Battery backup duration ensures that combo exit signs remain illuminated during power outages, which is essential for safety and code compliance. The standard minimum duration is 90 minutes, which is generally sufficient for most emergency situations and meets code requirements such as UL924. All listed products, including the Standard Light pipe LED Exit & Emergency Combo - Red Lettering with White Housing Color and Low Profile All LED Exit & Emergency Combo, Selectable Red/Green, White Housing, provide a 90-minute battery backup. This consistent offering across products means you can rely on any of these models to provide safety and compliance during emergencies.
