Abstract
A device and method for self-testing fire detection devices that includes a smoke source housed within the fire detection device. The smoke source is typically a pressurized canister or cartridge, which stores or generates smoke or a smoke equivalent. In response to a signal from a controller, the smoke source releases the smoke or smoke equivalent in or near a sampling volume of the fire detection device to test the operation of the fire detection device. If the device is operating properly, it will be triggered in response to the smoke or a smoke equivalent.
Claims20
A fire detection device with a self-test capability, the device comprising:
- a smoke detection system for detecting smoke or smoke equivalent in a sampling volume;
- a smoke source for releasing smoke or smoke equivalent into or near the sampling volume;
- and
- a controller for determining whether the sampling volume is in communication with an ambient environment based on detection of the smoke or smoke equivalent by the smoke detection system.
A method for performing a self-test of a fire detection device, the method comprising:
- releasing smoke or a smoke equivalent into or near a sampling volume, the smoke or a smoke equivalent being stored in a smoke source that is housed within the fire detection device;
- detecting the smoke or smoke equivalent in the sampling volume;
- and
- determining whether the sampling volume is in communication with an ambient environment based on detection of the smoke or smoke equivalent.
