Optex TD-20U PIR Transmitter

Battery-powered sensor / transmitter for the RCTD-20U (Wireless 2000) - The TD-20U Sensor/Transmitter is a PIR detector which will detect both people and vehicles. This weatherproof wireless indoor/outdoor sensor transmitter mounts easily wherever you need to know of people or cars arriving or leaving, and sends a signal back to the Optex RC20 Receiver (up to 2000') to alert you of visitors. It includes two detection patterns: fan or long range. The TD-20U is easily mounted behind a tree with its unique mounting capability.

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.
