Engineering reference
Choosing the right EX-ES03 configuration.
Start with the duty — emergency, exit, or both — since that selects the configuration. Then confirm the legend colour and any directional arrows, and check the input voltage, which differs between configurations and includes a 12 to 48 V DC option on the combination unit.
EX-ES03 is the only fixture in the catalogue that is both classified and code-mandated: UL844 for the hazardous location and UL924 for egress. The four configurations separate emergency light, exit sign and combination duty, with the combination unit running the two systems independently.
Common questions
Frequently asked questions
These answers clarify the selection process without replacing project-specific documentation.
What configurations are documented?
Four: emergency light only, emergency and exit combination, exit sign only, and a further variant. The combination unit runs its emergency and exit systems independently, each with 3 hour backup.
What legend options are available?
Red or green letters with directional arrows on the exit and combination configurations. The emergency-only configuration carries no legend.
Why does this appear under both explosion proof and emergency?
It satisfies both requirements — UL844 for the classified area and UL924 for egress — in one unit, specified in full below.
