The EXIS lighting system installed on Sikorsky S76 aircraft is an emergency escape lighting system that highlights the pilot, co-pilot, cabin doors and popout windows. This reliable Heli-One design provides illumination of emergency exit doors and windows for at least 10 minutes following activation, giving the passengers enough time to evacuate the aircraft in case of emergency. Using Locktite brand ‘electroluminescent’ lighting strips, the system supplements the OEM emergency lighting system. The lighting strips around the pilot door, co-pilot door and the windows each have their own power supply that consists of a rechargeable battery and an inverter. The power supplies are connected to the DC Essential bus through a control switch and 1 Amp circuit breaker. Meanwhile, the lighting strips around the sliding cabin doors (if needed) are powered by a self-contained system – this is powered using a non-rechargeable battery pack and inverter with water activated switch. The system uses the original factory installed emergency lighting switch with the same functionality
