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 onl y. 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.

Sure Lites’ line-latched electronic circuitry makes installation easy and economical. A labor efficient AC activated load switch prevents the lamps from turnin g 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 .
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.

C i r c u i t P r o t e c t i o n
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.
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.
S o l i d - S t a t e Tr a n s fe r
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.
Te s t S wi t c h / P o w e r I n d i c a to r L i g h t
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.
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.

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.
Wa r r a n t y
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 warrant y. Maintenance-free, long-life, sealed nickel cadmium batteries carry a fifteen-year pro-rata warranty.
