To create the code you select, carefully use a sharp instrument to sever the
narrow part of the appropriate coding traces for each “OFF” position required.
In the example shown, the traces are shown as black and the circuit board is
shown as white. Traces numbered 1, 3, 4, and 6 are severed (“OFF”). Traces 2,
5, 7, and 8 are left intact (“ON”). Carefully observing polarity, replace the battery.
Replace the battery cover.

ET-1B

The Model ET-1B (emergency transmitter) is one of the smallest portable signaling
units in the Linear family of wireless security products. Measuring only 1.5 by .75
inches, the ET-1B can be worn on the supplied lanyard or attached to a keyring.
The transmitter is supplied with an adjustable lanyard with a breakaway release.
When activated by pressing both buttons, the ET-1B sends an alarm signal to
a companion receiver. The two-button feature provides protection against false
alarms. WARNING: Both buttons must be pressed for a minimum of two

seconds to cause receiver activation.

For security, the transmitter can be coded to one of 256 digital codes and is
compatible with all of Linear’s standard digital receivers. A miniature 12-volt
battery powers the transmitter and has an estimated life of one to two years.

DIGITAL CODING

The digital code for the ET-1B transmitter is selected by cutting “traces” on the
circuit board. All Linear ET-1B digital transmitters are shipped with all eight traces
un-cut, creating all “ON” codes. Cutting a trace changes the specifi c code to
“OFF”. CAUTION: To avoid false receiver activation, ET-1B transmitters must

be pre-coded by the installer prior to operation.

CODE SWITCH LOCATION

The digital coding traces in the ET-1B are located under the battery on the circuit
board inside the transmitter case. To access the coding traces and the battery,
gently pry off the soft-plastic cover and lift the battery out.

SYSTEM TESTING

PRODUCT DESCRIPTION

The manufacturer strongly recommends that you test security equipment
frequently, over a period of time. No electronic product is better than the
inspection and maintenance it receives. Therefore, from the time of installation, it
is absolutely necessary to test the system at least once a week.

Place the receiver in “TEST” mode and activate the transmitter. Verify that the
signal is received and that the system reports as required.

Linear radio controls provide a reliable communications link and fi ll an important need in por table wireless
signaling. However, there are some limitations which must be observed.

✴ For U.S. installations only: The radios are required to comply with FCC Rules and Regulations as

Part 15 devices. As such, they have limited transmitter power and therefore limited range.

✴ A receiver cannot respond to more than one transmitted signal at a time and may be blocked by

radio signals that occur on or near their operating frequencies, regardless of code settings.

✴ Changes or modifi cations to the device may void FCC compliance.
✴ Infrequently used radio links should be tested regularly to protect against undetected interference or

fault.

✴ A general knowledge of radio and its vagaries should be gained prior to acting as a wholesale

distributor or dealer, and these facts should be communicated to the ultimate users.
This device complies with FCC Part 15 and Canada Rules and Regulations. Operation is subject to the
following two conditions: (1) This device may not cause harmful interference and (2) this device must
accept any interference received, including interference that may cause undesired operation.
