Decent alarm. - 10/23/2013
Reviewer: Brian M.
No false hits yet. Although the light probably isnt strong enough to be of real use in a fire, its useful in quickly determining *which* alarm is sounding. I will continue to buy more of these.
Good basic alarm. - 10/20/2013
Reviewer: Brian M.
I like the photoelectric sensor alarms. Ive had several of these alarms in place for a few weeks and I havent had a false alarm yet. I went with this specific model for the light. The light is OK, but I question how useful it would be in a real fire as it isnt super bright what can you expect from a 9v battery? Thats OK, though, as I like the light feature mainly as a way to determine which of my alarms is sounding.

Q: How often do you need to change the batteries?
A: Actual battery service life depends on the particular design of your smoke or carbon monoxide alarm and the environment in which it is installed. All kinds of alarm batteries specified in the user's manual are acceptable replacement batteries. Regardless of the manufacturer's suggested battery life, you MUST replace the batteries immediately once the unit starts "chirping" (the "low battery warning"). It is recommended that you change the batteries in your alarms when you change your clocks for daylight saving time. Also consider replacing your current alarms with 10-Year Life alarms that never require a costly battery replacement for the ten year life of the alarm. This 10-Year series is available in smoke, carbon monoxide and combination alarms.
Q: What is the proper placement of smoke alarms?
A: It is important that you have the proper placement for your smoke alarms. Install your alarms at least 20 feet from appliances like furnaces and ovens, which produce combustion particles. Alarms should be at least 10 feet from high humidity areas like showers and laundry rooms, and at least 3 feet from heat/AC vents. Be sure to install a smoke alarm in each bedroom, one at the top of each stairwell, and one on every level.
Q: My smoke alarm keeps chirping and beeping. Why does my smoke alarm chirp intermittently?
A: It is likely that the reason your smoke alarm keeps chirping and beeping is that the battery is low. Whenever your smoke alarm keeps chirping, replace the battery immediately.
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.
Q: Why doesn't my smoke alarm sound when I push the test button?
A: It is important that you frequently test your smoke alarms. When you are testing your smoke alarm, there are a number of reasons why the alarm might not sound:
Q: Why does my smoke alarm go off when I install a battery or turn on the AC power?
A: It is normal for smoke alarms to go off and sound briefly (up to 5-10 seconds) when you install a new battery or when they are powered up. If the alarm continues to go off and no smoke is present, the cause may be one of the following:
Q: My smoke alarm keeps chirping, even with a new battery. What is causing this?
A: There are a number of possible causes for your smoke alarm to keep chirping even with a new battery.
Q: I lost my First Alert smoke alarm owner's manual. How can I get a new one?
A: First Alert smoke alarm owner's manuals are available online for download at no cost. Find your alarm in our Smoke Alarms section.
Q: Why does the National Fire Protection Association (NFPA) recommend that home smoke alarms be replaced after 10 years?
A: Smoke alarms have a limited life. Although each smoke alarm and all of its parts have passed many stringent tests and are designed to be as reliable as possible, any of these parts could fail over time. Therefore, you must test the devices weekly. The unit should be replaced immediately if it is not operating properly. The performance of smoke alarms older than 10 years is simply not reliable. To ensure your family's safety, all carbon monoxide and smoke/CO combination alarms need to be replaced every 5-7 years. All smoke alarms need to be replaced every 10 years.
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.
Q: I'm ready to change my alarm battery - what replacement batteries can I use?
A: Check your User's Manual or the nameplate on the back of the alarm. Different smoke detectors & CO alarms use different kinds of batteries - 9V, AA, AAA - it all depends on the particular model you have. Use quality batteries like lithium batteries - having plenty of power is worth any extra cost. Never use rechargeable batteries because they may not always provide a consistent charge.
