OPERATING INSTRUCTIONS
APPLICATIONS
Mighty Mac MMEX series, Millenium Metrex METDU, METSR, METSU, METSW series, SimpleSeal CMEXR series exit signs
with EL or CEL Emergency Battery Pack options. See fixture labels for instructions. METSW unit shown, other units similar.
FEATURES
-
Sealed, maintenance-free nickel-cadmium battery. EL option is suitable for use in 10 C (50 F) to 45 C (113 F) environments.
CEL option includes a thermostatically controlled battery warmer and is suitable for use in -45 C (-49 F) to 45 C (113 F)
environments. Self-testing circuitry automatically conditions the battery and performs regularly scheduled tests that conform
to NFPA 101 Life
-
Safety Code. Self-diagnostic circuitry monitors battery, charger, power transfer and lamp functions.
INSTALLATION
-
Follow Kenall Installation Instruction Sheet for proper mounting,
assembly and wiring of unit.
-
Fixture is shipped with battery disconnected.
-
After installing electrical chassis and making field wiring connections (AC
power OFF), connect polarized 2-pin battery connector to PC board
assembly.
-
Exit legend will illuminate for a few seconds and then extinguish. This
signals that the battery is properly connected and is protected from
discharging until AC power is established.
-
Carefully align front stencil assembly over status/test pushbutton and
indicator. Snap front stencil assembly to housing.
START-UP
-
Do not apply power to fixture unless supply can be maintained for at least 7 days without interruption.
-
If battery is not connected when power is applied, the self-diagnostic feature will detect the missing battery and the status
LED will display a steady red signal. Connect the battery and reset the system by pressing and holding the manual push test
switch for approximately 7 seconds.
-
Upon initial power-up, the fixture will supply a trickle charge to the battery for 90 minutes. Then it will switch to full charge
mode for approximately 24 hours. The fixture will then condition the battery with a pair of 90 minute discharge and 24 hour
recharge cycles.
LOAD LEARNING
-
During the final discharge/recharge cycle of the battery conditioning function, the self-diagnostic feature will measure the
operating current of the internal and external (if equipped) exit sign(s).
-
Any time the total (internal or external) exit sign load is intentionally altered, the system must be reset by pressing and
holding the manual test pushbutton for approximately 7 seconds. Failure to do so will result in a lamp fault indication.
NORMAL OPERATION
Normal operation is indicated by a steady green signal from the status LED. This indicates the fully charged battery is receiving
a maintenance (trickle) charge and normal AC power is present. The normally on exit sign(s) will operate from normal AC power
