🔍 Quick Tip: Write today's date in the "Installation Date" field on the back of the alarm immediately after activation. This helps you track when the 10-year lifespan will end (manufacturing date + 10 years).
🏠 Where to Install Your Alarm
Proper placement is crucial for effective detection.
Recommended Locations:
Must-Have Placements:
Every bedroom - CO poisoning often happens during sleep
Hallway outside bedrooms - Central detection point
Each level of home - Basement, main floor, upstairs
Near attached garage - Car exhaust produces CO
Kitchen area - Smoke detection for cooking fires
Avoid These Locations:
❌ Direct sunlight - Can cause sensor degradation
❌ Bathrooms - Steam causes false alarms
❌ Near vents or fans - Airflow affects detection
❌ Corners of rooms - Dead air pockets reduce effectiveness
❌ Within 3 feet of cooking appliances - Too many false alarms
Ceiling vs. Wall Mounting:
Ceiling Installation (Preferred):
Smoke rises to ceiling
Most effective placement
Mount at least 4 inches from wall
Wall Installation (Alternative):
Mount 4-12 inches below ceiling
Never near floor (smoke rises!)
Avoid corners
🔍 Quick Tip: For multi-story homes, place one alarm on each floor even if bedrooms are only on one level. Fires can start anywhere, and early detection on every floor is critical.
🔨 Mounting the Alarm on Your Wall
Time to permanently install your alarm.
Tools You'll Need:
Pencil - Mark screw locations
Drill - Create pilot holes (optional but recommended)
Screwdriver - Install mounting screws
Level (optional) - Ensure straight installation

🔋 Understanding the 10-Year Battery
The sealed battery is both an advantage and limitation.
Advantages:
No Maintenance for 10 Years:
Zero battery replacements
No "low battery" chirping at 3 AM
Consistent power throughout lifespan
Ideal for elderly or forgetful users
Cost-Effective:
No ongoing battery purchases
Typical 9V batteries: $5-10 each
Replaced 1-2x per year in traditional alarms
Savings over 10 years: $50-$200
Environmentally Friendly:
Fewer batteries in landfills
Sealed design prevents leakage
One disposal event vs. 10-20 battery replacements
Limitations:
Cannot Replace Battery:
⚠️ Critical Limitation: The lithium battery is permanently sealed inside the unit. When it dies, you must purchase a new alarm—you cannot simply replace the battery.
10-Year Lifespan:
After 10 years from manufacturing date, alarm expires
Sensors degrade over time (not just battery)
Device will chirp/beep to indicate end-of-life
Even if battery lasts longer, sensors are no longer reliable
Disposal Considerations:
Must be disposed of properly (contains lithium battery)
Check local regulations for electronic waste
Some retailers accept old smoke detectors for recycling
🔍 Quick Tip: Set a calendar reminder for 9.5 years after installation to purchase a replacement alarm. This gives you a 6-month buffer to buy and install the new unit before the old one expires.
📅 Tracking Your Alarm's Lifespan
Knowing when to replace is critical for safety.
Important Dates to Track:
Manufacturing Date:
Found on back of alarm
Example format: "Feb 26, 2024"
This is your starting point for the 10-year countdown
Installation Date:
Write on back of alarm in provided space
Helps track how long it's been in service
May differ from manufacturing date if stored before installation
Expiration Date:
Manufacturing date + 10 years
Example: Manufactured Feb 26, 2024 → Expires Feb 26, 2034
Replace BEFORE this date, not after
How to Remember:
Strategy 1: Calendar Reminder
Add "Replace Smoke Alarm" to calendar
Set for 9.5 years after installation
Allows buffer time to purchase replacement
Strategy 2: Write on Alarm
Use permanent marker to write expiration date on alarm
Example: "REPLACE BY: FEB 2034"
Visible during monthly testing
Strategy 3: Set Multiple Reminders
Year 5: "Smoke alarm halfway to expiration"
Year 9: "Smoke alarm expires in 1 year - start planning"
Year 9.5: "Purchase replacement smoke alarm NOW"
▶️ Try This Now: Calculate your alarm's expiration date right now. Take the manufacturing date, add 10 years, and set a calendar reminder for 6 months before that date.
88% resolved. 22% stayed loyal. What went wrong?
That's the AI paradox hiding in your CX stack. Tickets close. Customers leave. And most teams don't see it coming because they're measuring the wrong things.
