Installation and Operation Manual
STI REPEATER
Thank you for purchasing this fine product. Your satisfaction is very important to us. Please read this manual
carefully to get the most from your new product.
HOW THE PRODUCT WORKS
STI offers wireless products designed to alert you of several different conditions. The STI REPEATER is a 433
MHz radio signal receiver and transmitter that effectively doubles the transmission range of STI sensors to STI
receivers. The REPEATER will filter out all radio signals that are not using 433 MHz STI protocol. When any STI
protocol signal packet (except STI 8-Channel Receiver) is received, it transmits the same signal packet. There is
no limit to the number of STI sensors that may be used with the STI REPEATER.
It should be understood that multiple REPEATERS should NOT be used within reception range of each other
because a REPEATER will simply retransmit any STI protocol signal packet (except 8-Channel Receiver). Two
REPEATERS within reception range of each other can retransmit signal packets back and forth a few times when
sensor packet is received.
If a dual REPEATER system or further extended range applications are needed, please purchase STI 8-Channel
Receivers (STI-34108). The receivers will retransmit alert and trouble notifications of the sensor signals, but not
the actual signals themselves. Therefore, REPEATER feedback will not occur. The receivers work with up to 8
different STI wireless sensors.
