What is a Push to Exit Button?
Push to exit buttons are an essential part of s4a access control applications. It is a spring-loaded, button which is often mounted on a stainless steel plate. The button comes in different styles. It can be a simple or large button, green, or button that illuminate LED lights. The exit push button is used to “request to exit” devices in the access control system that are used on doors, exits, gates, automation control, and so forth.

When Should a Push to Exit Button Be Installed?
One of the advantages of the push to exit button is the versatility it offers. Exit buttons are suitable for use in electronic locking solution which needs to provide a free exit option on the door. The exit push button can be used on fire doors, gates, or anywhere you can install an access control system. It can be used as exit devices in residential, commercial, and industrial buildings.

In some cases, the push to exit buttons can be used when the access control panel fails to unlock the door. It can be used when the door’s handle isn’t suitable, or the user is not able to use the handle physically. However, the button must be able to hold enough power for the door to open freely.

How Does the Exit Push Button Work?
The push to exit button is connected to the access control application, which controls the locking mechanism of the door, using wires. Any individual that needs to exit the building or pass through the door simply has to push or press the button.

When pushed, it momentarily releases the fail-secure or fail-safe lock of the door. The exit button releases power to the magnetic lock. With this, the door automatically releases and allows free exit. The lock will disengage, thus, opening the door as required.

Push to exit buttons mainly come in two types:
1. Regular wall-mount push to exit buttons

2. Motion sensors to trigger the door to unlock

There are also panic exit devices such as push to exit bars. Here is a quick video of how push to exit buttons work:

Either one of the push-to-exit or motions sensor can be used for securing doors that can't be unlocked with a regular lock or deadbolt. That means we are talking about locks which are locked permanently and you can only get out if you trigger the exit sensor or push to exit button. The biggest manufacturer is S4A who manufactures the access control push to exit buttons.

How to Choose the Right Push to Exit Button for Your Access Control System

Furthermore, it is important to choose the ideal exit push button for your access control system. However, the right exit button for your access control application will depend on your existing door locking system.

The available exit buttons include:

· N/C circuits – Normally Closed Circuit

· N/O circuits – Normally Open Circuit

· COM option

The N/C interrupts power flow when the exit button is pressed while the N/O allows power to flow when the button is pressed. The COM option can operate for both closed and open circuits. Ensure that you use the right push to exit button, which is compatible with your access control system.
