First Alert Smoke Alarm

First Alert PR710 10-Year Battery Powered Slim Smoke Detector with Photoelectric Sensor, Model P1210E. Brand new. The First Alert P1210 is a low-profile smoke alarm that uses a photoelectric sensor to detect smoke from slow-burning, smoldering fires. It has a slim, contemporary design that mounts unobtrusively on a wall or ceiling. The P1210E has a 10-year sealed lithium battery that provides up to a decade of uninterrupted monitoring. It is not a combination alarm and does not detect carbon monoxide. Photoelectric sensing technology is generally more sensitive than ionization sensing technology at detecting large particles, which tend to be produced in greater amounts by smoldering fires. These types of fires may smolder for hours before bursting into flame. Sources of smoldering fires may include cigarettes burning in couches or bedding. These are bargain priced at $25.00 but were purchased for $32.99 at Lowes for my grandmother only to find out that she had the fire department install some for her before my traveling to her home. You can find several shopping results for this product: eBay for $29.95, from Ace Hardware for $32.99, or from First Alert’s official website for $39.99. By buying these at $25.00 each, you are saving a whopping $64.00 for all eight. My loss is your gain.
