nursing homes &
hospitals, etc. The relay provides control of both
locks, operators, and all switches, to provide the
utmost in flexibility, safety for the occupants, yet still
be easy to install and program.

Either door is opened automatically by pressing the
respective exterior wall switch. Once the door has
closed, pressing either ”Push to Lock” button inside
then locks both doors – the strike is energized, and
exterior switches are removed from the circuit. To
exit the restroom, simply push either interior wall
switch. The respective door unlocks, opens and resets
the system. Should either door be opened manually,
the magnet switch will reset the system.

Unique to the EMF-2 is the emergency input, which
allows a panic button to unlock, open (one or both)
door(s), (optional), and send an emergency signal for
assistance. The output can be maintained or pulsed.
As an added safety feature, the EMF-2 can be set to
automatically reset (and unlock) after 15 minutes time.

It is strongly encouraged to utilize the dry contact
output (Relay #5) or the LED output to indicate
”Occupied” on the exterior of both doors to let
others know the restroom is in use.

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.
