Abstract
An exit device according to one embodiment includes a plurality of sensors and an electronic dogging mechanism. The exit device is configured to locally analyze sensor data to determine the security state of the exit device, report data to a management system via a wireless communication channel established between the exit device and the management system, and receive and process instructions to perform an electronic dogging operation.
Claims20
A method, comprising:
- determining, by an exit device secured to a door, a door position status and a dogging status of the exit device based on a plurality of sensors of the exit device, wherein the door position status indicates whether the door is in one of a closed position or an open position, and 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;
- generating, by the exit device, a prop notification indicative of an occurrence of a prop event of the door based on the door position status and the dogging status;
- and
- transmitting, by the exit device, the prop notification to a remote management system.
1 more element
An exit device, comprising:
- a plurality of sensors adapted to generate sensor data;
- a pushbar;
- a processor;
- and
- a memory comprising a plurality of instructions stored thereon that, in response to execution by the processor, causes the exit device to:
- determine a door position status and a dogging status of the exit device based on the sensor data, wherein the door position status indicates whether a door is in one of a closed position or an open position, and wherein the dogging status indicates whether a dogging mechanism of the exit device is positioned to hold the pushbar of the exit device in a retracted position;
- and
- 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.
5 more elements
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.
