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 2 Remove battery protection strip. Pull the battery
protection strip out from underneath the battery clamp.
STEP 3 Identify transmitter components. Examine the
transmitter to identify the component locations.
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 5 Remove mounting plates. Use a small
screwdriver to remove the transmitter’s mounting plate.
Squeeze the magnet’s tabs to remove its mounting plate.
IF USING EXTERNAL CONTACTS, SKIP TO STEP 8
STEP 6 Select switch side. Place the internal contact
jumper on the pins closest to the transmitter side on which the
magnet will be.
