An emergency lighting system that includes a storage device, an emergency lighting device, an area control device and an external device. The emergency lighting device includes a light, a first controller having a first electronic processor configured to perform a self-diagnostic test, and a first input/output (I/O) device configured to transmit data associated with the self-diagnostic test. The area control device includes a second I/O device configured to receive data associated with the first self-diagnostic test form the first I/O device and transmit the data associated with the self-diagnostic test to the storage device.

Devices, systems, and methods for public address system action auditing are described herein. In some examples, one or more embodiments include a computing device comprising a memory and a processor to execute instructions stored in the memory to access an event log associated with an event in a facility, compare the event log with a predefined configuration file associated with a public address system of the facility, and generate a report about the event based on the comparison.

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.

Aspects of the invention are directed towards method system and devices assisting the configuration, installation and maintenance of the devices in a system. The invention describes integrating a digitized map on a user terminal. The digitized map comprises positions for configuring one or more devices. The user terminal receives position co-ordinates and configuration information of each of the one or more devices. The user terminal requests configuration for one or more devices and receives the configuration based on the configuration information. The received configuration is transmitted to the one or more thereby configuring the one or more devices.

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.

The present invention relates to a device for generating sound messages, comprising: a generation chain configured to generate a first and a second sound signal carrying a useful audio signal and a test audio signal; a conversion chain configured to transform the first and second sound signals into first and second analog signals; and a verification chain configured to extract the test audio signal from a combination of the analog signals to verify the integrity of the useful audio signal.
The first sound signal corresponds to the sum of the test audio signal and the useful audio signal, and the second sound signal corresponds to the sum of the test audio signal and an opposite signal corresponding to the opposite of the useful audio signal.

Devices, systems, and methods for event device maintenance are described herein. In some examples, one or more embodiments include a mobile device comprising a user interface, a memory, and a processor to execute instructions stored in the memory to receive an inventory including a group of event devices, generate a device identification analysis for the group of event devices, display on the user interface the device identification analysis, receive an input for an event device of the group to take an audit action, and initiate the audit action to be taken by the event device of the group in response to the input.

Aspects of the invention are directed towards method system and devices assisting the configuration, installation and maintenance of the devices in a system. The invention describes integrating a digitized map on a user terminal. The digitized map comprises positions for configuring one or more devices. The user terminal receives position co-ordinates and configuration information of each of the one or more devices. The user terminal requests configuration for one or more devices and receives the configuration based on the configuration information. The received configuration is transmitted to the one or more thereby configuring the one or more devices.

The disclosure generally provides methods, systems and apparatus for functional safety systems. Specifically, the disclosure relates to validating functional safety warnings that may be communicated to an operator. Such warnings may include safety warning chimes. An exemplary embodiment relates to an apparatus to validate operation of a Functional Safety (FuSa) platform through delivery of a safety warning signal, the apparatus comprising: a Safety Application to issue a safety warning signal, the safety warning signal configured for audio delivery to an audience; a transmit path in communication with the Safety Application to transmit the safety warning signal; and a digital signal processing (DSP) circuitry to communicate with the transmit path, the DSP circuitry configured to detect the safety warning signal at the transmit path, the DSP circuitry further configured to communicate the detected safety warning signal back to the Safety Application; wherein the transmit path, the Safety Application and the DSP circuitry are integrated on a System-on-Chip (SoC).

A testing device for emergency lighting equipment including a main control unit and at least one control module, where each of the at least one control module is used to check operational readiness of an emergency lighting device, and the main control unit and the at least one control module are all connected to a network to form a control system for a smart phone or a building security monitoring system to perform a remote inspection operation on at least one aforementioned emergency lighting device via the network.
