Replacing wireless sensor with existing wired sensor on my GC3

Surety is a DIY Alarm.com service provider. We do not perform installation of devices and we do not send installers for maintenance.

If you are uncertain whether the wired sensor is physically wired properly to the TAKE-345, a good option might be to use the wired input of a DW10 Door/Window contact.

Your wired front door sensor could be wired to a DW10’s input, using the DW10 as a transmitter, nearby the door instead of at the Takeover module side. Alternatively, you could just try using a DW10 as a surface wireless contact on the door instead.

A similar use case to give you an idea how it works is found here:
