Abstract

An emergency lighting fixture is provided. The emergency lighting fixture includes a backup power supply. The backup power supply includes one or more batteries. The emergency lighting fixture includes one or more light sources. The emergency lighting fixture includes a transceiver. The emergency lighting fixture includes a controller configured to determine a status of the backup power supply. The controller is further configured to transmit a beacon signal via the transceiver. The beacon signal can include the status of the backup power supply.

First claim

What is claimed is:

1 . An emergency lighting fixture, comprising:
a backup power supply comprising one or more batteries; one or more light sources; one or more dual in-line package (DIP) switches; a transceiver; and a controller configured to perform operations, the operations comprising:
determining a status of the backup power supply; and
transmitting, a beacon signal via the transceiver, according to a wireless radio communications protocol, the beacon signal detectable by a receiver of a barcode scanner tuned to receive the beacon signal only when the barcode scanner is within a predetermined proximity of the emergency lighting fixture, the beacon signal comprising the status of the backup power supply,
wherein the barcode scanner is not a smart phone, tablet, or computer, and
wherein the beacon signal includes data including an identification code of the emergency lighting fixture, the identification code of the emergency lighting fixture having been generated by manipulation of the one or more DIP switches,
wherein the data also includes an identification code of a building in which the emergency lighting fixture is installed,
wherein the data indicates a location of the emergency lighting fixture within the building,
wherein the barcode scanner is configured to autonomously determine whether the one or more batteries require replacement based on the beacon signal and to generate a maintenance notification without requiring user interaction,
wherein the beacon signal is transmitted via the transceiver regardless of whether a terminal voltage of the one or more batteries is above or below a threshold voltage
wherein providing, by the barcode scanner, the maintenance notification to replace the one or more batteries includes first receiving approval from a user via a display screen of the barcode scanner, and
wherein providing the maintence notification to replace the one or more batteries comprises providing, in response to the approval, the maintence notification over a wireless network to a gateway device communicatively coupling the barcode scanner to a cloud computing device.

2 . The emergency lighting fixture of claim 1 , wherein determining a status of the backup power supply comprises:
monitoring a terminal voltage of the one or more batteries; and determining the status of the backup power supply based, at least in part, on the terminal voltage.

3 . The emergency lighting fixture of claim 2 , wherein transmitting the beacon signal occurs when the terminal voltage is less than a threshold voltage needed to power the one or more light sources during a power outage.

4 . The emergency lighting fixture of claim 2 , wherein transmitting the beacon signal occurs when the terminal voltage is greater than a threshold voltage needed to power the one or more light sources during a power outage.

5 . The emergency lighting fixture of claim 1 , wherein the data indicates a geographical location of the building in which the emergency lighting fixture is located.

6 . The emergency lighting fixture of claim 1 , wherein the data includes a date of manufacture for the emergency lighting fixture.

7 . The emergency lighting fixture of claim 1 , wherein the one or more light sources comprise one or more light emitting diode (LED) devices.

8 . The emergency lighting fixture of claim 1 , further comprising:
a plurality of indicator lights, each of the indicator lightings configured to emit light of a color indicative of a fault condition associated with the emergency lighting fixture.

9 . A method for generating a notification to replace one or more batteries of a backup power supply onboard an emergency lighting fixture, the method comprising:
transmitting, via a transceiver of the emergency lighting fixture according to a wireless radio communications protocol, a beacon signal regardless of whether a terminal voltage of the one or more batteries is above or below a threshold voltage; obtaining, at a receiver of a barcode scanner tuned to receive the beacon signal only when the barcode scanner is within a predetermined proximity of the emergency lighting fixture, the beacon signal transmitted by the emergency lighting fixture; and determining, by the barcode scanner, the one or more batteries need to be replaced based, at least in part, on the beacon signal; and responsive to determining the one or more batteries need to be replaced, providing without user interaction, by the barcode scanner, the notification to replace the one or more batteries, wherein the barcode scanner is not a smart phone, tablet, or computer, wherein the beacon signal includes data including an identification code of the emergency lighting fixture, the identification code being generated by the emergency lighting fixture based on a manipulation of one or more DIP switches of the emergency lighting fixture, wherein the data also includes an identification code of a building in which the emergency lighting fixture is installed, wherein the data indicates a location of the emergency lighting fixture within the building, wherein providing, by the barcode scanner, the notification to replace the one or more batteries includes first receiving approval from a user via a display screen of the barcode scanner, and wherein providing the notification to replace the one or more batteries comprises providing, in response to the approval, the notification over a wireless network to a gateway device communicatively coupling the barcode scanner to a cloud computing device.
