IMPORTANT SAFEGUARDS
When using electrical equipment, basic safety
precautions should always be followed, including
the following:
READ AND FOLLOW ALL
SAFETY INSTRUCTIONS
All servicing should be performed by qualified
personnel only.
Do not mount near any heat producing equipment.
Equipment should be mounted in locations and at
heights where it will not be readily subjected to
tampering by unauthorized personnel.
The use of accessory equipment not recommended
by the manufacturer may cause an unsafe condition.
Do not use this equipment for other than intended
use.
In Class I Division 2 locations, do not replace any
non-metallic hardware with metal hardware.
Contact authorized agent for factory replacement
parts.
In Class I Division 2 areas, install equipment in
accordance with appropriate NEC articles plus any
other applicable codes.
To avoid static discharge, do not attach any
ungrounded metal hardware to the enclosure.
Do not store or place flammable materials near
lamp. Install only grounded wiring systems to
supply this equipment
CAUTION – ensure lamp heads are positioned
so they are aimed below horizontal

INSTALLATION AND OPERATING
INSTRUCTIONS
Do not use this equipment outdoors.
CAUTION: Halogen cycle lamp(s) are used in this
equipment. To avoid shattering: Do not operate
lamp in excess of rated voltage, protect lamp
against abrasion and scratches and against liquids
when lamp is operating, dispose of lamp with care.
Halogen cycle lamps operate at high temperatures.
Do not store or place flammable materials near lamp.
CAUTION: “To avoid electrical overload, total
connected lamp load (factory and field installed)
should not exceed output rating”.
Free installation area of hazardous atmospheres
before wiring equipment or servicing, this reduces
the risk of accidental explosion due to inadvertent
battery shorting during installation.
SAVE THESE INSTRUCTIONS
WARNING – Shut off AC power to branch
circuits to which units will be connected. All
wiring should be per NEC wiring methods
for Hazardous locations.
To maintain warranty, equipment with
batteries must be installed or placed on
charge within prescribed period after
shipment.

5. Connect Battery leads to the battery or batteries (See Figure 5).
6. Adjust head(s) as follows: (See Figure 4).
a. Rotation – Loosen head nut and rotate head to desired position. Retighten head nut. An antirotation screw has been
provided to ensure proper rotation.
b. Angle – Loosen thumb screw passing through head swivel sufficiently to allow internal teeth to disengage. Position
head to desired angle.
c. Retighten both head nut and thumb screw.
CAUTION – ensure lamp heads are positioned so they are aimed below horizontal
7. A dual load terminal block is provided for lamp hook-up. Ensure total wattage of heads, both unit mounted and remote (if
applicable), does not exceed unit rating. Factory mounted lamps are wired to the terminal block at points L+ and L-.
All remote loads should be wired to the terminal block at RL+ and RL- (See Figure 2).
Use wire gauge that limits voltage drop to an acceptable level (See page 6)

