Edge Lit Universal Red/Green LED Combo Exit Sign | Adjustable Angle | Wall, Ceiling, and Side Mount

Construction

The COELRT-U Edge Lit Combo Exit Sign housing is constructed from injection-molded thermoplastic housing with an etched, clear acrylic panel. Double sided panel comes as mirrored configuration. Lettering is 6” high with 3/4” stroke. Housing color options are  black and white.

Illumination

The COELRT-U Combo Exit Sign Series delivers reliable, long-lasting LED illumination with a high-output LED board featuring both red and green options (with red set as the default). Equipped with two fully adjustable LED lamps, the unit provides a bright 460 lumens in battery mode, ensuring dependable emergency lighting when it’s needed most.

Emergency Operation

Upon failure of the normal utility power, an internal solidstate transfer switch automatically provides uninterrupted emergency operation for at least 120 minutes. The fully automatic solid-state, two-rate charger initiates battery charging to recharge a discharged battery in 24 hours.

Battery - Battery Backup

The COELRT-U series is designed with a 3.2V 3200mAh maintenance-free LiFePO4 battery providing a battery run-time of 120 minutes. With LiFePO4 batteries, safety is paramount – their formulation, lithium iron phosphate, is highly resistant to overheating and fire hazards. They are backed by an integrated battery management system (BMS) to prevent overcharge, over-discharge, and short-circuiting, ensuring peace of mind for users. Recharge time of the battery is 24 hours.

Operational Temperature

Photometrics

Total Luminaire Lumens : 460lm

Suggested mounting height of 7.5ft illuminates 1 footcandle (FC) spaced at 42ft for a 3ft path of egress

Mounting height of 10ft illuminates 1 footcandle (FC) spaced at 40ft for a 3ft path of egress

Mounting height of 10ft illuminates 1 footcandle (FC) spaced at 38ft for a 6ft path of egress

Disclosure:

Spacing is measured in lab condition with an assumed open space, no obstruction and reflection rates of 80 (ceiling) / 50 (walls) / 20 (floor). Actual spacing may vary depending on what environment the fixture is installed in.

Self-Testing Option

This unit continuously self-checks for proper operation, with a multi-color LED indicator light that displays status conditions and updates automatically when corrected. The unit is **field-selectable for either self-testing or manual testing mode**, giving flexibility for different maintenance preferences. In self-test mode, the unit will automatically perform tests in emergency operation for up to the full 120-minute duration to ensure reliability during an actual power failure. In manual mode, tests can be initiated at any time using the external push-button test switch.

Electrical Components

The unit operates with a universal input voltage of 120–277VAC, 50/60Hz, ensuring compatibility with a wide range of installations. An LED display indicates AC/ON status, while an external push-button test switch and charge indicator allow maintenance personnel to quickly verify operational performance. Powered by a Lithium Iron Phosphate (LiFePO₄) battery, the system has a 24-hour recharge time and automatically switches to trickle charge once fully charged. The advanced circuit design includes brownout transfer, low-voltage battery disconnect, overload and short-circuit protection, and solid-state transfer for maximum reliability and safety.
