YALE YB17-12 NC Electric Strike Fail-Secure 8-16V AC/DC Mechanical Override Universal 20mm

Product Overview

YALE YB17-12 NC is a universal fail-secure electric strike suitable for left- or right-hand doors, designed for use in professional access control systems in office, commercial, and residential buildings. With a symmetrical housing allowing for both vertical and horizontal installation, it operates on a wide input voltage range of 8-16 V AC/DC and is compatible with standard mortise locks. The YB17-12 is not intended for fire-rated doors and works reliably in environments from -15°C to +40°C.

A key differentiator of this model is its integrated mechanical switch, which provides manual override to keep the strike unlocked during working hours or emergencies, eliminating the risk of locked access during power failure or system maintenance. This feature simplifies project planning for installers and facility managers seeking redundancy in access control points and is recommended for B2B buyers specifying hardware for multi-tenant or high-traffic buildings.
