Fire Doors 7000
The Guardian™ Fire Door is engineered to meet ever-increasing demands of property owners and insurance underwriters in a simple, easy-to-test, and reset fire protection product. Utilizing standard chain hoist operation, these rolling steel doors feature a reliable, safe procedure for frequent drop testing with a U.L. label rated from 3/4-hour to 4-hour protection. Manual push-up operation, fail-safe, and automatic reset motor operation models are optional to the Guardian standard. The National Fire Protection Association (NFPA) and other model codes recommend frequent drop testing of rolling steel fire doors to ensure a continuous state of operational readiness. C.H.I. strongly promotes these recommendations with the Guardian’s advanced design features.
