Electrified Locks, Relays and Timers
CX-EMF-2 / EMF-2m
Multi-Function Timer
INSTALLATION INSTRUCTIONS
1. GENERAL DESCRIPTION
Camden's EMF-2 (EMF-2m or EMF-2ABM) is a microprocessor controlled multi-function relay. This all-in-one design replaces our
previous models EMF-1, EMF-1m or EMF-1ABM. The EMF-2 is designed for specialized applications such as ABM vestibules, one or two-
door restrooms in shared-use facilities, 2 – 5 door airlocks, and secure man-traps.
Dip switches let you choose the mode, and the unit automatically programs the inputs, outputs and potentiometers accordingly.
Removable terminal strips simplify wiring chores, and all adjustments are conveniently located on one end of the case.
IMPORTANT:
Do not apply power to the unit until you have read the instructions fully and made the required adjustments.

In addition to the above, Model EMF-2 ABM includes a lockable
metal cabinet to house the relay. The cabinet is equipped with two
lighted push-switches - on to turn the relay power on or off, and the
other to control the DAY/NITE function.
Mounting
The EMF-2 should be mounted in a clean dry location out of direct
contact with the elements. Suitable locations include inside a
metal box, operator header, or above a false ceiling.
If placed on top of a header, ensure that unauthorized personnel
cannot tamper with the unit.
If used in an Airlock or Mantrap application, the relay may be
located at either door location, or, centrally to all doors.
You must bring wiring from all door actuators to this unit
(as well as the lock, operator, and door contact outputs
as appropriate).
The EMF-2 is also available in an attractive lockable metal cabinet
version (EMF-2m or EMF-2ABM), suitable for wall mounting.
Wiring
Wiring of this unit is dependant on the mode desired. Select
your intended application, then proceed to the section indicated.
Note:
Do not wire Safety devices to the EMF-2. If installed, wire
your safety device directly to the operator control box.
IMPORTANT: Changes to the Mode and Out2 do not take
effect until a power reset. It is therefore best to make these
adjustments with the power turned off!
NOTE:
We highly recommend the use of a regulated power
supply when powering equipment for barrier-free washroom
applications where the strike power may be maintained from
a few minutes to many hours. We offer a low-cost board-only
regulated power supply - CX-PS13 V2, which in turn can be
powered from a small 24VAC transformer, (or the auxiliary power
on the door control) and will supply clean, filtered & regulated
24 VDC power for the strike and EMF-2.
