Magnasphere Corporation announced a number of their UL-634 listed door contacts have been tested and are classified UL-10C, the standard for positive pressure tests of door assemblies. This allows Magnasphere contacts to be used in fire-rated doors.
“This is significant in high security door protection”, said Rick Kirschman, President of Magnasphere. “Our L2C-A-FIRE is the only recessed UL-634 level 2 listed door contact with a three-hour fire classification."
In addition to the L2C-A-FIRE, Magnasphere’s surface-mounted HSS-L2D and HSS-L2S Level 2 contacts received 20-minute fire classification, The Level 1 listed HS-L1.5 has a 45-minute fire classification and the MSS-300-FIRE, the company's multiple switch series, has received a three-hour classification.
Kirschman added, “Our MSS 300 series allows for one, surface or recessed contact, to trigger up to three systems in a fire rated door. This flexibility will enhance the system integration in any facility with fire rated doors."
