An apparatus is provided for providing simulated smoke. The apparatus comprises a reservoir including a reservoir port, and a bladder disposed in the reservoir. The bladder can be deflated to cause a fluid substance to flow through the reservoir port into the reservoir to fill the reservoir with the fluid substance to generate smoke. The bladder can be inflated to cause smoke to flow out of the reservoir through the reservoir port to provide simulated smoke.

Methods, devices, and systems for an unmanned system (US) for smoke detector testing are described herein. In some examples, one or more embodiments include a test kit, a processor, and a memory having instructions stored thereon which, when executed by the processor, cause the processor to perform a test procedure on a projected beam smoke detector in a facility using the test kit and communicate a result of the test procedure to a smoke detector network associated with the facility.
