Safety Considerations for Motorized Commercial and Industrial Doors:

When recommending safety accessories to your customers, it is important to assess the individual application. If door-to-floor protection is what they need, offer an electrically activated MC271 as part of the overall door safety system.

Model MC271 is designed for use on rolling steel doors accepting extruded bottom bars and are custom manufactured to the required length. Our sensing edges are designed to provide a safe means of stopping and/or reversing a door’s motion.

To install, slide the “T” into the accepting slot on the door’s bottom bar. When touch activated, the internal sensor sends a signal to the motor to stop and/or reverse motion.

Common installations for the MC271 can be found on rolling steel doors in warehouses and convention centers.

MC271 has been tested with most UL listed commercial operator manufacturers to comply with the UL 325-2010 standard and may be used as the required monitored device or as an ancillary device.

Safety Standards and Codes for Motorized Commercial and Industrial Doors:

Effective August 29, 2010, Underwriters Laboratories required that all commercial door operators bearing the UL label are required to be installed with a continuously monitored safety device.

Since 2009, the International Building Code (IBC-2009) has required compliance with the current UL 325 safety standard.
