Installation Instructions for the 9120B
Before commencing the installation of your First Alert 9120B alarm‚ prioritize safety․ ELECTRICAL SHOCK HAZARD⁚ Turn off the power at the circuit breaker to the area where you plan to install the alarm․ Failure to do so may result in serious injury or death․ Ensure the mounting location is suitable – ideally on a ceiling or high on a wall‚ at least 4 inches from where the wall and ceiling meet․ Avoid areas near kitchens or bathrooms where steam or cooking fumes could trigger false alarms․
Remove the mounting bracket from the back of the alarm by twisting it counterclockwise․ Position the bracket on the chosen surface and mark the screw locations․ Drill pilot holes if necessary‚ then secure the bracket using the provided screws․ Connect the alarm wires to your home’s wiring‚ matching the colors carefully (black to black‚ white to white‚ and red to the red wire from the alarm)․ Secure the wire connections with wire connectors․
Attach the alarm to the mounting bracket by aligning it and twisting clockwise until it locks into place․ Install a new 9-volt battery into the battery compartment․ Restore power at the circuit breaker and test the alarm by pressing the test button․ The alarm should sound a loud‚ consistent beep․ If it does not‚ double-check the wiring and battery connections․ Repeat the testing procedure monthly to ensure proper functionality․
Understanding the Alarm Signals
The First Alert 9120B utilizes distinct alarm signals to communicate different types of emergencies‚ enabling you to respond appropriately and promptly․ A crucial aspect of owning this device is understanding these signals to ensure your family’s safety․ A continuous‚ loud‚ repeating pattern of three beeps indicates the presence of smoke or fire․ This requires immediate action‚ such as evacuating the premises and contacting emergency services․
In contrast‚ a pattern of four beeps signals the detection of carbon monoxide (CO)․ CO is an odorless‚ colorless gas‚ making it particularly dangerous․ Upon hearing this signal‚ immediately move to fresh air‚ and then call emergency services or a qualified professional to investigate the source of the CO․ A single chirp sound‚ usually occurring every minute‚ typically signifies a low battery․ Replace the battery immediately when you hear this chirp to ensure the alarm’s continued functionality during an actual emergency․
The test button‚ when pressed‚ should trigger a loud‚ consistent alarm sound‚ confirming that the alarm’s circuitry and siren are working correctly․ Regularly test your alarm to ensure it’s functioning correctly․ Familiarize yourself with these distinct signals to react swiftly and effectively during an emergency․
Testing and Maintenance Procedures
Regular testing and maintenance are vital for ensuring the First Alert 9120B functions correctly and provides reliable protection․ Testing the alarm weekly is highly recommended․ To test‚ simply press and hold the test button on the alarm’s cover until the alarm sounds․ The alarm should emit a loud‚ consistent beep‚ indicating that the sensor‚ electronics‚ and horn are functioning properly․ If the alarm fails to sound‚ check the battery and ensure it is correctly installed․ If the alarm still doesn’t sound after replacing the battery‚ replace the entire unit․
Dust and debris can accumulate on the alarm sensor‚ affecting its sensitivity․ Clean the alarm at least once every six months․ Use a vacuum cleaner with a soft brush attachment to gently remove dust from the exterior of the alarm․ Avoid using water‚ detergents‚ or solvents to clean the alarm‚ as these can damage the sensor and electronics․ Never paint the alarm‚ as paint can block the sensor openings and prevent it from detecting smoke or carbon monoxide․
Keep the alarm free from obstructions․ Do not place anything near the alarm that could block airflow to the sensor․ Replace the battery at least once a year‚ or immediately when the low battery warning sounds․ Following these simple testing and maintenance procedures will help ensure the First Alert 9120B provides continuous and reliable protection for your home and family․
Battery Replacement Guide
The First Alert 9120B utilizes a 9-volt battery as a backup power source‚ ensuring continuous operation during power outages․ Regular battery replacement is crucial for maintaining the alarm’s reliability․ When the alarm begins to chirp intermittently‚ it indicates a low battery and requires immediate replacement․ It’s recommended to replace the battery at least once a year‚ even if the low battery warning hasn’t sounded․ A good practice is to replace the battery when you change your clocks for daylight saving time․
To replace the battery‚ first‚ gently twist the alarm counterclockwise to detach it from the mounting bracket․ Locate the battery compartment on the back of the alarm; Open the battery compartment and remove the old battery․ Properly dispose of the old battery according to local regulations․ Insert a new 9-volt battery into the battery compartment‚ ensuring correct polarity (+ and -)․ Close the battery compartment securely․
Reattach the alarm to the mounting bracket by twisting it clockwise until it locks into place․ Test the alarm by pressing and holding the test button until the alarm sounds․ A loud‚ consistent beep indicates that the new battery is functioning correctly․ If the alarm doesn’t sound‚ double-check the battery installation and ensure that the battery is fresh․ If the alarm still fails to sound after replacing the battery‚ the unit may need to be replaced․
Troubleshooting Common Issues
The First Alert 9120B is generally reliable‚ but occasional issues may arise․ One common problem is nuisance alarms‚ which can be triggered by steam from showers‚ cooking fumes‚ or excessive dust; Ensure proper ventilation in these areas․ Try relocating the alarm if nuisance alarms persist․ A persistent chirping sound usually indicates a low battery․ Replace the battery immediately as described in the battery replacement guide․ If chirping continues after battery replacement‚ the alarm may be malfunctioning and require replacement․
If the alarm fails to sound during a test‚ check the battery’s expiration date and ensure it’s correctly installed․ If the battery is new and properly installed‚ the unit may be defective and should be replaced․ If the alarm sounds intermittently without any apparent cause‚ it could be due to electrical interference or a faulty sensor․ Try resetting the alarm by disconnecting it from the power source (if hardwired) and removing the battery for a few minutes before reconnecting․ If problems continue‚ consult a qualified electrician or contact First Alert support;
Never attempt to repair the alarm yourself‚ as this could damage the unit and void the warranty․ Always follow the manufacturer’s instructions for troubleshooting and maintenance․ Regular testing and proper maintenance are essential for ensuring the alarm’s effectiveness in detecting smoke and carbon monoxide․
