Application
The UL924 Listed Emergency Power Control EPC-THPH, is a 3 phase power loss sensing device
with Form C Dry Contact.
Fire Alarm / Remote Test Switch - Some applications demand that emergency lighting be activated
upon fire alarm, security alarm, or remote test switch activation. The EPC-THPH is equipped with a low
voltage override input (red jumper). Please visit www.lvscontrols.com/FAI.php for details
Three Phase Sensing - Can be selected to sense 1 or 3 phase normal power systems for interruption.
Small Form Factor
Dry Status Contact - Form C dry contact permits interconnection with BMS and other systems indi-
cating the state of the emergency system and normal power.
Recommended Box Size 4-11/16” with extension
(total depth 4” minimum)

Installation
In order to install the EPC in accordance with national/local code requirements, a qualified electrician
should review & understand the installation instructions. Check voltage & current requirements.
Verify & lock out circuit breakers on both regular (utility) power & 24 hour emergency generator or
inverter circuit. Install a self-adhesive 2" x 3" caution label in each fixture or load controlled by an EPC
cautioning that the load is supplied from 2 different power sources, normal & emergency. Review
wiring diagram & connect wires, one at a time, in accordance with the numeric identification.
Setup/Programming
Turn on Normal/Emergency power sources.
Initial Testing
In order to test that the wires are connected correctly, without any inconvenience to occupants, do
not turn off regular (utility) power off until you have checked each device as follows:
1) Check that regular branch circuit breaker is connected & utility power is available. Green LED on
If green LED is not lit, check connections & continuity to branch circuit breaker. If using 3 phase
sense mode, ensure power is applied to all 3 phases. If using 1 phase only, connect Orange Brown
Yellow wires together.
2) Check that emergency branch circuit breaker is connected & emergency power is available. Red
LED should be lit. If red LED is not lit, check connections & continuity to emergency branch circuit
breaker.
4) Emergency Operation Test: Press and hold test button, dry contact should change position.
Maintenance
No maintenance is required to keep the EPC functional. However, regular testing should be
performed when the lamps or ballasts have been replaced or when remodeling has taken place.

CONTACT *
Note: Dry status contact is
shown in emergency state. It
can be used for BMS and other
remote control purposes. If
unused, cap #7,8,9 leads.
Note: if emergency power is
unavailable - normal power
may be hooked up to #1/#2.
However, red LED will not
supervise EM power.
Note: if only 1 phase sensing is required,
connect orange, brown, and yellow wires
together - or use LVS model RRU-UNV.
Red Fire Alarm Loop
Consult factory for wiring details
Blue time delay loop (cut to disable)
Note: When blue wire is un-cut there is a 2.5 second time delay when normal power is restored before dry status contact
changes staets. Cut blue jumper and cap o leads to disable time delay.
