Exit signs are an essential part of any building, providing clear direction to the nearest exit in case of an emergency. Proper installation and wiring of exit signs ensure they are always visible and functioning correctly. In this article, we will discuss the wiring diagram for exit signs, including the different types of exit signs, how to install them, and frequently asked questions.
Types of Exit Signs
Before we dive into the wiring diagram, it’s important to understand the two types of exit signs available: electric and self-luminous.
Electric Exit Signs
Electric exit signs rely on an external power source to illuminate. They can be connected to the building’s electrical system or powered by a backup battery in case of a power outage. The wiring for an electric exit sign is slightly more complex than a self-luminous one, but it ensures the sign is always lit.
Self-luminous Exit Signs
Self-luminous exit signs require no external power source and are instead designed to glow in the dark. They are commonly used in areas where electrical wiring is not feasible, such as stairwells, and are usually more expensive than their electric counterparts. Self-luminous exit signs require no wiring, making them much easier to install.
How to Install Electric Exit Signs
Electric exit signs require wiring to ensure they are always illuminated. Follow these steps for proper installation:
Step 1: Turn off power
Before beginning any electrical work, always turn off power to the circuit you will be working on. Turning off power prevents injury and minimizes the risk of electrical shock.
Step 2: Mount the exit sign
Mount the exit sign in the desired location, ensuring it is visible from all angles. The sign should be mounted securely to prevent it from falling or shifting over time.
Step 3: Connect power supply
Next, connect the power supply to the exit sign. The power supply should be connected to a dedicated circuit with the appropriate voltage and amperage rating for the sign.
Step 4: Connect the exit sign
Connect the exit sign to the power supply, following the manufacturer’s instructions. Typically, the wiring will consist of a black wire for power and a white wire for ground.
Step 5: Test the sign
Once the wiring is complete, turn on the power and test the exit sign to ensure it is functioning correctly. If the sign does not illuminate, double-check the wiring and connections.
How to Install Self-Luminous Exit Signs
Self-luminous exit signs do not require wiring, making them much easier to install. Follow these steps for proper installation:
Step 1: Mount the exit sign
Mount the self-luminous exit sign in the desired location, ensuring it is visible from all angles. The sign should be mounted securely to prevent it from falling or shifting over time.
Step 2: Test the sign
Once the exit sign is mounted, test it to ensure it is functioning correctly. Self-luminous exit signs should glow in the dark without any additional wiring or power supply.
Frequently Asked Questions
| Question | Answer |
| Do exit signs require wiring? | Electric exit signs require wiring to ensure they are always illuminated. Self-luminous exit signs do not require wiring and instead rely on glowing in the dark. |
| What voltage is required for an electric exit sign? | The voltage required for an electric exit sign varies depending on the manufacturer and model of the sign. Refer to the manufacturer’s instructions for the appropriate voltage and amperage rating. |
| Can exit signs be mounted on a drop ceiling? | Yes, exit signs can be mounted on a drop ceiling. However, it’s important to ensure the sign is mounted securely to prevent it from falling or shifting over time. |
| Do self-luminous exit signs require maintenance? | Yes, self-luminous exit signs require some maintenance to ensure they are always glowing in the dark. Refer to the manufacturer’s instructions for specific maintenance requirements. |
| Can exit signs be lit with LED lights? | Yes, exit signs can be lit with LED lights, which are more energy-efficient than traditional incandescent bulbs. Check the manufacturer’s instructions for compatible LED lights. |
Conclusion
Proper installation and wiring of exit signs ensure they are always visible and functioning correctly, providing clear direction to the nearest exit in case of an emergency. Follow the manufacturer’s instructions for both electric and self-luminous exit signs and always turn off power before beginning any electrical work. With the right installation and maintenance, exit signs can last for many years, providing critical safety information for your building’s occupants.
