Product Overview

Add safety and convenience to your home, cottage or business. When linked to an Ideal automatic telephone dialer the SK640 will notify you by telephone of a power failure and trigger a 30 second built in alarm (BiBiBi). When plugged into a 110-Volt outlet, a blackout, power failure or circuit interruption, will trigger the included batteries to power the unit to send a signal to a dialer, an alert or an Ideal wireless siren. A land telephone line is required for the calling feature. The SK640 is designed to be left plugged into an outlet at all times. The SK640 includes the sensor; a UL approved adapter, 3 AAA batteries, instructions and wall mounting screws. The low battery LED will flash and a “di-di” sound will be heard to remind you to change batteries to ensure continued service. The sensor can be used with the alarm sound or in silent mode. The wireless signal will be sent in either mode.

  • Power failure triggers signal to be sent to dialer, alert or siren
  • Built in 30 second alarm or silent mode
  • 3 AAA bateries included

Customer Questions & Answers

Will this detect a power outage on a single receptacle such as the one a freezer is plugged into???

No, this will not alert you to failure of a single outlet.

Does the alarm sound immediately, even is the power loss is only for an instant, or is there a time delay that requires power to be lost for several seconds before it activates?
Asked by: Potter
The alarm will sound immediately when AC power is interrupted by a fraction of a second. There isn't any count down/waiting period. The triggering signal will be sent out immediately also.

Do I need to purchase the telephone dialer separately to get phone notification of power failure?

Asked by: willewis
Yes you would need the SK618 Auto Dialer in order to receive telephone notification of a power failure.

land line ??

Uum, what is a land line, one of those things from pre 1980 ? When will a real wireless solution be available for my cell phone. ?
Asked by: CloggedUp
The SK640 power failure sensor will send a wireless signal to the SK618 dialer once the AC power fails. And the SK618 will dial out pre-programmed phone numbers powered by its backup batteries. This solution makes sense because most of the wifi routers/hubs don't have power backup when AC power fails.
