Optional Locking Features

The optional locking features are designed to prevent unauthorized removal of the battery 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 • Standard flathead screwdriver.

Both locking features use locking pins, which are molded into the mounting bracket. Depending on which locking features you use, remove one or both pins from the mounting bracket using needle-nose pliers.

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

TO LOCK THE BATTERY COMPARTMENT

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

1.Install the battery so the terminals

on the battery match the terminals on the Smoke Alarm. Match “+” to “+” and “-” to “-.” Push the battery in until it snaps in securely and cannot be shaken loose. If the battery is not snapped in completely, the unit cannot receive battery power.

2. Push and hold Test/Silence button until the alarm sounds: 3 beeps, pause, 3 beeps, pause.

The Escape Light® will turn on. LED flashes once every second.

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

3. Using needle-nose pliers, detach one locking pin from the mounting bracket.

4. Push the locking pin through the hole near the battery door latch on the back of the Smoke Alarm.

TO UNLOCK THE BATTERY COMPARTMENT

1. Remove the Smoke Alarm

from the mounting bracket.

If the unit is locked to the

bracket, see the section

“To Unlock 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 compart- ment, close the battery door and reinsert locking pin in lock.

4. Reattach the Smoke Alarm to the mounting bracket.

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

TO LOCK THE MOUNTING BRACKET

1. Using needle-nose pliers, detach one locking pin from the mounting bracket.

2. Insert the locking pin through the hole on the back of the Smoke Alarm as shown in the diagram.

3. When you attach the Smoke Alarm to the mounting bracket, the locking pin’s head will fit into a notch on the bracket.

TO UNLOCK THE MOUNTING BRACKET

1. Insert a flathead screwdriver into the rectangular cut-out on the mounting bracket nearest to the locking pin.

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

SA720 specifications

The First Alert SA720 is a cutting-edge smoke and carbon monoxide detector designed to provide essential safety features for homes and businesses. Known for its reliable performance, this device integrates advanced technology to ensure early detection of smoke and harmful gases, which is crucial for protecting lives and properties.

One of the standout features of the SA720 is its dual-sensor technology. This dual-sensor system utilizes both photoelectric and ionization sensors, allowing for a broader range of smoke detection. Photoelectric sensors are highly effective at detecting smoldering fires, which produce larger smoke particles, while ionization sensors are more sensitive to flaming fires that generate smaller smoke particles. This combination significantly enhances the alarm's responsiveness, ensuring that it can react quickly to different types of fire scenarios.

Another important characteristic of the First Alert SA720 is its carbon monoxide detection capability. Carbon monoxide is a colorless, odorless gas that can be deadly in high concentrations. The SA720 detectors continuously monitor for this dangerous gas, providing an additional layer of safety for families. When carbon monoxide levels become hazardous, the device emits a loud alarm to alert occupants.

The SA720 is designed with user convenience in mind. It features a battery backup system, ensuring that the detector remains operational during power outages. The unit is powered by two AA batteries, making replacement straightforward and user-friendly. Moreover, the device includes an easy-to-read battery status indicator, which alerts users when it's time to replace the batteries, helping to keep the unit functional at all times.

Installation of the First Alert SA720 is a breeze, thanks to its lightweight design and mounting capabilities. It can be easily placed on walls or ceilings, adhering to the manufacturer's guidelines for optimal performance. The unit's sleek design also ensures that it blends seamlessly into various home decors, making it an aesthetically pleasing safety solution.

In conclusion, the First Alert SA720 smoke and carbon monoxide detector offers a robust combination of dual-sensor technology, ease of installation, and reliable detection of both smoke and harmful gases. Its user-friendly features make it a practical choice for those looking to enhance their safety measures at home or in the workplace. With the First Alert SA720, peace of mind is just a detector away.