Efficiency metrics look great on paper. Handle time down. Containment rate up. But customer loyalty? That's a different story — and it's one your current dashboards probably aren't telling you.
Gladly's 2026 Customer Expectations Report surveyed thousands of real consumers to find out exactly where AI-powered service breaks trust, and what separates the platforms that drive retention from the ones that quietly erode it.
If you're architecting the CX stack, this is the data you need to build it right. Not just fast. Not just cheap. Built to last.
🎯 Top 3 Takeaways
Before we wrap up, here are the most important things to remember:
The 10-Year Battery Is Genius (With One Catch) 🔋
You'll never change batteries or deal with annoying low-battery chirps for an entire decade. This is perfect for high ceilings, elderly users, or anyone who hates maintenance. BUT—when the 10 years are up, you must buy a completely new unit. The battery cannot be replaced. Budget for a replacement in 2034!Test Monthly, Track the Expiration Date 📅
Press that Test button once a month without fail. It takes 5 seconds and could save your life. More importantly, write down the manufacturing date and set a reminder for Year 9.5 to purchase a replacement. Too many people forget until the alarm chirps at end-of-life.Know Your Emergency Plan BEFORE the Alarm Sounds 🚨
Fill out the emergency contact sticker, practice your escape route, and designate a meeting spot outside. When the alarm goes off (especially for carbon monoxide), seconds matter. Don't wait until an emergency to figure out what to do. Have the plan ready now.
❓ Common FAQs & Troubleshooting
Q: How do I know if it's detecting smoke vs. carbon monoxide?
A: The alarm will announce what it's detecting. Most models beep in different patterns: continuous beeping for smoke (fire), 4 beeps followed by a pause for carbon monoxide. Check your user manual for the exact pattern—it's critically important to know the difference!
Q: Can I install this in my kitchen?
A: You can, but install it at least 10 feet away from cooking appliances to avoid false alarms from cooking smoke. A better location is the hallway just outside the kitchen.
Q: What if the alarm goes off and there's no fire or CO?
A: This is a "false alarm." Press the Test/Silence button to silence it. Common causes: cooking smoke, steam from showers, dust buildup. If false alarms happen frequently, relocate the alarm away from the triggering source.
Q: How do I silence a false alarm?
A: Press and hold the Test/Silence button for 3-5 seconds. The alarm will beep 1-2 times and stop. Do NOT remove the alarm from the ceiling—investigate the cause and ventilate the area instead.
Q: Do I really need to test it every month?
A: YES. Monthly testing is the only way to confirm your alarm is working. It takes 5 seconds. Mark your calendar, test on the same day each month (like the 1st), and make it a habit. Your life may depend on it.
Q: Can I paint over the alarm to match my ceiling?
A: Absolutely NOT. The alarm clearly states "DO NOT PAINT." Paint will clog the sensors and prevent proper smoke/CO detection. If aesthetics are a concern, most alarms come in white which blends with standard ceilings.
Q: What happens at the end of 10 years?
A: The alarm will begin chirping to indicate end-of-life. You must purchase and install a new alarm. Remove the old one by twisting counterclockwise off the mounting plate. Dispose of properly per local electronic waste regulations. Install the new alarm on the existing mounting plate (if compatible) or install a new plate.
Q: Can I move this alarm to a new house?
A: Yes, as long as it hasn't reached its 10-year expiration. Remove it from the mounting plate (twist counterclockwise), pack carefully, and reinstall in your new home. Track how many years remain in its lifespan.
Q: Is this alarm interconnected/wireless?
A: This model is standalone—it does NOT connect wirelessly to other alarms. If one alarm sounds, others in your home will not automatically trigger. For interconnected alarms, you'd need to purchase a different model specifically designed for that feature.
Q: What if I accidentally pull the alarm off the ceiling?
A: Simply twist it back onto the mounting plate clockwise until it clicks. Test the alarm afterward to ensure it's still functioning. If it doesn't reattach securely or won't test properly, contact Exent customer support.
Q: Does this work during power outages?
A: Yes! The sealed lithium battery provides power for the full 10-year lifespan regardless of home power. Unlike hardwired alarms with battery backup, this is fully battery-powered and will work during any power outage.
Q: How loud is the alarm really?
A: Extremely loud—typically 85+ decibels. That's louder than a vacuum cleaner, similar to a lawn mower or blender. You will absolutely hear it from any room in a typical home. This is intentional—it's designed to wake you from sleep.
