Latch M, C, C2, and E-Genius
Latch M, Latch C, and Latch C2 are battery-powered and will continue working during a property-wide power outage. If your M Series (Generation 2) is wired and there is a power outage, it will switch to battery power automatically and revert to wired power when the power is restored.
Latch R
Latch R needs a constant power supply to function. We recommend a backup power source for R devices to avoid losing functionality during an outage.
If power sources change and when power is restored, it is crucial to promptly update the reader to avoid disruptions to guest access and schedules.
Fail-safe and fail-secure
Proper wiring and programming of the R device are essential to ensure it behaves as fail-safe (unlocked) or fail-secure (locked) during a power loss, depending on the door hardware.
We recommend seeking guidance from your property installer for assistance with these settings.
