ZPB-P21 Biometrics Attendance System Accessory

Q1. What is the Zahabi ZPB‑P21 push button used for?

ZPB‑P21 is a manual “Push to Exit” button used with biometric attendance and access control systems to release an electric lock and allow people to exit safely. It is typically mounted near the door on the secure side and sends a momentary signal to unlock the door when pressed.

Q2. Can the ZPB‑P21 work with my existing biometric or access controller?

Yes, ZPB‑P21 is designed to connect to standard access control panels, door controllers, and biometric terminals that accept a NO/NC exit input. It can momentarily activate or deactivate most fail‑safe or fail‑secure electric locks used in attendance and access systems.

Q3. Where is the ZPB‑P21 typically installed?

The ZPB‑P21 is usually installed inside the secure area, close to the door frame at a convenient hand height. Staff press it when they wish to exit, and the signal triggers the controller or lock to release the door for a short time.

Q4. Is ZPB‑P21 suitable for doors that must always allow free exit?

Yes, a Push to Exit button like ZPB‑P21 is commonly used on doors that must always allow safe egress, even when entry is controlled by biometrics or card access. It provides a clear, simple way to exit while keeping access managed from the outside.

Q5. What type of locks can ZPB‑P21 work with?

ZPB‑P21 can be wired to control fail‑safe or fail‑secure electric locks, strikes, and magnetic locks via the access controller or relay. As long as the access system supports a push‑to‑exit input, the button can be integrated.

Q6. Is ZPB‑P21 suitable for offices, schools, and commercial buildings?

Yes, push‑button exit devices are commonly used in offices, schools, clinics, and commercial buildings as part of access control systems. ZPB‑P21 is a practical, low‑cost accessory that fits well with Zahabi’s biometric attendance solutions.
