Latch M and Latch C
Building power outages
Latch M and Latch C are both battery powered and will work as normal in the event of a building-wide power outage. Learn more about battery power.
Loss of power
If the Latch M or Latch C lose power, during battery replacement for example, it is important that they are immediately updated. Failing to update the device after power loss may cause disruption to guest access.
Building power outages and loss of power
Latch R requires a constant power connection in order to work. In the event of power loss, due to a building-wide outage for example, it is important that it is immediately updated once power resumes. Failing to update the device after power loss may cause disruption to guest access and Schedules.
Fail-safe and fail-secure
It is important that the R is correctly wired and programmed in order to fail-safe (stay unlocked) or fail-secure (stay locked) in the event of power loss. Please consult your building installer for guidance.
