Optex TD-20U Indoor/Outdoor Sensor Transmitter for Wireless 2000 System
Key Features
  • Passive Infrared Detection
  • 9V Alkaline Battery-Powered
  • Detection Up to 50' Long and 17' Wide
  • Up to 2000' Transmission Range
The TD-20U Indoor/Outdoor Sensor Transmitter from Optex offers two selectable detection patterns, a 17' fan pattern or a 50' beam pattern. The sensor uses PIR to detect motion, and once motion is detected it sends a signal back to the RC-20U Chime Box Receiver using RF signals. The device is powered by a standard 9V battery (available separately) which can last for approximately 2 years when the sensor is triggered about 250 times a day. There is a red LED that indicates when the sensor has detected motion and when the battery is low. Up to nine TD-20U units can be added to one RC-20U Receiver, enabling you to set up a full perimeter around your property.

Using a flat head screw driver you push down on the section that the sticker that says Push points to and separate the casing from the sensor. Take out the old 9V battery and replace.

question

will this work as a replacement with a optex wireless 1000 chime system?
Asked by: Anonymous
Yes it is very similar to the older 1000 chime system that I had a long time ago in my other house. According to the features , in the TD-20U Sensor Transmitter Installation manual which can be found on the Optex company site it is compatible to the older 1000.
