U.S. Smoke & Fire Fire Protective Smoke Curtains ESC Magnetic Seal Curtain
The ESC Magnetic Seal curtain is designed to protect elevator openings and shafts from smoke ingress and migration. The ESC Magnetic Seal curtain will deploy in the event of a signal from a local smoke detector, from a signal from the fire alarm system or on total power loss to the unit. The system will also supply its own battery backup power for 5 hours if batteries (optional) are connected in the integrated, concealed control unit. On signal or power loss the integrated UL864 approved releasing device will release the curtain roller and the fabric will safely descend under gravity attaching to the ferritic elevator frame or optional auxiliary rails via integrated magnets and making an approved smoke seal per UL1784.
