Emergencies, like accidents, fires, and other natural disasters, can strike at any moment, often catching you off guard and leaving little time to react. Such situations require a swift and safe evacuation method to ensure everyone gets out timely, minimizing loss. This is where push-to-exit buttons come into play—a seemingly unassuming device that holds within it a multitude of benefits. 

They make it simple to exit buildings, help people with disabilities, and prevent panic in emergencies. In case you want to know more about a push-to-exit button along with its working, types, and the best options to try, let’s dive in!

What is a Push to Exit Button?

A push-to-exit button (PTE) is a device typically installed near an exit door or gate in buildings and facilities. When pressed, it temporarily unlocks or releases the door, allowing you to exit quickly during emergencies or even normal use. 

PTEs play a pivotal role in emergency egress systems, promoting swift evacuation in fires, natural disasters, or security threats. The cherry on the cake – PTEs or door release buttons are easily accessible and user-friendly, making them inclusive for people of all abilities. 

Components of a Push-to-Exit Button

Here are the components of a push-to-exit button:

Button or Actuator

The button or actuator is the most visible part of the PTE button. It is a physical interface that you can press to activate the device.

Switch

The switch is the electrical part of the push-to-exit (PTE) system that comes into play when you press the button. It has a spring-loaded mechanism that either opens or closes an electrical circuit upon pressing the button. 

Electrical Wiring

Push-to-exit buttons are connected to the building’s electrical system. Electrical wires run from the button to the control panel or the door’s locking mechanism. They carry the electrical signal needed to unlock the door when the button is pressed.

Housing

A backbox or housing may be used to house and protect the wiring and electrical connections behind the wall or surface where the button is mounted. The material of the housing is usually high-quality plastic. 

Indicator Lights (Optional)

In some cases, push-to-exit buttons may include indicator lights to provide visual feedback. It may confirm that the button press has been registered or indicate the door is unlocked.

How Does a Push to Exit (PTE) Button Work? 

The push-to-exit (PTE) button operates as a critical component of an emergency egress system, facilitating individuals’ safe and rapid exit from a building or secured area. All you’ve to do is simply press the PTE button to exit the building. The push-to-exit button has a spring-loaded switch mechanism. 

Pressing the button momentarily interrupts the electrical circuit, which is connected to the door’s locking or access control system. This interruption signals the system to release the door lock, allowing it to swing open or disengage its latch mechanism.

How to Install a Push-to-Exit Button? 

Some of the steps you must follow to install a PTE button are:

Step 1: Determine the Location

Identify the ideal location for the PTE button. It should be easily accessible and within the reach of all building occupants, including those with disabilities. Common locations include near exit doors, adjacent to access control systems, or along escape routes.

Step 2: Power Supply

Ensure that there is a nearby power source for the PTE button. Why? The button needs an electrical connection to function correctly. If necessary, hire an electrician to provide power to the installation location.

Step 3: Prepare the Mounting Surface

If you mount the PTE button on a wall, door frame, or other surfaces, ensure it is clean and smooth. Ensure there is sufficient space for the button and its enclosure.

Step 4: Mounting Bracket or Backbox

Depending on the design of the PTE button, you may need to install a mounting bracket or back box. This provides a secure and stable platform for the button. Secure the bracket or backbox to the chosen location using appropriate hardware, such as screws or anchors.

Step 5: Wire Connections

Connect the push button electrical wiring to the building’s electrical system. Follow the manufacturer’s instructions and any applicable local electrical codes. Typically, you will have wires for power (usually 12V or 24V DC), common, and relay or signal connections.

Step 6: Test the Functionality

After wiring, test the PTE button to ensure it operates correctly. Press the button to confirm that it releases the door or activates the egress system as intended.

Types of Push-to-Exit Buttons

Here are the types of push-to-exit buttons you should know:

Based on Design 

Following are the types of PTE buttons depending upon designs:

Surface-Mounted Push to Exit Button

Surface-mounted PTE buttons are affixed directly to the surface of a wall, door frame, or other flat surfaces. They are the most common and straightforward type, providing a physical button that users press to trigger the exit mechanism. They are also easily recognizable and ideal for most standard applications due to their ease of installation and accessibility.

Wireless Push-to-Exit Button

Wireless PTE buttons are designed to eliminate the need for physical wiring connections between the button and the control system. They communicate wirelessly, often using radio frequency (RF) technology, to signal the door release or egress system. This type offers installation flexibility and is particularly useful in retrofitting or situations where wired connections are challenging to implement.

Touchless Infrared Push-to-Exit Button

Touchless PTE buttons incorporate infrared sensor technology to detect the presence or motion of a user’s hand or body without physical contact. 

When you approach the sensor within a specified range, it activates the exit mechanism, making it a hygienic and hands-free option. They are preferred in settings where minimizing contact is essential, such as healthcare facilities, restaurants, and cleanroom environments.

Based on Locks 

The types of PTE buttons depending upon locks are:

Fail-Safe PTE Button

Fail-safe buttons have locks that are normally locked as long as there’s a power outage and will release the lock when the button is pressed (power supplied), allowing the door to open. It is often used in high-security environments to maintain locking mechanisms, even during power failures or emergencies.

Fail-Secure PTE Button

The fail-secure PTE button has locks that are normally unlocked without power but will lock when power is applied. When the button is pressed, it supplies power to the lock momentarily, securing the door. They are used in situations prioritizing safety and ease of egress, like fire exits, ensuring that doors stay locked during normal operation but open easily during emergencies or power outages.

Benefits of Push-to-Exit Buttons

Here are a few benefits of PTE buttons:

Swift Egress

PTE buttons provide a quick and convenient way for you to exit a building or secured area during emergencies. With a simple button press, you can initiate the release of doors, gates, or locks, allowing for your rapid evacuation.
