Manual push-up, chain hoist and automatic reset motor operation is available for Guardian™ Fire Doors and can incorporate one of several release device options. The National Fire Protection Association (NFPA) and other model codes recommend frequent drop testing of rolling steel doors to ensure a continuous state of operational readiness. C.H.I. strongly promotes these recommendations with the Guardian's™ advanced design features.
