Best Access 9kw37-deu-15d-s3-626-rqe Electrified Cylindrical Lock

Product Description

The BEST ACCESS 9kw37-deu-15d-s3-626-rqe is an electrified cylindrical lock designed for commercial door hardware applications requiring electronic access control at the cylindrical lockset level. Operating on 24 volts DC with intermittent solenoid duty, this unit functions in a fail-secure, electrically unlocked (power-to-unlock) configuration. It features a flat lever with contour and angle return trim measuring 3.5 inches convex, paired with a 4.875-inch ANSI strike. The lock is prepared for Small Format Interchangeable Core (SFIC) cylinder installation but ships less cylinder. A licensed commercial door hardware technician or security integrator typically handles installation.

This electrified cylindrical lock is suited for storeroom-function applications in commercial and institutional facilities where controlled egress and electronic access management are required. The integrated Request to Exit (REX) switch supports access control panel integration, signaling door hardware status back to the system. The US26D satin chrome finish coordinates with standard commercial hardware schedules. ANSI Grade 1 construction meets heavy-duty commercial door hardware standards.

Key Features

• Fail-secure operation: lock remains secure when power is off; power to unlock
• 24 volts DC input with intermittent solenoid duty cycle
• Integrated REX (Request to Exit) switch for access control panel compatibility
• Prepared for SFIC cylinder, ships less cylinder for field keying flexibility
• Flat lever with contour and angle return, 3.5-inch convex trim
• 4.875-inch ANSI strike included; ANSI Grade 1 rated construction
• UL Listed; US26D satin chrome finish

Compatibility

Designed as an OEM-style electrified cylindrical lock replacement or new-install unit for commercial doors requiring storeroom function with 24 volt DC fail-secure operation and SFIC cylinder preparation.

Installation Notes

Installation should be performed by a licensed commercial door hardware technician or low-voltage access control integrator familiar with ANSI cylindrical lock prep and NEC low-voltage wiring requirements. Disconnect power to the access control panel and any associated power supply before wiring the solenoid leads. Verify door prep matches the 66 mm centerline-to-centerline throughbolt pattern before mounting. Do not apply continuous duty power to this solenoid; it is rated for intermittent duty only and continuous energization will damage the coil.
