Exit Sign Wiring Diagram: A Comprehensive Guide

Exit signs are an essential safety feature in any building. They help guide people to safety in case of an emergency, such as a fire or power outage. However, many people are often confused about how to properly wire exit signs. In this article, we will provide a comprehensive guide on the exit sign wiring diagram, including the different types of exit signs, their wiring requirements, and more.

Types of Exit Signs

Before we dive into the wiring requirements, let’s first discuss the different types of exit signs:

1. Electrical Exit Signs

The most common type of exit sign is the electrical exit sign. These signs are powered by electricity and require a constant source of power to remain illuminated. They are typically hardwired into the electrical system of a building and require a connection to a backup power source, such as a generator or battery backup system, in case of a power outage.

2. Self-Illuminated Exit Signs

Self-illuminated exit signs are another type of exit sign. These signs are powered by a self-contained power source, such as a battery or photoluminescent material, and do not require an external power source. They are ideal for areas where electricity is not available or for use in areas where power outages are common.

3. Photoluminescent Exit Signs

Photoluminescent exit signs are a newer type of exit sign that are gaining popularity due to their energy efficiency and low maintenance requirements. These signs absorb ambient light and then release it in the form of a bright, highly visible glow, making the sign visible in low-light conditions.

Wiring Requirements for Exit Signs

The wiring requirements for exit signs vary depending on the type of sign being used. In general, electrical exit signs must be wired into the electrical system of the building and require a connection to a backup power source in case of a power outage. Self-illuminated exit signs and photoluminescent exit signs, on the other hand, do not require any external wiring and can be installed in any location.

1. Wiring Electrical Exit Signs

To wire an electrical exit sign, you will need to connect the sign to the building’s electrical system. This will require running electrical wiring to the location of the sign and connecting it to the appropriate circuit breaker. In addition, you will need to connect the sign to a backup power source, such as a generator or battery backup system, in case of a power outage.

It is important to note that electrical exit signs must be installed by a qualified electrician to ensure they are wired safely and in compliance with local building codes.

2. Installing Self-Illuminated Exit Signs

Self-illuminated exit signs do not require any external wiring and can be installed in any location. They are typically mounted to the wall using screws or adhesive tape and are powered by a self-contained power source, such as a battery or photoluminescent material.

3. Installing Photoluminescent Exit Signs

Photoluminescent exit signs are also easy to install and require no external wiring. They are typically mounted to the wall using screws or adhesive tape and rely on ambient light to remain illuminated. These signs are ideal for areas where electricity is not available or for use in areas where power outages are common.

Frequently Asked Questions

Here are some commonly asked questions about exit sign wiring:

Question Answer
Do all exit signs require wiring? No, self-illuminated and photoluminescent exit signs do not require external wiring.
Can I install an exit sign myself? While self-illuminated and photoluminescent exit signs are easy to install, electrical exit signs must be installed by a qualified electrician.
What type of backup power source is required for electrical exit signs? Electrical exit signs require a backup power source, such as a generator or battery backup system.
Can I wire multiple exit signs to the same circuit breaker? Yes, multiple exit signs can be wired to the same circuit breaker as long as the circuit is not overloaded.

Conclusion

Exit signs are an essential safety feature in any building, and it is important to ensure they are wired properly. By understanding the different types of exit signs and their wiring requirements, you can ensure your building is up to code and safe for occupants. Remember that electrical exit signs must be installed by a qualified electrician, and if you have questions or concerns about exit sign wiring, don’t hesitate to reach out to a professional.
