How long does the emergency battery backup last?

All Jarvis emergency backup fixtures provide 90 minutes of illumination during power failure, which is the minimum duration required by IBC (International Building Code) and NEC (National Electrical Code) for life safety egress lighting. The battery charges automatically during normal AC operation and activates instantly on power loss — no manual intervention required.

Do I need a separate emergency inverter with Jarvis backup fixtures?

No. The WPFT-E and AL-EMER wall packs have the emergency battery integrated directly into the fixture housing. This eliminates the need for a separate emergency inverter, remote battery pack, or dedicated emergency circuit — simplifying installation and reducing per-opening cost on projects where both general illumination and emergency egress lighting are needed at the same location.

Can the WPFT-E wall pack serve as both general lighting and emergency lighting?

Yes. During normal operation, the WPFT-E functions as a standard forward-throw LED wall pack at 25–103W selectable wattage. When AC power fails, the integrated battery activates and provides emergency-level illumination for 90 minutes. This dual-function approach means one fixture satisfies both the general exterior lighting requirement and the emergency egress lighting requirement — eliminating the need for a separate emergency-only fixture at that location.

What building codes require emergency lighting?

IBC Section 1008 requires illuminated exit signs and emergency egress lighting in commercial buildings, with a minimum of 1 foot-candle at floor level along exit paths and 90-minute battery duration. NEC Article 700 covers the electrical requirements for emergency systems. Most jurisdictions adopt IBC and NEC with minimal amendments. Specific requirements vary by occupancy type and local code adoption — consult the AHJ (Authority Having Jurisdiction) for your project location.
