Door Contacts:DC-9/DC-9SL

The MDC-3ZW is a discreet miniature door sensor that monitors the irregular opening / closing of doors and windows. The MDC-3ZW is particularly small, which allows for highly flexible and virtually invisible installation.

Integrating the MDC-3ZW into a security or home automation system will allow users to create scenes and automatically control lights and electronic appliances when doors or windows open and close. The MDC-3ZW features a pre-inserted battery with minimal power consumption, and transmits supervisory and low battery signals to check system integrity.

As a Z-Wave device, the MDC-3ZW can be flexibly integrated into new or existing Z-Wave systems.
