CX-EMF-2 MULTI-FUNCTION TIMER

Emergency Panic Switch (optional)
Should an emergency occur, and assistance from the outside
is required, the occupant can push a button or ribbon switch to
signal the EMF-2 (input #3). When activated, the EMF-2
will unlock the door (and optionally open the door). A
maintaining type input is required to keep the door held open.
Based on the settings of Dipswitch #6 & 8 either the doors will
unlock only, or the last door used will open or, both doors will
unlock and open simultaneously.
Relay #4 is now activated, which can be used to signal for
assistance, sound an alarm – whatever you choose. The
installer can choose a continuous or pulsing output, depending
on the settings of potentiometers #4 & 5.
Emergency Time-out Feature
An added safety feature in the EMF-2 is the ability to
automatically reset to standby mode after a fixed lock time of
15 minutes. The door unlocks, so that personnel may enter
the restroom. This feature is engaged by turning dipswitch #7
to ON position. If not desired, simply leave dipswitch 7 OFF.
SECTION 3E - SET-UP INSTRUCTIONS
2/3 Door Airlock (Mode 5)
This is designed to control up to 3 sets of sliding, or swinging
doors. The relay allows 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.
For 2-door airlocks, the installer can set up "Auto-crossing"
whereby after triggering one door, the second door activates
after the first door closes (also known as bi-directional
door 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.
Step 1
Select MODE 5 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
Use of Relay 5 is optional, and set according to dipswitches
#4 & 5. Push switch #6 ON for "Auto Mode" (door sequencing).
In this Mode when input A is activated, first door A opens,
then when closed again, door B opens in sequence.

Conversely, when input B is activated, first door B opens, then
when it is closed again, door A opens sequentially. A third
door cannot be used in "Auto-Mode". Selecting this mode
disables door C input and contact input.
Set dipswitch #7 ON for airlocks containing 2 doors only, or set
to OFF for 3 doors. Dipswitch #8 has no effect in this mode.
IMPORTANT: Any changes to Mode selector or Out2 settings
must be made with power off!
Step 3 - Connections
Refer to Diagram 6 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 open when the door opens. Any other
configuration will cause the relay to malfunction. We suggest
standard door contacts (ie.Camden Model #CX-MDC).
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 1–3 & 5.
Pot 4 is not used in this mode.
Timer 1: Door A Delay-on-Release
Timer 2: Door B Delay-on-Release
Timer 3: Door C Delay-on-Release
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.
OFF / ON
If a request to open comes in from another door while the
1
first is still open, it will retain the call in memory until the
2
Door Sense switch indicates the first has closed. If there is
3
a succeeding request on the first door (or the door that is
already opened), it will keep that door opened.
If automatic sequential operation between doors A and B is
desired, put dipswitch #6 into ON position. Otherwise, for
normal operation, leave this dipswitch off.
Potentiometer #5 is useful if the application utilizes locks only,
and not automatic door operators.
