Marks USA 195FEU Electrically Unlocked Lever Lockset — Grade 1 Survivor Series, Fail-Secure, 6-Million-Cycle Rated

The Marks USA 195FEU is a Grade 1 Survivor Series electrically unlocked cylindrical lever lockset engineered for demanding commercial applications. Featuring fail-secure electric unlock operation at 24V/AC with bridge rectifier (24V/DC, 0.21 Amps), this lockset is life-tested over 6 million cycles and withstands torque of 1,800 inch-pounds — over twice the ANSI/BHMA (1996) test value. Designed for door thicknesses of 1-5/8" to 1-7/8" (K1704 spacer required for 1-3/8" doors), it ships with a 2-3/4" standard backset and is UL Listed with a 3-hour fire rating.

Key Features

• Exceptional Torque Resistance: Withstands 1,800 inch-pounds of torque — more than twice the ANSI/BHMA (1996) test value — for superior durability under abuse.
• 6-Million-Cycle Life Rating: Life-tested over 6 million cycles and fully operational after testing, ensuring long-term reliability in high-traffic commercial environments.
• Fail-Secure Electric Unlock Operation: 100% duty cycle electrified function at 24V/AC with bridge rectifier; 24V/DC at 0.21 Amps standard, with 12V/DC optional for flexible system integration.
• Breakaway Lever Design: American and Crescent design breakaway handles protect against excessive abuse, reducing torque applied to the outside lever and preventing premature failure.
• The Clutch Technology: Patented clutch disengages the outside lever when locked, allowing it to turn freely without opening the latch — eliminating the rigid-lever failure mode common in other locksets.
• Precise Dimensional Specifications: Standard 2-3/4" backset (2-3/8", 3-3/4", and 5" optional); Latch #1834 with 1-1/8" x 2-1/4" front and 9/16" throw; stainless steel nose; Rose: 3-7/16" diameter thru-bolted with 2 #10 thru-bolts; Strike #1135, 4-7/8" ASA curved lip.
• Heavy-Duty Construction: Cast stainless steel retractor with bronze roller bearings; solid cast Zamac levers with 1/2" return; #10 epoxy-coated thru-bolts for vibration-proof mounting.
• Request-to-Exit Switch: Single pole, double throw, 3 amp, 125 VAC — wired normally open or normally closed (REX Switch not standard on electrified leverset).
• Versatile Cylinder Options: Supplied with Marks "C" keyway 6-pin cylinders and 2 nickel-silver keys, or IC Core housing available.
• ADA Compliant: Lever design meets ADA accessibility requirements for commercial door hardware applications.
