A system is provided to prevent the burning of a vehicle or human injury caused by a fire spread from a battery to a vehicle in the event of a fire in the battery. The battery release system includes a controller that outputs a control signal to release a battery pack from a vehicle to separate the battery pack therefrom when the controller determines that a fire occurs in the battery pack. A mounting structure is rotatably mounted to a body frame and supports the battery pack. A locking device is mounted to the body frame and the locking device locks the mounting structure supporting the battery pack to the body frame, and releases the locked state of the mounting structure in response to the control signal of the controller.

A control panel for a fire alarm system includes a microprocessor operable to send and receive data. The microprocessor has a serial peripheral interface with a master port and a slave port. A computing device has a Differential Manchester encoder configured to encode data received from the master port and a Differential Manchester decoder configured to decode frames and send the decoded data to the slave port. A method of sending and receiving data is also disclosed.

Methods and systems for performing a walk test for fire alarm systems using a mobile device are described herein. One fire alarm system, includes a system control panel fixedly positioned within a building for controlling a plurality of fire alarm system devices connected to the panel and positioned within the building, a mobile device wirelessly connected to the control panel, and a fire alarm system control application on the mobile device, wherein the fire alarm control system application gains access to the control panel and, therethrough, the plurality of fire alarm system devices and wherein the fire alarm control system application issues a command to a particular fire alarm system device of the plurality of fire alarm system devices to perform a particular test or maintenance function and the control panel relays the command to the particular fire alarm system device.

According to one embodiment, a method, computer system, and computer program product for diagnosing one or more blast injuries of an individual based on sustained blast exposure is provided. The present invention may include identifying the presence of a blast event, monitoring the location of an individual for the duration of the blast event; determining a blast exposure associated with the blast event for the individual; determining a sustained blast exposure of the individual comprising the blast exposures associated with a plurality of blast events during a single, continuous period of time; and, responsive to the sustained blast exposure of the individual exceeding one or more threshold values, prompting the individual to seek medical attention for one or more blast injuries associated with the one or more threshold values.

The present disclosure is directed to systems and methods for automatically determining compliant operation of a power supply panel integrated in a fire alarm system, the method including the steps of receiving a first input in a first selectable field relating to a manufacturer type of the fire alarm system; receiving a second input in a second selectable field relating to a circuit class associated with circuits of the fire alarm system; receiving a third input in a third selectable field relating to an end-of-line resistor size; receiving one or more additional inputs relating to at least one of the power supply panel or the fire alarm system; and performing one or more calculations based on the first, second, and third inputs and the one or more additional inputs to generate outputs for determining compliant operation of the power supply panel integrated in the fire alarm system.

A method for selectively transmitting audio signals in a fire alarm system includes receiving, by a Notification Appliance Circuit (NAC) selecting device, an audio signal for transmission over a first NAC or a second NAC. Each of the first NAC and the second NAC includes respective groupings of one or more NAC appliances. The NAC selecting device receives a selection signal from a Fire Alarm Control Panel (FACP) electronically connected to the NAC selecting device. The selection signal identifies one or more NAC appliances that should be moved from a first grouping corresponding to the first NAC to a second grouping corresponding to the second NAC. The NAC selecting device selectively transmits the audio signal to one of the first NAC and the second NAC based on the selection signal.

A fire alarm control panel (FACP) in a fire alarm system includes a processor in communication with a communications interface. The processor is configured to receive an event signal from an initiation device. The FACP also includes a display, controlled by the processor, indicating a status of the fire alarm system and configured to present a plurality of icons corresponding to a plurality of voice messages to be selectively played in response to receiving one or more event signals from the initiation device. The FACP further includes an embedded microphone mounted in the fire alarm control panel adjacent to the display. The FACP also includes a programmable microphone interface controlled by the processor, in communication with the embedded microphone utilized in response to receiving one or more event signals from the initiation device.
