SECTION 3D - SET-UP INSTRUCTIONS
2-Door Restroom (Mode 4)
This application is a shared-use (normally unlocked) restroom
between two suites (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, and 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 locks both doors – the strike is
energized, and exterior switches are removed from the circuit.
To exit the restroom, push either interior wall switch. The
respective door unlocks, opens and resets the system. Should
either door be opened manually, the magnetic contact 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.
Utilizing the dry contact output (Relay #5) or the LED output is
strongly encouraged to indicate "Occupied" on the exterior of
both doors to let others know the restroom is in use.
Step 1
Select MODE 4 via the first 3 positions
of the dip switch as shown:
See Diagram 1 for location of dipswitch,
connectors, & potentiometers.
IMPORTANT: Any changes to Mode selector or Out2 settings
must be made with power off!
Step 2 - Dip Switch Options
Leave switch #6 OFF to enable the panic button to unlock the
door only, but not open it. Put dipswitch #6 ON when you
want the panic button to unlock the door and also open it.
Furthermore, if dipswitch #6 is set to ON, and dipswitch #8
is set to OFF, then only the last door used will open. Setting
dipswitch #8 ON, will open both doors simultaneously.
Push dipswitch #7 ON, to enable the 15 minute Time-out
(reset) feature. Leave in OFF position if you do not want an
automatic reset.
Use of Relay 5 is optional, and set according to dipswitches
#4 & 5 (See diagram 1 for location). A common use in this
mode would be that Relay 5 follows the lock relay and lights
an occupied sign. It could also be utilized for the second door
lock, rather than connecting both door locks to Relay #1
output. By default, Relay #5 follows Relay #1.

Step 3 - Connections
Refer to Diagram 5 for the following connections. Wire all
input connections to the (removable) Input terminal strip
(numbered 1-14). Firmly re-insert connector if removed.
Make your connections to the relay output strip (numbered
1–15). Both door locks may be connected to Relay #1 or, wire
one lock to Relay #1 and the other to Relay #5.
Re-insert connector.
The 7-pin Digital I/O strip provides either 12 VDC or 5 VDC on
Terminals 6 & 7 for lighting "Occupied" LED's. This output is
present whenever the door is locked. Select output voltage
using jumper as shown:
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 2–5. Pot #1 has no effect.
Timer 2: Operator Delay-on-Activate
Timer 3: Operator Delay-on-Release
Timer 4: Panic Relay (#4) ON time
Timer 5: Panic Relay (#4) OFF time
Note: If pot 5 is turned to zero, relay will be on steady.
Apply power to door operators (EMF-2) and all connected
equipment (strikes, lights, etc). Observe the red Power LED on
OFF / ON
the unit, which should light. If not, re-confirm proper voltage
1
and/or terminal strip connection.

Press the exterior wall switch at door #1. If restroom is
3
unoccupied the door will open automatically. Pot #2 adjusts
the door hold-open time (up to 30 seconds). If restroom is
occupied and the Lock button has been pressed, the door will
not open (an Occupied light would be lit).
After entering the restroom, push the nearest Lock button.
The EMF-2 will energize both electric locks and remove both
exterior Push switches from the circuit.
To exit the Restroom, two options are available:
1. To have the door unlock and open automatically, push
the respective interior wall switch. This also resets the EMF-2
for the next person to use.
2. The door may also be used manually. To exit the
restroom, turn the (lever) handle and pull (push) the door
open. The magnet switch resets the unit into standby
mode. The Occupied lights / LED's will extinguish.
Repeat the above procedure door #2.
It should function exactly as above.
