Self Diagnostics Testing:
Important Note: Emergency lighting systems should be
tested as often as local codes require, or at least monthly, to
ascertain that all components are operational. Allow battery to
charge 24 hours before initial testing, and 168 hours to fully
charge battery. Note: The self-diagnostics option performs
tests to satisfy these test requirements, as well as local code
testing requirements for most areas.
Status Indicator
1. Normal Operation: When unit is functioning properly,
with A.C. power supplied, the status indicator will be green and
the exit lamp will be on.
2. Testing: When the status indicator is flashing green with
the exit lamp on, a test is in process. The exit performs two
types of tests. Every 28 days (+/- 2 days) it performs a monthly
test. The monthly test is a five minute diagnostics test of the
battery, lamp(s), and charging circuit. Upon completion of the
five minute test, the status indicator should return to green
(steady) to indicate a properly functioning unit. A flashing red
status indicator indicates a failure condition. Every 6 months (+/
- 12 days) self-diagnostics performs a 6 month test. The 6
month test is a 30 minute diagnostics test of the battery,
lamp(s), and charging circuit. After the 30 minute test, the
status indicator should return to green (steady) to indicate a
properly functioning unit. A flashing red status indicator
indicates a failure condition.
3. Failure Indication: When the status indicator is flashing
red, the exit needs service. The self-diagnostics system has
detected a low battery, bad lamp(s), or a charger circuit failure.
At this time the exit failure should be diagnosed and serviced by
quailified personnel.
Note:
Turn off A.C. power and disconnect battery before
servicing unit.
Refer to the Maintenance section of these instructions when
replacing parts.
After the unit has been serviced, and continuous power applied
to the unit, the diagnostic systems clock will reset. This will be
indicated by the status indicator being green, and the exit lamp
being on.
Maintenance:
Note: Turn off A.C. power and disconnect battery before
servicing unit.
Lampboard Replacement:
1. Disconnect lamp connector
m
, and test switch/status
indicator connector
k
(if applicable). Remove (4) screws
holding lampboard
i
in place and remove lampboard.
Lampboard replacement is a reverse sequence of above.
Battery Replacement
1. Cut cable tie holding battery
d
to bracket. Pry battery from
battery bracket to release from tape. Replacement is a
reverse sequence of above.
Charger P.C. Board Replacement:
1. Cut tape and open enclosure box for Charger P.C. Board.
Disconnect lamp connector, and test switch/status light
connector.
2. Cut installation supply leads and charger board/self-diagnos-
tics connections
n
at pushnut connector
c
. Strip installation
supply leads and self-diagnostics leads for pushnut connec-
tion.
3. Charger pc board replacement is a reverse sequence of
above.
Manually Clearing a Failure:
A failure indication may be cleared manually by:
1. Placing the unit in the manual test mode for more than 30
seconds.
2. Removing AC power for more than 30 seconds.
If a failure condition is detected during the next self-diagnostics
test, the failure indicator will flash red, indicating a failure
condition.
Manual Testing:
Important Note: The self-diagnostics option performs test to
satisfy local codes in most areas. Although self-diagnostics
does not allow a manually initiated self-diagnostics test, there
are two methods to simulate an AC power failure and initiate a
test of the battery, lamp(s), and charger circuit:
If desired, manual testing of the unit may be actuated as
follows:
1. Hold the magnet to the magnetic test zone. The status
indicator will go out when the magnet is positoned correctly,
indicating the manual test mode has been activated. Remove
the magnet to end the test and return the unit to normal
operation. The status indicator should return to green, indicating
a properly functioning unit.
2. Press the manual test switch (located inside the unit on the
lampboard). The status indicator will go out to indicate the
manual test mode has been activated. Release the test switch
to end the test and return the unit to normal operation. The
status indicator should return to green, indicating a properly
functioning unit.
