First Alert Photoelectric Smoke Alarm - P900
Photoelectric Smoke and Fire Alarm
The First Alert P900 Smoke and Fire Alarm provides maximum protection and has a new sleek, slimmer design, which adds an element of style to safety. The P900 has a modern, thin square design that's less than an inch thick (half the size of a standard alarm), while still providing all the protection you need to keep what matters most safe and secure. The P900 Maximum Protection Alarm has a patented smoke entry system that allows a direct smoke path to the photoelectric sensor to detect regular and slow, smoldering fires.
Photoelectric Sensor Warns of Smoldering Fires
The First Alert P900 Smoke and Fire Alarm comes equipped with a photoelectric sensor to provide the earliest possible warning of fire. The sensor is optimized to detect larger smoke particles produced by smoldering fires, such as those caused by unextinguished cigarettes. This smoke and fire alarm also distinguishes between real threats and smoke/vapor produced during showering, cooking, and other everyday activities, helping minimize the number of false alarms. A patented smoke entry system helps ensures reliable detection by providing a direct air pathway to the sensor.
Modern, Sleek Design
Unlike older, bulkier detectors, the First Alert P900 Photoelectric Smoke Alarm features a modern, thin design that can be unobtrusively mounted on a wall or ceiling. The sleek white finish coordinates seamlessly with most home decor.
* California Residents - Please Note This Alarm is Not Compliant with California State 10 Year Sealed Battery Alarm Legislation Requirements.
Other reasons include: It could be a different device or appliance such as a security system, monitor, carbon monoxide alarm, or other device which has a similar low battery or alert signal. Some of the same factors that cause unwanted alarms can cause intermittent alarms: dust and insects in the alarm or power interruptions in hardwired alarms. Improper wiring on AC or AC/DC smoke alarms. AC alarms will chirp every 5 seconds if the interconnect wire is grounded. The orange interconnect wire should NEVER be grounded; it should only be used to interconnect other smoke alarms or compatible devices.
- You may not be holding the test button down long enough. Try holding it down for up to 10 seconds (20 seconds on photoelectric models) .
- Your battery may not be installed properly or snapped all the way in place. Even if the alarm sounded briefly when the battery touched the terminals, you still need to make sure it is snapped securely in place. If the battery is loose, in cannot power the smoke alarm properly. After installing new batteries, be sure to test your smoke detector.
- Your AC power may not be on. AC and AC/DC units will have a power indicator light (red or green) that shines continuously when they are receiving electrical power.
- If you have a 10-Year model, the smoke alarm may not have been properly activated. If the tab broke away before the alarm was activated, you can use a toothpick to move the switch over to test the alarm.
- There may be insufficient battery power, try new batteries.
- Problems with voltage or insufficient electrical power (brown out) may cause a continuous weak sounding alarm. For AC or AC/DC models, temporarily disconnect power at the service panel until the brown out is over. If you do not restore the AC power, your smoke alarms cannot warn you of a fire.
- Incompatible warning device. If an incompatible alarm or auxiliary device is linked into a series of AC or AC/DC smoke alarms it may cause the system inadvertently go off.
- It is possible that your smoke alarm "silence" button was pushed by mistake. The alarm will now "chirp" once a minute for up to 15 minutes before resetting.
- Are you sure it's the smoke alarm? Funny to ask, but other devices have similar low battery chirps or warning tones.
- Your "new" batteries may not be fresh. If batteries are stored, especially in cold areas like refrigerators, they lose their charge more quickly. Always check the freshness date on the package when buying new batteries. Keep plenty of replacement batteries on hand so that you are sure to always be protected by your smoke alarms.
If it's time to replace your alarms, consider the NEW 10-Year Life series and never have to worry about a battery replacement for the life of the alarm.10-Year alarms are available in smoke, carbon monoxide and combination alarms.

We bought this product because First Alert carries many options for photoelectric smoke alarms, which are recommended. We love the low profile.

I ordered this alarm after seeing the feature on Photo vs Ion sensing technology on the Today show. This alarm meets those requirements and was really easy to install.
