TECHNICAL DATA
UMX EXITS
UMX201 – UMX208 Lead Calcium=18W for 1 1/2 hrs.; 15W for 2 hrs.
UMX101 – UMX108 Lead Calcium=27W for 1 1/2 hrs.; 24W for 2 hrs.
UMX221 – UMX228 Nickel Cadmium=15W for 1 1/2 hrs.; 12W for 2 hrs.
Lamps
Two F6T5 fluorescent lamps
provide long life and normal
mode illumination of the
lens. Two 6V, 6W DC lamps
illuminate the face panel in
the emergency mode.
Housing Construction
The Sure-Lites UMX Series
incorporates a rugged
enclosure of moisture and
corrosion resistant industrial
grey fiberglass with a durable
polycarbonate lens. Housing
is fully gasketed. A breather
vent permits ventilation of
internal pressure from gases
released by charging batteries.
UMX Series Exits are suitable
for surface mounting only. Wet
Location Listed for operation in
ambient temperatures above
32°F. Optional Thermal Heater
available to facilitate use
in unheated areas where
battery performance would
be diminished due to low
temperature operation.
Line-Latched
Sure Lites’ line-latched
electronic circuitry makes
installation easy and
economical. A labor efficient
AC activated load switch
prevents the lamps from turning
on during installation to a
non-energized AC circuit.
Line-latching eliminates the
need for a contractor’s return
to a job site to connect the
batteries when the building’s
main power is turned on.
Solid-State Charger
Supplied with a 120/277 VAC,
voltage regulated solid-state
charger. Immediately upon
restoration of AC current after
a power failure, the charger
provides a high charge rate.
The charge circuit reacts to the
condition of the battery and
alters the rate of charge in
order to maintain peak battery
capacity and maximize battery
life. Solid-state construction
recharges the battery following
a power failure in accordance
with UL 924.
Overload and Short
Circuit Protection
The solid-state overload
monitoring device in the DC
circuit disconnects the lamp
load from the battery should
excessive wattage demands
be made and automatically
resets when the overload or
short circuit is removed. This
overload current protective
feature eliminates the need
for fuses or circuit breakers
for the DC load.
Brownout Circuit
The brownout circuit on Sure-
Lites’ exits monitors the flow
of AC current to the exit and
activates the emergency
lighting system when a
predetermined reduction of
AC power occurs. This dip
in voltage will cause most
ballasted fixtures to extinguish
causing loss of normal lighting
even though a total power
failure has not occurred.
Solid-State Transfer
The UMX Exit incorporates
solid-state switching which
eliminates corroded and pitted
contacts or mechanical failures
associated with relays. The
switching circuit is designed to
detect a loss of AC voltage and
automatically energizes the
lamps. Upon restoration of
AC power, the emergency
lamps will switch off and the
charger will automatically
recharge the battery.
Test Switch/Power Indicator
Light
Conveniently located rubber
booted Test Switch allows for
manual verification of proper
operation of the transfer circuit
and emergency lamps. A sealed
light emitting diode (Power
Indicator Light) provides visual
assurance that the AC power
is on.
Sealed Lead Calcium Battery
The fully sealed, long-life,
maintenance-free, lead calcium
battery is ideal for emergency
lighting applications. These
batteries typically provide 8 to
10 years of life and may be
operated in any position.
Sealed Nickel
Cadmium Battery
Sure-Lites’ sealed nickel
cadmium batteries are
maintenance-free with a life
expectancy of 15 years. The
sealed rechargeable nickel
cadmium battery offers high
discharge rates and stable
performance over a wide range
of temperatures. The specially
designed resealable vent
automatically controls cell
pressure, assuring safety and
reliability. This battery is best
suited for harsh ambient
temperatures because the
electrolyte is not active in the
electrochemical process.
Warranty
All Sure-Lites’ products are
backed by a firm one-year
warranty against defets in
material and workmanship
(excluding lamps). Maintenance-
free, long-life, sealed lead
calcium batteries carry a
five-year, pro-rata warranty.
Maintenance-free, long-life,
sealed nickel cadmium batteries
carry a fifteen-year pro-rata
warranty.
