Pros & Cons
The First Alert Double Sensor Battery – Powered Smoke and Fire Alarm is equipped to detect smoke particles caused by both flaming and smoldering fires. The dual smoke sensors with both photoelectric and ionization smoke sensing technology helps determine the difference between non-threatening conditions and real emergencies. It also features a convenient single button operation for testing or muting non-emergency alarms. This unit gives an easy access to battery door, enabling easy battery replacement without completely being removed from the ceiling. It uses two AA batteries (included).
However, like most of the alarm devices this unit also chirps frequently and gives false alerts. Some also felt that the alarm sound produced is muffled and might be difficult for elderly individuals to listen and react accordingly.
Overall, the First Alert Double Sensor is a recommended unit for single floor houses for its easy to use functionality and affordable price. It is backed with 10 years warranty and meets UL217 standards.
