generate a prop notification indicative of an occurrence of a prop event of the door based on the door position status and the dogging status.

9. The exit device of claim 8 , further comprising a wireless communication circuitry, wherein the plurality of instructions further causes the exit device to wirelessly transmit the prop notification to a remote management system via the wireless communication circuitry.

10. The exit device of claim 8 , wherein the plurality of instructions further causes the exit device to determine the occurrence of the prop event in response to the door position status indicating the door is in the open position and the dogging status indicating the dogging mechanism is not positioned to hold the pushbar in the retracted position.

11. The exit device of claim 10 , wherein the determination of the occurrence of the prop event is in response to the door position status indicating the door is in the open position for at least a threshold amount of time.

12. The exit device of claim 8 , wherein the plurality of instructions further causes the exit device to:

determine a dogging schedule that identifies one or more times at which dogging of the exit device is permitted; and

determine the occurrence of the prop event in response to the dogging status indicating the dogging mechanism is positioned to hold the pushbar in the retracted position for at least a threshold amount of time outside of a permitted dogging time.

13. The exit device of claim 8 , wherein the plurality of instructions further causes the exit device to determine a latchbolt status of the exit device;

wherein the latchbolt status indicates whether a latchbolt of the exit device is in one of an extended position or a retracted position; and

wherein to generate the prop notification comprises to generate a prop notification based on the door position status, the dogging status, and the latchbolt status.

14. The exit device of claim 13 , wherein the plurality of instructions further causes the exit device to determine the occurrence of the prop event in response to the door position status indicating the door is in the closed position, the latchbolt status indicating the latchbolt is in the retracted position, and the dogging status indicating the dogging mechanism is not positioned to hold the pushbar in the retracted position.

15. The exit device of claim 8 , wherein the plurality of sensors comprises a door position sensor, a request-to-exit sensor, a latchbolt sensor, and a dogging status sensor.

16. The exit device of claim 15 , wherein the door position comprises a magnetometer.

17. A system for wireless door prop notification, the system comprising:

a management system; and

an exit device comprising a plurality of sensors adapted to generate sensor data, the exit device configured to (i) determine a door position status, a dogging status, and a latchbolt status of the exit device based on the sensor data, (ii) generate a prop notification indicative of an occurrence of a prop event of the door based on the door position status, the dogging status, and the latchbolt status and (iii) transmit the prop notification to the management system, wherein the door position status indicates whether a door is in one of a closed position or an open position, wherein the dogging status indicates whether a dogging mechanism of the exit device is positioned to hold a pushbar of the exit device in a retracted position, and wherein the latchbolt status indicates whether a latchbolt of the exit device is in one of an extended position or a retracted position.
