Gizmo Engineering PFA-2 Power Failure Alarm, 10ft Relay Output

Features:

• A selectable "snooze alarm" feature will cause the alarm to sound again every 30 minutes until the fault is corrected.
• The only power outage alarm with a plug detection alarm. If your plug becomes unplugged from the power fail alarm itself, this is detected electrically and the alarm sounds.
• Simple installation, just snap in the long-life lithium battery thats included. 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.
• 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 auxiliary output.
• Operates from 120VAC power.
• Includes a 10ft relay output wire. Can be N.C. or N.O. Relay output is a sustained contact close for the same duration as the power outage. Useful for connection to building alarm systems.
