Disclosed is a hazard detection system having: a visual alarm device (VAD) including a VAD controller which is an electronic controller, the VAD controller controlling a plurality of implements within the VAD including a light source, and a luminosity sensor with which the VAD controller is configured to perform a VAD health test to confirm that a plurality of parameters of the light source meet or exceed threshold requirements, the plurality of parameters including luminous intensity and luminous profile, wherein the VAD is configured to perform steps including: monitoring for a trigger event to perform the VAD health test, the trigger event including the occurrence of an alarm a condition; activating the light source upon determining that the trigger event has occurred; monitoring the plurality of parameters to determine whether the light source meets or exceeds threshold requirements, and communicating an outcome of the VAD health test.

A control panel for a fire alarm control system is described herein. In some examples, one or more embodiments include a memory and a processor to execute instructions stored in the memory to receive a fault signal from a thermographic detector device, wherein the fault signal corresponds to a fault associated with the thermographic detector device, wherein the fault signal is associated with at least one of a field of view fault, an operating parameter fault, an internal fault, and a transmission fault, and provide a notification of the fault using the fault signal.

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.

Methods and apparatus relating to functional safety critical audio system for autonomous and industrial applications are described. In an embodiment, safety island logic circuitry transmits an enable signal to cause initiation of a functional safety test for an audio component in a vehicle. Audio processing logic circuitry receives the enable signal and causes activation of power amplifier logic circuitry, in response to the enable signal, to drive the audio component in accordance with an audio alert test signal. The audio component includes a Parametric Acoustic Array (PAA) transducer. Other embodiments are also disclosed and claimed.

An emergency lighting system provides testing and reporting functionality in a rapidly repeatable fashion for environments with numerous emergency lighting units. In one or more embodiments, the emergency lighting system comprises a plurality of emergency lighting units capable of conducting one or more tests and reporting their operating condition as test results. One or more terminals receive and aggregate the test results and present the same to a user. Emergency lighting units having an undesirable operating condition can then be readily identified and addressed.
