Optex Door Chime
The Optex TS-10U Wireless Transmitter can be used in conjunction with the Optex RC20 Receiver as a wireless door chime system. You can even add an Optex TD20U driveway sensor to the kit and have both a driveway and door bell chime for dual notification of visitors! Even have different chime tones to distinguish between visitors at the door and vehicles entering your driveway!
The TS10U door chime has a 700' wireless range and there is an Optex Wireless Repeater available if longer range is required!
NOTE: All Optex Wireless 1000 and 2000 Products are compatible together, this unit will work with TD-10U's and RC-10U chimes as well.
