Exit signs with integrated emergency lights are critical safety features in commercial, industrial, and public buildings. These devices, often referred to as emergency exit sign combos, serve a dual purpose: they guide occupants to safety during normal conditions and provide illumination during power outages or emergencies. Proper installation ensures compliance with fire codes and building regulations while maximizing functionality. This guide outlines the step-by-step process for installing an exit sign with emergency lights, highlights key considerations, and provides tips to avoid common pitfalls.

Part 1: How to Install an Exit Sign with Emergency Lights

Installing an emergency exit sign combo requires careful planning, adherence to safety standards, and basic electrical knowledge. Below is a structured approach to ensure a successful installation:

Step 1: Select the Right Location

The placement of your exit sign with emergency lights is governed by local fire codes and the International Building Code (IBC). Key guidelines include:

Visibility: Install signs at eye level (typically 6–8 feet above the floor) and ensure they are unobstructed by doors, furniture, or decorations.

Pathway Coverage: Place signs above exit doors, along escape routes, and at intersections or turns. For large spaces, signs should be visible from a distance of at least 100 feet.

Emergency Lighting Range: Emergency lights must illuminate the path to the exit for a minimum of 90 minutes. Ensure the combo unit’s light coverage extends 20 feet along the escape route.

Step 2: Prepare the Mounting Surface

Wall or Ceiling Mount: Most exit sign combos are designed for wall or ceiling installation. Use a stud finder to locate secure mounting points.

Drill Holes: Mark the positions for screws or anchors based on the unit’s mounting template. Drill pilot holes to avoid damaging the surface.

Check for Obstructions: Ensure no wiring, pipes, or structural elements are behind the mounting area.

Step 3: Install the Backplate

The backplate is the base that holds the exit sign in place.

Align the backplate with the drilled holes and secure it using screws or anchors.

For ceiling installations, use a drop ceiling kit if applicable.

Step 4: Connect the Wiring

Exit sign combos typically require both AC power (for normal operation) and a battery backup (for emergencies).

Turn Off Power: Shut off the circuit breaker supplying power to the installation area.

Run Wiring: Connect the unit’s wires to the building’s electrical system:

AC Input: Link the black (hot) and white (neutral) wires to the corresponding circuit wires.

Ground Wire: Attach the green or bare copper wire to a grounding screw.

Battery Backup: The unit’s internal battery activates automatically during power failures. No additional wiring is needed for this feature.

Use Wire Nuts: Secure connections with UL-listed wire nuts and wrap them in electrical tape for safety.

Step 5: Attach the Exit Sign to the Backplate

Align the unit with the backplate and press firmly until it clicks into place.

Tighten any locking screws to prevent accidental dislodging.

Step 6: Test the Unit

Restore power and verify that the exit sign illuminates continuously.

Simulate a power outage by pressing the test button (usually located on the unit’s casing). The emergency lights should activate immediately.

Check the battery charge indicator to ensure the backup system is functional.

Part 2: Key Considerations When Installing an Exit Sign with Emergency Lights

To ensure safety and compliance, keep the following factors in mind:

1.Code Compliance

Local Regulations: Building codes vary by region. For example, the National Fire Protection Association (NFPA) 101 Life Safety Code specifies requirements for exit sign visibility, brightness, and placement.

UL Certification: Choose a unit with a Underwriters Laboratories (UL) 924 certification, which ensures it meets national safety standards.

2.Power Source

Dual Power: The unit must operate on AC power and switch to battery backup during outages. Avoid using extension cords or temporary wiring.

Battery Maintenance: Replace batteries every 2–3 years or as recommended by the manufacturer.

3.Environmental Factors

Temperature: Install the unit in areas where temperatures remain between 0°F and 122°F (-18°C to 50°C). Extreme cold or heat can damage batteries.

Moisture: Avoid damp locations unless the unit is rated for wet environments (e.g., IP65-rated fixtures).

4.Accessibility

Test Button: Ensure the test button is easily accessible for monthly functional checks.

Replacement Parts: Keep spare bulbs or batteries on hand for quick repairs.

Part 3: Conclusion

Installing an exit sign with emergency lights is a straightforward process when approached methodically. By selecting the right location, following wiring protocols, and prioritizing code compliance, you can create a safer environment for occupants. Remember that regular maintenance—such as monthly tests and battery replacements—is essential to ensure the unit functions during critical moments.

Emergency exit sign combos are not just regulatory requirements; they are lifesaving tools that demand respect and precision during installation. Whether upgrading an existing system or installing new units, always consult local fire codes and seek professional assistance if you’re unsure about electrical work. With proper setup, your exit sign with emergency lights will provide reliable guidance for years to come.

By adhering to the steps and considerations outlined in this guide, you can confidently install an emergency exit sign combo that enhances safety and meets all legal standards.
