TRANSMITTER		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,

		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.

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.
