Krinkle Fire Door is a smart mobile app that guides inspectors to easily adhere to NFPA 80 standards, speed up work, and automate fire door/damper reporting. The system tracks customers, buildings, fire doors, fire door frames, and fire dampers, as well as all associated inspections. An additional module even tracks the repair process associated with defects found in the inspections, including parts and labor costing. Increase your company’s ROI (Return on Investment) by unburdening your inspectors from dealing with reports, thus increasing the volume of daily inspections they can perform. All inspection data and identifying information about buildings, doors, dampers, and inspection can be easily collected using an iPad or iPhone. Eliminate paper and streamline your workflow processes. Easily comply with regulations and maintain fully auditable records of all fire doors/fire dampers being up to code per industry standards (NFPA 80). Krinkle Fire Door is the perfect solution for inspection service companies, building owners and fire safety managers.
