Spectron Electronics
All N4X/N4XP models with the Spectron provide:
■ Visual indication of AC power status
■ Visual indication of all self-diagnostic test cycles
■ Visual indication of unit malfunctions including:
• Batteryfault
• Chargerfault
• Transferfault
• Lampfault
■ User initiated test cycles of 1, 5, 30 or 60 minutes
■ Temperaturecompensatedchargerforlongerbatterylife
■ 15 minute retransfer delay
LED Indicators
Two status indicators, one red and one green are provided on the
control panel of all models equipped with the Spectron option.
Red Service Alert LED
Under normal operating
conditions, the Service
Alert LED indicator will
remain off. In the event the
Spectron Controller
detects a malfunction, the
Service Alert LED will blink at
a 1 Hz. rate based on the
following table:
SERVICE ALERT CODES
● = battery disconnected
● - ● = battery fault
● - ● - ● = charger fault
● - ● - ● - ● = transfer fault
● - ● - ● - ● - ● = lamp fault
Lamp Sensing Adjustment
Models N4X2I/N4XP2CVS
These models are shipped without remote xture capacity: the
lamp sensing circuitry is factory-set. No further adjustments
required.
All other N4X Spectron and N4XPCVS
Series Models
Liteforms N4X Spectron and N4XPCVS Series remote capacity
models provide sufcient battery power to operate the unit’s
two integral lighting heads plus one or more remote lighting
xtures. In order for the Spectron electronics module to
detect a lamp failure in any of the connected xtures, the lamp
sensing circuit must be adjusted.
Procedure:
1. With a small screwdriver, turn the Lamp Sense Adjust
potentiometer fully clockwise.
Refer to Fig. 1, below.

Red Status LED Code Description
One blink ON/pause Battery not connected
Two blinks ON/pause Battery fault
Three blinks ON/pause Charger fault
Four blinks ON/pause Transfer circuit fault
Five blinks ON/pause Emergency Lamp fault
Green Operating Status LED
The green Operating Status
LED serves as both an AC
power and a self-test
indicator. During normal
operation, the Operating
Status LED will be illuminated indicating the presence of AC
power. During all automatic or manual self-test cycles, the
Operating Status LED will blink at a 1 Hz. rate.

Manual Tests
Using the unit test switch, users can initiate different duration
test cycles based on the following table:
Initiating Action Test Cycle
Press test switch once 1 minute
Press test switch twice 5 minute
Press test switch 3 times 30 minute
Press test switch 4 times 60 minute
Note: Pressingtestswitchatanytimeafteratestcyclehasbegun
cancels remainder of test and returns unit to normal operation.

LED Potentiometer
2. Press the unit test switch once. The emergency lamps
will illuminate and a 1 minute self-test will begin. The green
“Operating Status” LED on the unit’s Spectron control panel
will also begin to ash. The “Lamp Fail” LED located on the
charger board (See Fig. 1) should not be illuminated at
this time.

3. Slowly turn the “Lamp Sense Adjust” potentiometer
counterclockwise until the “Lamp Fail” LED on the
charger board (See Fig. 1) illuminates. Then turn the
adjustment pot back clockwise just slightly beyond the point
where the “Lamp Fail” LED turns off to avoid false failure
indications. At this point, the red “Service Alert” LED on the
unit’s Spectron control panel will begin a repetitive cycle of
ashing 5 times followed by a pause (“lamp fault”
service alert).
4. While the self-test is still in progress, disconnect one of the
emergency lamp wires from the charger board. The “Lamp
Fail” LED on the charger board (See Fig. 1) should turn on.
Reconnect the lamp wire and observe that the “Lamp Fail”
LED goes out. If “Lamp Fail” LED remains illuminated, turn the
“Lamp Sense Adjust” potentiometer fully clockwise and repeat
step 3.
5. Allow the 1 minute self-test to end (or press the test switch
again to cancel self-test cycle).
6. Press the test switch again. Verify that the “Lamp Fail” LED
and the “Service Alert” LED are not illuminated.
Operation
Spectron electronics operation is fully automatic. Accidental
discharge of the unit battery prior to energization is prevented
by an AC lockout circuit. The unit’s green “Operating Status”
LED, located on the Spectron display panel, illuminates to
indicate the presence of AC power. The unit’s red “Service
Alert” LED will blink after application of AC power if the battery
connection is not completed. During normal operation, the
unit’s charging circuit maintains the battery at full capacity
and the Spectron Controller constantly monitors charger
performance. Should the terminal voltage vary from design
parameter values, the unit’s red “Service Alert” LED will blink,
indicating a malfunction of the battery or charger. Upon
interruption of normal AC power, or brownout condition, the
Spectron Controller automatically switches the emergency
lighting load to the battery. Emergency power will be provided
for a minimum of 90 minutes. During emergency operation,
the battery is protected from deep discharge by a low voltage
battery disconnect circuit. Upon return of normal AC power,
a 15 minute retransfer delay holds the unit in emergency
operation mode, allowing utility voltage to stabilize prior to
reconnection. The charger will then begin a recharge cycle.
A temperature-compensated oat voltage type charger is
provided in N4X/N4XP models utilizing Lead-Calcium batteries.
This charger is designed to adjust charging voltage with
changes in ambient temperature to maximize the life and
performance of the unit’s batteries. The charger will bring the
battery to full capacity within acceptable U.L time standards.
The Spectron Controller automatically initiates a one minute
discharge/diagnostic test every 28 days ± 3.5 hours and a
30-minute discharge/diagnostic test every 6 months ± 1 day.
These tests exercise the unit’s battery to optimize its capacity
and allows the Spectron Controller to analyze emergency
operation performance. Any malfunction of the unit’s transfer
circuit or emergency lamps will cause the red “Service Alert”
LED on the unit’s display panel to blink. During normal
operation, all red “Service Alert” LED blinking indications of
unit malfunction remain latched until corrected and retested.
A manual test switch allows a user programmable 1, 5, 30
or 60-minute diagnostic/discharge test at any time. During
all automatic and user initiated self-tests, the unit’s green
“Operating Status” LED will blink to indicate a diagnostic cycle
in process.
NOTE: Self-testing, self-diagnostic models with over 80 watts of capacity require a minimum load of 35 watts
for accurate lamp failure indications.
