Best Budget: First Alert Smoke Detector Alarm
The First Alert Smoke Detector is commendable in terms of its performance, convenience, and quality. This smoke alarm is designed with an ionization sensor, which helps to detect fast-flaming fires quickly and efficiently by alerting you with an 85-decibel sound alarm.
The system is hard-wired into your home, but also backed with 9-volt batteries; in case of any unexpected power outages, your alarms will still be operational.
Not to mention, the First Alert alarm can be interconnected with up to 12 compatible detectors, and six compatible devices such as bells, door closers, and horns. All units connected will go off once one system detects smoke, and you will be able to identify the first unit initiated by the latching alarm indicator.
Built with smart technology, the chances of having an accidental alarm triggered is slim to none. If there is a non-threatening detection, each unit has a silence button that quickly works to turn off the alarm. This button also provides single-testing to make sure your system is working properly and gives a low battery warning signal. It’s easy to install with universal mounting brackets and meets UL 217 standards.
