Linear SD 2-Button Handheld Transmitter, 2-Channel

The D-22B is a two-button, two-channel hand-held digital radio transmitter. The transmitter can perform a variety of remote switching tasks when used with any of Linear’s Standard Digital D" Series Receivers. Typically the D-22B is used in wireless or hybrid wireless/hardwire security systems.

The transmitter is powered by a 9-volt battery. Pressing the right button will send a Channel 1" signal, pressing the left button will send a Channel 2" signal. Hold buttons for at least 2 seconds to activate the transmitter. The red LED on the face of the transmitter will glow as the unit transmits and the receiver with the matching digital code will activate.

The Standard Digital radio format provides up to 256 different digital codes. The code is set using the 8-position coding switches in the transmitter and receiver.

D-22B transmitter switch key 1 is unused and can be set in any position. The transmitter pushbuttons control the signal that would normally be controlled by switch key 1. Pressing the right button sends a signal as if switch key 1 is OFF. Pressing the left button sends a signal as if switch key 1 is ON.

* CAUTION: All Standard Digital transmitters and receivers should be recoded prior to installation and operation.
