Product Description

Amazon.com

Working smoke alarms cut the risk of dying in a home fire by 50%, and that's important because a home fire starts every 83 seconds! The faster you know about a fire, the faster you can start moving your family outside. The First Alert smoke alarm with photoelectric sensor uses photoelectric sensing technology which is environmentally friendlier and which reduces nuisance alarms, making it ideal for cooking areas. It is also great for sensing slow smoldering fires quickly. It features a low battery alert to remind you when to change the battery and has a missing battery guard to ensure that a battery is placed inside the alarm. The side battery drawer slides open for easy battery replacement. A blinking power indicator on the unit confirms that it is receiving power. The silence/test button allows you to both silence a non-threatening alarm and to test the unit's functionality. The alarm contains an optional pin to lock the battery and unit in place for tamper resistance. It can be mounted on either the ceiling or the wall and can be used in mobile homes and RVs. It includes one 9-volt battery and has a 10-year limited warranty. UL listed for safety and approved for sale in Oregon.--Bree Norlander

What's in the Box
One smoke alarm, user's manual, and one 9-volt battery

I had to replace some very old smoke alarms and bought four of these. They use photoelectric detectors, which are less prone to false alarms, and are more effective and more environmentally friendly (see next paragraph). They come with a universal mounting bracket with holes to fit most preexisting screw arrangements. I had two different types of mounting patterns across the four alarms I replaced and the bracket had holes to effectively fit both patterns. Installation was simple. The alarm twists onto the mounting bracket, making removal simple as well, but there will likely be little reason to remove it until it's time to replace them, as the battery is easily accessible from the slide-out tray while the unit is mounted. Both the mounting bracket and the battery tray can be locked using included locking pins, although I had no reason to test that feature. The test/silence button worked as expected on all four. I also have a First Alert SC07CN Combination Smoke/CO Alarm with Voice Location, which I like, and these smoke alarms are similar in form factor and size--which, at 5" in diameter and 1.9" thick, is a little bit larger in both diameter and thickness than either type of units they replaced in my home. The one minor disappointment with these smoke alarms is that despite resembling the SC07CN in form factor and using the same slide-out tray for the batteries, these alarms run on 9-volt batteries instead of the AA batteries like the SC07CN.

[Edit 3/21/14 - I updated the following paragraph to be clearer, and more specific and balanced]
If you're getting a new smoke detector, be sure to get a photoelectric or dual-sensor detector.

This alarm, like other First Alert/BRK products works fine for about a year, and then the fun begins. Falses randomly, at all hours. We've been awaken at least FIVE times in the past month for false alarms. No other product has the track record First Alert Alarms do. They also have an unsatisfactory BBB record. No wonder, the thieves want to charge me $6 shipping to replace THEIR defective unit. Go with another brand, unless your alarm clock is broken

Terrible, just terrible. My unit went off on a false alarm, and I practically had to tear it apart to get it to silence. Since the bracket is mounted on my wall, I just went ahead and bought a new unit that was exactly the same. That one malfunctioned as soon as it came out of the box. Even with a brand new battery, it wouldn't stop chirping with the low battery signal. It's a piece of junk.

We bought this to replace a very old ionization type alarm that stopped functioning properly. There are so many alarms out there that it required some research to decide what to buy. Ideally one wants it to work well and continually (it could save your life, after all) while not being overly expensive. I think this one fits the bill.

The big issue these days is whether to buy an ionization type alarm or one with a photoelectric sensor. I opted for the latter. This is why (I'm quoting from an article which cites the professional opinion of the fire chief of Albany, CA):

"An ionization alarm contains a tiny amount of radioactive material to set up an ionization chamber that creates an electric current. When the current is disturbed by smoke, the alarm sounds. It costs about $10. A photoelectric alarm, in contrast, contains a small beam of light. When smoke disturbs that beam, the alarm sounds. It costs about $15. The difference has to do with how smoke from different fires moves through the air and what is in that smoke. For example, an overcooked dinner may produce small particles of smoke that waft through the air. The ionization alarm is sensitive to those tiny flecks, prompting false alarms. The photoelectric alarm can tell better when there isn't enough smoke to be a dangerous fire. On the other end of the spectrum is the smoldering fire, which produces bigger particles. Those aren't as easily detected by the ionization alarm until the smolder becomes flames that produce the smaller particles. Virtually all residential homes with smoke alarms have the ionization type, and virtually all commercial buildings have the photoelectric types, according to several studies.

I have owned this for 6 months or so. It works just fine, just like it should. I have it placed in my kitchen, so I was waiting for it to be going off all the time from steam, but it doesn't. It went off for the first time last night, a piece of popcorn dropped onto the burner and it smoked up and the alarm went off. Does the job!

We replaced our oldest smoke detector, an ancient Honeywell ionization detector that was probably thirty years old. It still functioned but was prone to false alarms.

The First Alert SA710 was in service for less than six months and then failed. The detector chirped indicating that the battery needed replacement, I've tried four new nine volt batteries, the chirping continues and the test button now does nothing. The detector failed.

Zero stars is the appropriate rating for a safety device.
