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.
