The Optex TC-10U door contact wireless transmitter is an easy way to add an extra level of security to your Optex system. It can be installed on either a door or window and has a 700 foot transmission range. Weatherproof design means that you can place the unit indoor or out (not in direct rain).

In addition to acting as a door/window sensor, the TC-10U can be installed in the backbox of any of Optex's battery operated, wireless-ready detectors for extended detection range and wireless notification to your RC-20U chime box.
