Imagine installing a battery-operated smoke detector that communicates with other detectors around the house so they all go off at the same time — just like hard-wired smoke alarms. Now give them a voice telling you where the smoke is located and you’ve got First Alert’s ONELINK Talking Wireless Alarm.
The ONELINK alarms talk to each other over radio frequency 914 MHz and shouldn’t interfere with other wireless electronics. They detect smoke via photoelectric sensing, which is more environmentally friendly and less likely to cause false alarms.
Best of all, the detectors actually use cheap AA batteries which are included with the alarm, instead of relatively expensive 9V batteries, so changing the batteries every six months when you’re supposed to won’t cost $20 a year.
You can get a pair of smoke alarms for about $90 or a combination CO and smoke alarm for a little over $70.
