The Robotic Fire Watch System (RFW) is a rapidly deployable, portable, independent fire detection system that monitors flammable, explosive, and high‐value hazards in fire‐susceptible and post “hot work” areas. “Hot work” includes drilling, cutting, grinding, welding, soldering, burning, melting of flammable substances, and other spark‐producing activities. This system houses the NFPA 72-compliant alarm panel and video server in a water and fire-resistant enclosure. Subsequently, the device may be deployed to meet compliance standards during new building construction when fire detection systems have yet to be installed, or when fire protection systems are impaired or disabled.
