Abstract
Devices, methods, and systems for performing multi-gas fire sensing device testing are described herein. One fire sensing device includes a self-test module and a controller configured to change a temperature within the self-test module, generate test media in response to the change in temperature; and detect a number of gases corresponding to the test media within the fire sensing device in response to changing the temperature within the self-test module.
Claims20
A fire sensing device, comprising:
- a self-test module;
- and
- a controller configured to:
- change a temperature within the self-test module;
- generate test media in response to the change in temperature;
- and
- detect a number of gases corresponding to the test media within the fire sensing device in response to changing the temperature within the self-test module.

A method, comprising:
- changing, by a controller of a fire sensing device, a temperature within a self-test module of the fire sensing device;
- generating test media in response to the change in temperature;
- detecting a number of gases corresponding to the test media within the fire sensing device in response to changing the temperature;
- and
- transmitting, by the controller, a result of the number of gases detected to be present within the fire sensing device to a remote computing device.
2 more elements
A system, comprising:
- a computing device;
- and
- a fire sensing device including:
- a multi-gas detector;
- and
- a controller configured to perform a self-test of the fire sensing device by:
- increasing a sensitivity of the multi-gas detector;
- detecting, via the multi-gas detector, a concentration of gases within the fire sensing device while the sensitivity of the multi-gas detector is increased;
- and
- transmitting the detected concentration of gases to the computing device;
- wherein the computing device is configured to determine whether the self-test was successful based on the detected concentration of gases determined to be present within the fire sensing device and additional gases determined not to be present within the fire sensing device while the sensitivity of the multi-gas detector is increased.
