Linear Home Security System T 90 User Manual

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.

T-90  
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.
