The power failure alarm continuously monitors 120V AC power outlets and if there is an interruption, the LED flashes and a 103dB beeping alarm sounds to let you know. The alarm can be silenced by pushing the green button. A selectable "snooze alarm" feature will cause the alarm to sound again every 30 minutes until the fault is corrected.
The only power failure device with plug detection; if your plug becomes unplugged from the power fail alarm itself, this is detected electrically and the alarm sounds.
Simple installation, just pop in the (included) long-life lithium battery. After that you are protected for the next 10 years.
Very loud beeping audio buzzer - 103dB at 2 ft will never be missed even in noisy factories.
Extremely low power consumption allows the lithium battery (included) to last up to 10 years**. Will alarm for 50 hours straight with the supplied Lithium battery. After that time, if battery power is low due to excessive alarming time, a low-battery warning alarm sounds for many weeks.
