The YoLink Power Fail Alarm is a smart sensor that monitors the status of power to the device. If
power is ever removed or lost, the device will ac vate a very loud (100 to 110 dB) sounder, and flash
four mul -color LEDs. In addi on to a local alarm ac va on, the Power Fail Alarm can ac vate other
YoLink audible/visible alarms (for example, a Siren Alarm as a remote alarm device) and even
ac vate the SpeakerHub (for a spoken message a er an a en on-ge ng tone). Also, standard for most
other YoLink devices, the Power Fail Alarm, when power is lost, or when it is restored, can send the user
a text message, email and app push no fica on on their phone.
The Power Fail Alarm is powered by USB, which is provided from the included plug-in power
adapter. The Power Fail Alarm must have ba eries installed, in order for it to func on during
a power outage. Install new, name brand alkaline ba eries, or install new, name brand lithium
ba eries, which are highly-recommended, if the device will experience temperatures on the
extreme end of the environmental range (shown on page 24).
