The TD-20U is the battery-powered sensor transmitter for the RCTD-20U (Wireless 2000). The detection pattern is selectable, allowing for a 17 foot fan pattern or 50 foot beam pattern, and sends a signal back to the RC-20U chime box when compromised. The device is powered by a standard 9V battery (not included), and up to nine TD-20U's can be added to one RC-20U receiver.
