Abstract
Devices, methods, and systems for an event sensing device are described herein. One device includes a variable airflow device and a controller configured to activate the variable airflow device to increase airflow into the event sensing device responsive to the event sensing device or a neighboring event sensing device detecting an unconfirmed fire, detect whether a fire is occurring using the increased airflow responsive to activating the variable airflow device, and report a confirmed fire responsive to detecting a fire occurring.
Claims20
An event sensing device, comprising:
- a variable airflow device;
- and
- a controller configured to:
- activate the variable airflow device to increase airflow into the event sensing device responsive to a neighboring event sensing device detecting an unconfirmed fire;
- detect whether a fire is occurring using the increased airflow responsive to activating the variable airflow device;
- and
- report a confirmed fire responsive to detecting the fire is occurring.
A method of operating an event system, comprising:
- receiving, by an event detection system, a report of an unconfirmed fire from a first event sensing device;
- transmitting a command from the event detection system to a second event sensing device to activate a variable airflow device of the second event sensing device responsive to receiving the report of the unconfirmed fire, wherein the second event sensing device is a neighboring event sensing device of the first event sensing device;
- and
- indicating the second event sensing device is active on a display of the event detection system responsive to transmitting the command to the second event sensing device.
A system, comprising:
- a first event sensing device configured to:
- measure a quantity of particles in an optical scatter chamber of the first event sensing device;
- and
- transmit a report of an unconfirmed fire based on the quantity of particles;
- and
- an event detection system configured to:
- receive the report of the unconfirmed fire;
- transmit a command to the first event sensing device to activate a variable airflow device of the first event sensing device responsive to receiving the report of the unconfirmed fire;
- and
- transmit a command to a second event sensing device to activate a variable airflow device of the second event sensing device responsive to receiving the report of the unconfirmed fire, wherein the second event sensing device is a neighboring event sensing device of the first event sensing device.