SELF-DIAGNOSTICS SYSTEM OPERATION
(EMERGENCY OPERATION UNITS ONLY)
Normal Power-Up Sequence
At power-up, the red and green LED indicators will alternately flash for one to two seconds. Next, the unit will go through a
“Power-Up Quick Test” with the green LED flashing quickly. If no power-up faults were detected, the green LED will then
flash slowly for up to 36 hours to indicate that the battery is charging. If any faults were detected during the “Power-Up
Quick Test”, these will be indicated by a flashing red LED indicator (see below for interpretation of flashing sequences).
The red LED may be accompanied by a buzzer. This buzzer may be disabled by a short press of the test switch or by the
“SILENCE ALARM” button on the remote tester and will remain disabled for a period of 196 hours. After the fault has been
corrected, the red LED flash and buzzer will be cleared automatically and the unit will return to normal operation except in
the case of lamp failure. Once relamping has been completed, perform a manual test to clear the fault.
Lamp Load Calibration
Once energized, the unit waits 36 hours while the batteries are charged. Then performs an automatic lamp load calculation
only once during initial startup. The system will detect a 10% or more of total load loss and will indicate a lamp failure.
Replace lamps as required. Upon lamp replacement and resetting the fault condiation, the system will return to normal
operating status.
Manual Calibration: If, after installation and calibration, lamp load is increased or decreased the system will need to be
manually calibrated for the new load. To re-calibrate, press the test switch four consecutive times. Lamp re-calibration
can also be accomplished with the optional remote control by pressing in sequence, 'Silence, Silence, Cancel, Silence'.
The lamps will illuminate for a period of 30 seconds during the calibration process and then the unit will return to normal
operation status. Manual calibration can be performed at any time after 36 hours of charge or when the indicator status
light is solid green.
Emergency Opration
Emergency operation occurs when AC power fails. The unit remains in this mode until AC power is restored. During
emergency operation, both red and green LED indicators are disabled. Upon restoration of AC power, the green LED will
flash for up to 36 hours to indicate that the unit is in battery charging mode. Allow 72 hours for the battery to fully charge.
User Interface
Green LED Indicator
•Steady On – AC power is present and battery is fully charged
•Slow Flash – Battery charging
•Fast Flash – Unit is performing an automatic or manually initiated self-test
Red LED Indicator
•Single Flash – Battery fault
•Double Flash – Lamp failure
•Triple Flash – Charger fault
•Quad Flash – Emergency transfer failure
(If more than one fault condition is present simultaneously, the red LED will flash each fault pattern in sequence, and then
repeat)
Red and Green LED Indicators Together
•Slow flashing red and green – Low line voltage
•Fast flashing red and green – High line voltage
Pushbutton Test Switch
•Long Press (over 0.5 seconds) – Transfers unit to emergency (battery) operation as long as button is depressed
•Short Press – Initiates various self tests
oOne Press – Cancel any self-test currently running
oTwo Presses – Start 1 minute self-test
oThree Presses – Start 90 minute self-test
oSeven presses – Forces a complete system reset
(The unit will allow up to seven 1 minute tests during the first 24 hours of operation. Allow at least 24 hours for battery
charging before performing any extended amount of testing)
Buzzer – Sounds in unison with the flashing red LED if a fault is detected. May be disabled for up to 196 hours by a short
press of the test switch.

WIRING CALCULATIONS FOR VOLTAGE DROP PROTECTION
IN EMERGENCY LIGHTING SYSTEMS
TO DESIGN A PROPER EMERGENCY LIGHTING SYSTEM, CIRCUIT RUNS MUST BE OF SUFFICIENT SIZE TO MAINTAIN A PROPER
OPERATING VOLTAGE TO ALL LAMPS. MAXIMUM ALLOWABLE VOLTAGE DROP SHOULD NOT EXCEED 5%. PROPER WIRE SIZE
IS DETERMINED FROM THE FOLLOWING FORMULA, TABLE AND EXAMPLE SHOWN BELOW.
L = CM x EI CM= I x 22 x L
I x 22 EI CM = WIRE SIZE IN CIRCULAR MILLS
I = LOAD IN AMPERES (EMERGENCY MODE)
L = LENGTH OF WIRE RUN. (UNIT TO REMOTE LOAD)
EI = I x 22 x L I= CM x EI EI = MAXIMUM ALLOWABLE VOLTAGE DROP. (5%)
CM L X 22
USING THE ABOVE FORMULA AND HAVING CALCULATED THE CIRCULAR MILLS REQUIRED TO CARRY THE SPECIFIED LOAD AT
A PREDETERMINED AND ALLOWABLE VOLTAGE DROP, THE FOLLOWING CHART WILL IDENTIFY THE NECESSARY WIRE GAUGE
FROM THE CORRESPONDING CIRCULAR MILL SIZE LISTED.
WIRE GAUGE AMPERE CAPACITY OHMS PER 1000 ft CIRCULAR MILL SIZE
12 20 1.586 6,530
10 25 .9972 10,380
8 35 .6271 16,510
6 50 .3944 26,250
4 70 .2480 41,740
EXAMPLE: WHAT SIZE SHOULD BE USED FOR A 6-VOLT CIRCUIT TO TRANSMIT A CURRENT OF 4 AMPERES A
DISTANCE OF 75 FEET WITH A VOLTAGE DROP OF NOT MORE THAN 5%?
EI = MAXIMUM ALLOWABLE VOLAGE DROP 5% OF SELECTED VOLTAGE:
USING 6 VOLTS x .05 = .3 VOLTS.
USING THE FORMULA AND SUBSTITUTING THE GIVEN QUANTITIES:
CM = 4 x 22 x 75 = 22000 CIRCULAR MILLS NEEDED. (USE #6 WIRE)

NOTE: SMALLEST PERMISSIBLE WIRE SIZE FOR SYSTEMS UNDER 50 VOLTS IS #12 FOR EMERGENCY LIGHTING EQUIPMENT
