CX-EMF-2 MULTI-FUNCTION TIMER
I NSTA LLAT I O N I N S T RU C T I O N S
Should a person approach a door and request the door to
unlock, then change his/her mind and "walk-away", pot #5 can
be set to ignore that request after an adjustable time. This
time would be set at or close to minimum. For automatic door
applications, it could be set higher (10–15 seconds.)
Switch closure on Input #7 will cause all doors to lock
immediately, regardless of pending "open" requests. Once the
desired operation is achieved, proceed to Section 4, System
Inspection Instructions.
SECTION 3F - SET-UP INSTRUCTIONS
2-5 Door Airlock (Mode 6)
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, it will not allow
a second door to open, but remembers the request to open
and allows it once the first door has closed.
Should a door become stuck open, a Trouble signal is output
after 5 minutes, and may be reset with Input #7.
Step 1
Select MODE 6 via the first 3 positions
of the dip switch as shown:
See Diagram 1 for location of dipswitch,
connectors, & potentiometers.
Step 2 - Dip Switch Options
There are no dip switch options with this mode.
Since all door contacts are wired in series and connected to
Input #6, the unit does not care if less than 5 doors are used.
IMPORTANT: Any changes to Mode selector or Out2 settings
must be made with power off!
Step 3 - Connections
Refer to Diagram 7 (page 14) for the following connections.
Wire all input connections to the (removable) Input terminal
strip (numbered 1-14). Firmly re-insert connector if removed.
NOTE: Magnetic contact switches: This system wants to
see a Normally Closed connection when the door is closed.
The contact will then open when the door opens. Any other
configuration will cause the relay to malfunction. We suggest
standard door contacts (ie. Camden Model #CX-MDC). Wire all
contacts in series as shown in the diagram.
Make your connections to the relay output strip (numbered
1–15). The 7-pin Digital I/O strip provides a trouble output on
pins 6 & 7 after 5 minutes of door ajar.
Connect 12 or 24V AC/DC supply to terminals 1 & 2 of the
2-pin Power Connector (Terminals are not polarity sensitive).

Step 4 - Adjustments
In this application, you will use pots 1 & 5.
Pot 2 - 4 are not used in this mode.
Timer 1: All Doors Delay-on-Release
Timer 2: Not used
Timer 3: Not used
Timer 4: Not used
Timer 5: Timer for clearing "walk-aways"
Apply power to door operators (EMF-2) and all connected
equipment (strikes, lights, etc). Observe the red Power LED on
the unit, which should light. If not, re-confirm proper voltage
and/or terminal strip connection.
Activate an input device to one of the doors. Observe the
respective output LED, which should light immediately. The
door should unlock and/or open.
If a request to open comes in from another door while the
first is still open, it will retain the call in memory until the
Door Sense switch indicates the first has closed. If there is
a succeeding request on the first door (or the door that is
already opened) it will keep that door opened.
Potentiometer #5 is useful if the application utilizes locks only,
and not automatic door operators. Should a person approach
OFF / ON
a door and request the door to unlock, but then change his/her
1
mind and "walk-away", pot #5 can be set to ignore that request
2
after an adjustable time. Typically this time would be set at or
3
close to minimum. For automatic door applications it could be
set higher (10–15 seconds).
Once the desired operation is achieved, proceed to Section 4,
System Inspection Instructions.
SECTION 3G - SET-UP INSTRUCTIONS
2 Door Mantrap (Mode 7)
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, 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, a Trouble signal is output
after 5 minutes. A "Lock-down" input is available which
immediately locks all doors and disables further egress/ingress.
