DESCRIPTION
The T-90 is a supervised, digitally-coded radio transmitter designed
for applications such as door/window security. The T-90 is supervised
for alarms and restorals, low battery, status, tamper, and test. The
T-90 transmitter is compatible with any Linear SX format
supervised security receiver.
Coding switches are not required or used in the T-90. Each transmitter
is pre-coded at the factory to a unique code. With the SX format, there
are more than sixteen million codes possible.
The T-90 can be triggered with the built-in internal magnetic contacts,
with various types of external contacts, or both. When using one of
the internal contacts and the external input, both sensors must be
secured for a restore transmission, faulting either sensor will cause
an alarm transmission. External inputs can be either normally open
or normally closed.
Switch selected options are included for glass break sensors, built-in
pulse stretcher, battery saver, and external input type.
The transmitter is powered by two self-contained type 2032 3-volt
batteries. These batteries are supplied with the transmitter and have
sufficient life for most installations. Larger, type 2450 batteries can be
used to power the transmitter longer in high traffic installations. When
the battery voltage gets low, a low battery report is sent with any status,
alarm, tamper or test report to the receiver. Use only DL2450, or
CR2032 batteries.
STEP 1 Remove cover. Remove the T-90 transmitter
cover by twisting a small screwdriver in the top slot (the fat
end of the transmitter).

STEP 4 Pick transmitter location. Select a location for
the transmitter. Avoid mounting the transmitter near the floor.
Low level mounting can reduce transmission range and may
subject the transmitter to damage. Mounting the transmitter
on metal frame doors and windows is not recommended
because the radio range will be reduced.

STEP 10 Connect to terminals and set option switch.
Connect two wires from the external sensor to the external
contact terminals. Set the option switches for the type of sensor.
STEP 13 Program transmitter into receiver and test.
Follow the receiver’s instructions to set it in a program or learn
mode. Press the bottom of the transmitter case to send a test
signal. Verify that the signal was received and that the transmitter
was properly entered into
the receiver’s memory.
Set the receiver into a
monitor or chime mode.
Open the door or window
monitored by the
transmitter and verify
that the receiver accepts
the alarm transmission.
Close the door or window
and verify that the restore
signal was accepted.

IMPORTANT !!!
Linear radio controls provide a reliable communications link and fill an important need in portable wireless
signalling. However, there are some limitations which must be observed.
1 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.
1 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.
1 Changes or modifications to the device may void FCC compliance.
1 Infrequently used radio links should be tested regularly to protect against undetected interference or fault.
1 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.
