Marks USA EA195FEU Electric Storeroom Clutched Lever Lockset — Fail-Secure, Electric Unlock, Request to Exit

The Marks USA EA195FEU is a commercial-grade cylindrical electric storeroom clutched lever lockset engineered for demanding access control applications. Operating in the FEU (Electrically Unlocked / Fail-Secure) function, the outside lever remains locked until unlocked by key or electrical energization, while the inside lever always latches freely. Designed for 12VDC or 24VDC operation (24VDC standard, bridge rectifier supplied), this lockset features a 100% duty cycle, low operating current of 265 mA at 12VDC or 150 mA at 24VDC, and meets or exceeds ANSI/BHMA A156.13 Grade 1 standards. Compatible with door thicknesses of 1-5/8" to 1-7/8" and a standard 2-3/4" backset (optional 2-3/8", 3-3/4", or 5" available), the EA195FEU delivers a clean, secure installation ideal for stairwell doors, enterprise access control, and man-trap configurations.

Key Features

• Fail-Secure Electric Unlock (FEU) Function: Outside lever remains locked until unlocked by key or electrical energization; latch operated by inside lever at all times — ideal for stairwell doors with fire alarm system integration.
• Flexible Voltage Compatibility: Operates on 12VDC or 24VDC (24VDC standard); supplied with bridge rectifier for use with either AC or DC current, providing broad system compatibility.
• Low Operating Current: Draws only 265 mA at 12VDC or 150 mA at 24VDC for cool running and energy-efficient performance in continuous-duty installations.
• 100% Duty Cycle: Rated at 100% duty cycle, 3 watts, ensuring reliable continuous operation without overheating in high-demand access control environments.
• Request to Exit (REX) Switch: Single pole, double throw, 3 amp, 125 VAC switch wired either normally open or normally closed for seamless integration with enterprise access control and man-trap systems.
• Backset & Door Compatibility: Standard 2-3/4" backset with optional 2-3/8", 3-3/4", or 5" configurations; fits door thicknesses of 1-5/8" to 1-7/8" (use K1704 spacer for 1-3/8" doors).
• Latch & Strike Specifications: Latch #1834 with 1-1/8" x 2-1/4" front, 9/16" throw, and stainless steel nose; Strike #1135, 4-7/8" ASA curved lip for secure latching.
• Solid Cast Zamac Levers: American lever design in solid cast Zamac with 1/2" return; thru-bolted rose at 3-7/16" diameter with spring-loaded 2-#10 thru-bolts for robust, tamper-resistant mounting.
• Marks C Keyway Cylinder: MARKS "C" keyway, 6-pin cylinder supplied with 2 keys for reliable keyed access control.
• Labor-Saving Installation: Wiring directly through hinges eliminates the need to cut into cement-filled frames, offering significant time and labor savings over electric strike installations with a cleaner finished appearance.
• Concealed Latch for Enhanced Security: Electrified cylindrical design conceals the latch keeper, providing greater security than electric strikes with exposed latch keepers.
• Stainless Steel Retractor: Long-life stainless steel retractor in the cylindrical model ensures extended service life in high-traffic commercial applications.
