This 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. First Alert Nuisance-Free Technology will reduce false alarms that result from cooking and shower steam. This smoke and fire alarm includes a loud 85db sound output, powerful LED indicator, end of life signal, mute and single test/silence button so you can test your alarm regularly. Installation is easy with the simple twist lock wall and ceiling mount. This smoke detector meets UL217 standards and is backed by a 10-year limited warranty. The First Alert Slim Design Battery-Operated Smoke and Fire Alarm is the perfect low-key addition for any number of home settings.
Photoelectric Sensor Warns of Smoldering Fires
The First Alert PR700 Smoke 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. It 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.
Sleek, Low-Profile Design
Half as thick as a standard alarm, the First Alert PR700 Photoelectric Smoke and Fire Alarm packs premium detection features into a sleek, compact unit. The ultra-thin design features a white finish that blends seamlessly with most home decor.
Battery-Powered Alarm Installs Easily
This battery-powered smoke and fire detector requires no rewiring and no electrician to install. Simply mount it on a wall or ceiling using the versatile twist-lock mounting bracket. An end-of-life signal will notify you when the detector is nearing expiration.
Alerts You to Danger
When a threat is detected, the smoke and fire alarm sounds a loud 85-decibel siren that is designed to wake even the soundest of sleepers. A single button allows you to silence alarms and test if the device is working.

It was easy to install with the good directions it came with. The slimmer alarm design is better and it has performed as expected for biweekly testing.

No Need for AC Wiring
I wanted to have both photoelectric and ionization alarms in the same room but I did not want a combination type smoke detector. Although I could not connect another AC powered alarm to my houses smoke detector network, this alarm was easily installed because it is battery powered, not battery backed-up.

I purchased the PR700 over the previous unit because unlike the replaced unit this one has a replaceable battery and I prefer a fresh battery on a yearly basis.

This smoke alarm is very easy to install. It is designed well. This is my second alarm and I'll buy it in the future.

Fills the Bill
I desire an alarm with a replaceable battery because the permanent 10 year battery models have failed to last more than 3 or 4 years. This model PR700 is just what I want and seems to work as intended.

Good so far
I tried this alarm after being dissatisfied with a different brand that I'd been using. The unit is in my kitchen and I'm hoping the photovoltaic version will result in fewer alarms, particularly when cooking bacon, which always set off my old one. This unit is thin and installation was easy.

Received and installed in less than 5 minutes. Newer units are very slim and blend well. Very pleased.

Good product, so-so compatibility
Bought this unit to replace previous model, which died as expected after about 11 years. This one seems equally high quality, and slim design is nice. My only complaint is that the new unit does not fit the old base, so that base needed to be swapped out, causing inevitable damage to our plaster ceiling. Make your products backwards compatible!
