Optex TD-20U Wireless Pir Transmitter

Product Description

The OPTEX TD-20U is a wireless passive infrared (PIR) transmitter designed for use in security and detection systems. It converts PIR sensor signals into wireless transmissions, allowing motion detection data to be sent to a compatible receiver or control panel without hardwired signal runs. This unit is sold individually and is typically installed by licensed security technicians or qualified electricians working on low-voltage detection systems.

The TD-20U is suited for residential and light commercial security installations where wireless signal transmission from a PIR sensor is required. It is intended for use in applications where running wire to a detection zone is impractical, allowing flexible sensor placement throughout a facility or dwelling.
