Dortronics 5211-MP23DA/R-E1, Exit Push Button, 1-9/16" Diameter Mushroom Button, with Form Z Pneumatic 2-60 Delay, Red Button, Stainless Steel Plate Engraved "PUSH TO EXIT"
- SKU:
- 5211-MP23DA/R-E1
This heavy-duty request-to-exit (REX) push button is designed for controlled and timed door release applications in modern access control systems. Featuring a large 1-9/16” red mushroom actuator, it provides high visibility and easy activation in emergency and egress situations.
Mounted on a durable single gang stainless steel wall plate, this unit integrates a DPST pneumatic time delay mechanism, allowing the door release signal to remain active for a preset duration after activation. This ensures safe, controlled exit timing—ideal for securing doors while still meeting life-safety requirements.
The engraved “PUSH TO EXIT” marking provides clear user instruction, making it suitable for commercial, institutional, and high-security environments.
