WEEKLY TESTING

•NEVER use an open flame of any kind to test this unit. You might accidentally damage or set fire to the unit or to your home. The built- in test switch accurately tests the unit’s operation as required by Underwriters Laboratories, Inc. (UL).

•If the Alarm ever fails to test properly, replace it immediately. Products under warranty may be returned to the manufacturer for replacement. See “Limited Warranty” at the end of this manual.

DO NOT stand close to the Alarm when the horn is sounding. Exposure at close range may be harmful to your hearing. When testing, step away when horn starts sounding.

It is important to test this unit every week to make sure it is working properly. Using the test button is the recommended way to test this Smoke Alarm.

Press and hold the Test/Silence button on the cover of the unit until the alarm sounds (the unit may continue to alarm for a few seconds after you release the button). If it does not alarm, make sure the unit is receiving power and test it again. If it still does not alarm, replace it immediately.

During testing, you will hear a loud, repeating horn pattern: 3 beeps, pause, 3 beeps, pause. LED flashes once every second.

When testing a series of interconnected units you must test each unit individually. Make sure all units alarm when each one is tested.

REGULAR MAINTENANCE

Use only the replacement batteries listed below. The unit may not operate properly with other batteries. Never use rechargeable batteries since they may not provide a constant charge.

This unit has been designed to be as maintenance-free as possible, but there are a few simple things you must do to keep it working properly:

•Test it at least once a week.

•Clean the Smoke Alarm at least once a month; gently vacuum the outside of the Smoke Alarm using your household vacuum’s soft brush attachment. Test the Smoke Alarm. Never use water, cleaners or solvents since they may damage the unit.

•If the Smoke Alarm becomes contaminated by excessive dirt, dust and/or grime, and cannot be cleaned to avoid unwanted alarms, replace the unit immediately.

•Relocate the unit if it sounds frequent unwanted alarms. See “Locations To Avoid For Smoke Alarms” for details.

•When the batteries become weak, the Smoke Alarm will “chirp” about once a minute (the low battery warning). This warning should last 7 days, but you should replace the batteries immediately to continue your protection.

Choosing a replacement battery:

Your Smoke/CO Alarm requires two “AA” Energizer E91 batteries.

These batteries are available at many local retail stores.

Actual battery service life depends on the Alarm and the environment in which it is installed. All the batteries specified above are acceptable replacement batteries for this unit. Regardless of the manufacturer’s suggested battery life, you MUST replace the battery immediately once the unit starts “chirping” (the “low battery warning”).

To replace the batteries (without removing Alarm from the ceiling or wall):

1.Open the battery compartment.

2.Press tabs A and B as shown in the diagram

and remove each battery.

3. Insert the new batteries, making sure

 

they snap completely into the battery

AB

compartment. Match the terminals on the

ends of the batteries with the terminals on

 

the unit.

 

4. Close the battery compartment, and then test the unit by pressing the Test/Silence button.

IF THIS SMOKE ALARM SOUNDS

RESPONDING TO AN ALARM

During an alarm, you will hear a loud, repeating horn pattern: 3 beeps, pause, 3 beeps, pause.

•If the unit alarms and you are not testing the unit, it is warning you of a potentially dangerous situation that requires your immediate attention. NEVER ignore any alarm. Ignoring the alarm may result in injury or death.

•Never remove the batteries to quiet an unwanted alarm. Removing the batteries disables the Alarm so it cannot sense smoke. This will remove your protection. Instead, open a window or fan the smoke away from the unit. The Alarm will reset automatically.

•If the unit alarms get everyone out of the house immediately.

If the unit alarms and you are certain that the source of smoke is not a fire— cooking smoke or an extremely dusty furnace, for example—open a nearby window or door and fan the smoke away from the unit (Use the Silence Feature to silence the Alarm). This will silence the alarm, and once the smoke clears the unit will reset itself automatically.

WHAT TO DO IN CASE OF FIRE

•Don’t panic; stay calm. Follow your family escape plan.

•Get out of the house as quickly as possible. Don’t stop to get dressed or collect anything.

•Feel doors with the back of your hand before opening them.

If a door is cool, open it slowly. Don’t open a hot door. Keep doors and windows closed, unless you must escape through them.

•Cover your nose and mouth with a cloth (preferably damp). Take short, shallow breaths.

•Meet at your planned meeting place outside your home, and do a head count to make sure everybody got out safely.

•Call the Fire Department as soon as possible from outside. Give your address, then your name.

•Never go back inside a burning building for any reason.

•Contact your Fire Department for ideas on making your home safer.

Alarms have various limitations. See "Limitations of Smoke Alarms" for details.

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.
