Optional Locking Features

The locking features are designed to discourage unauthorized removal of the batteries or Alarm. It is not necessary to activate the locks in single-family households where unauthorized battery or Alarm removal is not a concern.

These Smoke Alarms have two separate locking features: one to lock the battery compartment, and the other to lock the Smoke Alarm to the mounting bracket. You can choose to use either feature independently, or use them both.

Tools you will need: • Needle-nose pliers or utility knife • Standard Flathead screwdriver.

Both locking features use locking pins, which are molded into the mounting bracket. Using needle-nose pliers or a utility knife, remove one or both pins from the mounting bracket, depending on how many locking features you want to use.

To permanently remove either lock, insert a flathead screwdriver between the locking pin and the lock, and pry the pin out of the lock.

Do not lock the battery compartment until you have installed the batteries and tested the alarm.

1.Push and hold Test button until the alarm sounds: 3 beeps, pause, 3 beeps, pause. LED flashes once every second.

If the unit does not alarm during testing, DO NOT lock the battery compartment! Install new batteries and test again. If the Smoke Alarm still does not alarm, replace it immediately.

2.Using needle-nose pliers or a utility knife, detach one locking pin from the mounting bracket.

2. Insert a flathead screwdriver under the head of the locking pin, and gently pry it out of the battery compartment lock. (If you plan to relock the battery compartment, save the locking pin.)

3. To relock the battery compartment, close the battery door and reinsert locking pin in lock.

4. Reattach the Smoke Alarm to the mounting bracket.

When replacing the batteries, always test the Smoke Alarm before relocking the battery compartment.

2. Pry the Smoke Alarm away from the bracket by turning both the screwdriver and the Smoke Alarm counterclockwise (left) at the same time.

SA320 specifications

The First Alert SA320 is a state-of-the-art smoke and carbon monoxide detector designed to enhance home safety through advanced technology and user-friendly features. Combining a smoke alarm with a carbon monoxide detector into one compact unit, the SA320 offers dual protection, ensuring that homeowners are alerted to two of the most common and deadly household hazards.

One of the standout features of the SA320 is its photoelectric smoke detection technology. Unlike traditional ionization smoke detectors, photoelectric technology is more effective at sensing smoldering fires, which produce larger smoke particles. This capability helps reduce false alarms often triggered by cooking or steam, providing peace of mind for everyday use.

In addition to smoke detection, the SA320 includes a built-in carbon monoxide detector that reliably monitors levels of this colorless, odorless gas. Carbon monoxide is often referred to as the "silent killer" because it can go undetected until it is too late. The SA320 is designed to alert users with a loud alarm when CO levels rise to dangerous levels, ensuring timely evacuation and response.

The device is equipped with a battery backup, which means it will continue to function during power outages, keeping homes protected at all times. The SA320 also features an easy-to-read LED indicator that provides visual confirmation of the unit's operational status.

Another notable characteristic of the First Alert SA320 is its simple installation process. The unit can be easily mounted on a wall or ceiling, and its compact design allows it to blend seamlessly into any room's decor. Furthermore, it has a test/silence button that allows users to easily check the unit's functionality or silence false alarms without removing the device from its place.

The First Alert SA320 is also designed with a durable housing that can withstand typical household conditions, ensuring that it remains reliable over time. The unit complies with the latest safety standards, providing users with confidence in its effectiveness and reliability.

In summary, the First Alert SA320 combines innovative smoke and carbon monoxide detection technologies with user-friendly features, making it an essential tool for enhancing home safety. Its reliable performance, easy installation, and dual hazard detection capabilities position it as an invaluable addition to any household, promoting a safer living environment for families.
