security technology to prevent anyone from stealing your code and using
it to gain entrance to your home.

wall station in the dark.

1-Channel Block Coded Key Ring Transmitter
The Model ACT-31B 1-Channel Block Coded Key Ring Transmitter is
designed for use with Linear's access control products. The Model
ACT-31B is a single-channel device supplied with a quick-disconnect key
ring. Also included are lithium batteries with a five-year service
life. A unique 10-second time-out feature prevents the system from
being shut down by a single transmitter transmitting continuously.
The transmitter is MegaCode format, which means each transmitter is
factory preprogrammed with one of over 1,000,000 codes, virtually
eliminating the possibility of code duplication. Because the receiver
"learns" each specific code, no unauthorized person can gain access to
the system by reprogramming a transmitter.
Block coded transmitters are factory programmed to a sequential series
of transmitter ID codes. When used with a Linear access controller,
transmitters can be locally or remotely programmed into memory by
entering the first and last codes of the block into the system.
Facility codes can be selected to further customize the system.

transmitters and receivers do not contain a typical "coding switch".
Each transmitter is permanently coded at the factory. The transmitter
sends a unique code when the button is pressed. The receiver is
programmed by learning a transmitter's unique digital code. The
receiver will activate only from the memorized transmitters.
transmitter is powered by two Type 2032 coin-cell batteries. They
should last 3 years with normal use. The red indicator on the face of
the transmitter will glow when the unit is activated. If the indicator
lights dimly, or not at all when transmitting, the batteries need to be
replaced. To conserve battery life, an internal timer limits the
transmission duration to 10 seconds if the transmitter button is held
down. 3-Channel Visor Transmitter The MCT-3 3-channel Visor Transmitter is a wireless radio control designed for use with automatic garage and gate operators.
Each of the three transmitter buttons will send a unique code when
pressed. One button can be used to activate the individual's garage
door opener, a second button can operate an access gate, a third button
can activate an additional garage door operator or most Linear 318 MHz
MegaCode wireless receivers.
