Clock Battery

Rechargeable battery 3.6V, battery life is not less than 10 years

Communication battery

The rechargeable battery adopts 4.8V rechargeable battery or battery pack, with rated capacity ≥ 600mAh. After power failure, the battery can work alone to maintain the terminal running time of not less than 5min.

Terminal power failure

The terminal can record the last ten power outage events and report them to the main station.

Switching quantity input

The switch input interface adopts the passive node mode. When the external contact connected to the remote signal terminal is closed, the remote signal level is valid, and when the external contact is disconnected, the remote signal level is invalid. The remote signal input shall have anti-shake function. The default anti-shake time is 20ms, the parameters can be set (10ms ~ 6000ms ), and the resolution is 5ms.
