Applications
The room switch turns on and off both regular
and emergency luminaires simultaneously.
This is accomplished by having the room switch
leg power activate the
Emergency Power Control, EPC-1-M.
In the past all emergency lights had to be on 24
hours a day to meet safety codes. However,
now you can specify and install a UL 924 listed
emergency power control device that can
convert and control up to 20 regular light fixtures
to approved emergency lights, which can then
be turned on and off in the same manner as your
regular lights. The emergency power control
Model EPC is ceiling mounted in a single gang
plaster ring and is usually located in the room or
area where the emergency fixtures are.
Patented Automatic Diagnostic Feature
The unique feature of the EPC-1-M is the ability
to place the unit in any location because the
unit does not require an accessible test switch.
Instead, when the room switch is turned off, the
emergency luminaires stay on for 2.5 seconds
and indicate that an emergency power source
was available and that the EPC-1-M, ballast, and
lamp(s) are all functioning correctly.
This feature eliminates the need for manual
monthly testing and is approved for this purpose.

Emergency Power Source
and Method of Operation
The emergency luminaire power is derived from a 24
hour central emergency power source. The local
utility power company normally supplies the power
through a UL1008 Transfer Switch or equal, but
during a utility power failure, the transfer switch auto-
matically switches to the emergency power source.
The room switch turns on and off both regular and
emergency luminaires simultaneously. This is
accomplished by having the room switch leg power
activate the Emergency Power Control, EPC-1-M.
Wire input #1 or #2 and neutral are connected inter-
nally to a sensing circuit. During a power interrup-
tion on the sensing input, this circuit causes
contact X to drop into a N.C. position and turns on
the emergency load(s). Review wiring diagram, on
reverse, for details.
