10 Easy Steps on How to Install First Alert Smoke Alarm

Step 1: Choose the Right Location

The first step in installing your smoke alarm is choosing the right location for it. Keep in mind that smoke rises, so the alarm should be installed on the ceiling or high up on a wall. It is also essential to place it away from windows, doors, and vents that could interfere with its performance.

Choosing the Right Location

Step 2: Test the Alarm

Before proceeding with the installation, it’s crucial to test the First Alert Smoke Alarm to ensure it’s functioning properly. To do this, remove the alarm from its packaging and insert the batteries if it’s a battery-operated model. Locate the “test” button on the surface of the alarm – it’s usually prominently marked. Press and hold this button for a few seconds. You should hear a loud, piercing beep or siren that indicates the alarm is working correctly.

If you don’t hear anything, check to ensure the batteries are correctly installed, and try testing again. This step will need to occur after the wiring process is complete for hardwired models, which we’ll cover in a subsequent step. Testing the alarm before installation is a critical safety step, ensuring the device’s functionality when it’s most needed.

Step 3: Mark the Installation Spot

Once you’ve confirmed that the alarm functions properly, the next step is to pinpoint the exact location for installation. Use a pencil to lightly mark the spots on the ceiling or wall where the smoke alarm will be mounted. If you’re using a drill for a hardwired model, also mark where you’ll need to drill holes for the wiring.

It’s essential to measure the space accurately to ensure the alarm sits perfectly. For battery-operated models, this could be as simple as deciding the best position that covers the entire area effectively. In both cases, make sure the marked spot is at least 4 inches away from the wall/corner on the ceiling, or if on a wall, it is installed not more than 12 inches away from the ceiling to ensure optimal smoke detection.

Step 4: Install Mounting Bracket

After marking the location, the next step is to secure the mounting bracket that comes with your First Alert Smoke Alarm. Hold the bracket against the ceiling or wall where you marked the installation spots for both battery-operated and hardwired models. Using the screwdriver, screw the bracket into place.

Secure the Mounting Bracket

If you’re installing a hardwired model, ensure that the wiring can be routed through the center of the bracket. For those using sticky adhesive strips, instead of using screws, now is the time to adhere the bracket firmly to the surface following the manufacturer’s instructions. Ensure the bracket is secure, as it will hold your smoke alarm in place.

Step 5: Connect the Alarm (Hardwired Models Only)

This step involves connecting the alarm to your home’s electrical system for hardwired First Alert Smoke Alarms. Firstly, ensure that the power is turned off at the circuit breaker to avoid any electrical hazards. Next, thread the wires through the opening in the mounting bracket and connect them to the corresponding wires in the alarm—usually, this includes matching the black wires (hot), white wires (neutral), and any ground wires (green or bare).

Use wire nuts to secure the connections and ensure no loose strands are exposed. Tuck the connected wires neatly into the junction box. Once the wires are connected, carefully align the alarm with the mounting bracket and twist it to lock into place. It’s vital to guarantee a secure fit to prevent the alarm from dislodging.

Step 6: Attach the Alarm to the Bracket

After the wiring (for hardwired models) is securely connected and tucked away, or if you are installing a battery-operated model, the next step is attaching the smoke alarm to the mounting bracket. Gently place the alarm on the bracket.

For most models, you will need to align the notches on the alarm with the grooves on the bracket and turn the alarm clockwise until it clicks into place, indicating it is securely attached. Ensure the alarm is firmly fixed to prevent it from dislodging, yet easily accessible for maintenance such as battery replacement or cleaning.
