Product Details
Linear Digital Radio Transmitter, 2-Channel, Lockout Feature
The D-22D is a two-button, two-channel hand-held digital radio
transmitter with a special lock-out feature. 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-22D is used in wireless or hybrid wireless/hardwire security
systems.
The transmitter is powered by a 9-volt battery. Pressing either
button will send a “Channel 1" signal, pressing both buttons 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-22D 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 either
pushbutton sends a signal as if switch key 1 is OFF. Pressing both
pushbuttons 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.
