Ensuring Reliable Egress: The Importance of Exit Device Power Supply

Oct 16

Powering the Safety of Emergency Egress Systems


In the world of building safety, exit devices are critical components, enabling swift egress during emergencies. These devices rely on an exit device power supply to ensure they function reliably when needed most. In this article, we will explore the significance, types, and essential considerations of exit device power supplies in enhancing the safety of buildings.


The Vital Role of Exit Device Power Supply


Powering the Means of Egress


Exit devices, commonly known as panic bars or push bars, are designed to facilitate quick and secure exits during emergency situations. These devices are typically installed on doors in public and commercial buildings. To ensure their proper operation, a cylindrical electric strikes is required to provide consistent electrical power.


Types of Exit Device Power Supply


Hardwired Power Supplies


Hardwired exit device power supplies are directly connected to the building's electrical system. They are a reliable and constant source of power, ensuring that exit devices are always operational. Hardwired power supplies are commonly used in buildings where consistent power is crucial, such as hospitals, schools, and high-rise office buildings.


Battery Backup Power Supplies


Battery backup power supplies provide a secondary source of power to exit devices in the event of a primary power failure. They are essential for ensuring that exit devices continue to function during emergencies, even if the building's main power source is disrupted. Battery backup power supplies are commonly found in a wide range of buildings, including hotels, retail stores, and manufacturing facilities.


Solar-Powered Exit Devices


Solar-powered exit devices harness the energy from the sun to operate, making them an environmentally friendly and energy-efficient option. These devices are equipped with photovoltaic panels that convert solar energy into electrical power, which is stored in batteries for use during the night or in low-light conditions. Solar-powered exit devices are often used in eco-conscious buildings and locations with abundant sunlight.


Importance and Considerations


Reliability During Emergencies


The primary function of exit devices is to ensure the safe and swift evacuation of building occupants during emergencies. Therefore, the reliability of the panic exit devices is of utmost importance. A consistent power source, whether hardwired or battery backup, ensures that the exit devices will function as intended when needed most.


Compliance with Building Codes


Building codes and regulations often stipulate specific requirements for exit devices and their power supplies. Compliance with these codes is not only a legal requirement but also crucial for the safety of building occupants. Building owners and managers should ensure that their exit devices and power supplies meet all relevant standards and regulations.


Regular Maintenance and Testing


To ensure the continued reliability of exit devices and their power supplies, regular maintenance and testing are essential. Battery backup systems should be checked periodically to ensure that the batteries are functioning correctly and have sufficient charge. Hardwired systems should be inspected to identify any potential issues that could affect power delivery.




Commercial door hardwares are the unsung heroes of building safety, providing the electrical energy needed to ensure the reliable operation of exit devices during emergencies. Whether hardwired, battery backup, or solar-powered, these power supplies play a crucial role in safeguarding the lives of building occupants. Building owners and managers should prioritize the selection, installation, and maintenance of surface door closers to ensure that their emergency egress systems are always ready to perform their vital function. By doing so, they can enhance the overall safety and security of their buildings.
