Abstract: The subject disclosure relates to power failure simulations, for example to test lighting systems, such as emergency lighting units or lighted signage. In some aspects, a pressure monitoring process of the disclosed technology can include steps for receiving a plurality of differential pressure measurements from the pressure sensor, determining whether to transmit pressure information to a management system based on at least two differential pressure measurements received from the pressure sensor, and transmitting the pressure information to the management system if a difference between the at least two differential pressure measurements exceeds a predetermined threshold. Systems and computer-readable media are also provided.

Abstract: The subject disclosure relates to solutions for testing lighting systems and in particular, for verifying lighting system operability in the event of a power failure. A process of the disclosed technology can include steps for receiving an interrupt command, toggling an interrupt relay in response to the interrupt command, and measuring one or more lighting characteristics of the lighting array to determine if the second power supply can power the lighting array. Systems and machine-readable media are also provided.

Abstract: The subject disclosure relates to an emergency lighting system for simulating power failure in an emergency lighting system. In some aspects, the system includes an interrupt relay coupled between a first power supply and a lighting array, a power monitoring module coupled between a second power supply and the lighting array, and a wireless transceiver configured for transacting data with a wireless backhaul gateway. Additionally, the lighting system can include a microcontroller configured to perform operations for receiving an interrupt command from the wireless backhaul gateway, toggling the interrupt relay in response to the interrupt command, wherein toggling the interrupt relay terminates power delivery to the lighting array, and measuring one or more power characteristics of the second power supply to determine if the second power supply can power the lighting array. Methods and machine-readable media are also provided.
