Enhanced?stress structure?design. The special?design of this lock is applied to all different brands of fire push rod lock. It is passed the 500,000 Mechanical test. You can set the operation mode of Fail Safe or Fail Secure.

YS-621-S(SS304) is suitable for fire exit door with Push-rod lock.The operating principle of electric strike is that electromagnetism produces the force to pull or push the release lever so that to lock or open the door.

YS-622N-S (SS304) This high-security electric strike (stainless steel) for double-door fire push-rod is designed for use with European and American standard fire push-rod locks. It offers both electronic control for normal operation and manual opening for emergencies. It features a set of door status signal outputs (NO, NC, and COM) to provide feedback to the access control system. This patented design integrates the internal moving parts, resulting in a robust structure and stable performance. It can be set to either (NO ‘Fail-Secure’ Power to Open) or (NC ‘Fail-Safe’Power to Lock) on-site. This model is constructed entirely of 304 stainless steel and has passed the EU 3-hour fire rating certification. When fire emergency exits require access control, this product transforms the one-way mechanical push-rod lock into a two-way access control system. It is the optimal solution for integrating emergency exits with access control systems in public facilities such as commercial hotels, office buildings, cinemas, airports, subways, factory buildings, and shopping malls.

YML-650A is our electromechanical lock,which is suitable for one-way open and two-way open doors,including wooden door,metal door,framed glass door etc.Stainless steel housing,unique design for safety requirement,switches to working mode by manual control.All linkages are metal structure.Work normally under the temperature between -40℃and 60℃.Pass 500000 times test.Outstanding performance,prior choice for project.
