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 (incuded) 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.

Flexible logic so it can detect millisecond blips, (useful for computer equipment) or only report power outages longer than 10 seconds. Optional mode for a 15-minute delay for either the audible alarm or auxilliary output.
Auxiliary output can trigger an autodialer, wireless transmitter, or other remote devices. Can either supply 9VDC or provide a contact closure.
Includes a secure screw-mounting tab for critical process monitoring equipment, freezers, heaters, pumps, fans and more.
