A special timing circuit saves the 9-volt battery power by limiting the transmitting time.

When the WT-100 is triggered, it transmits for about 2 seconds, then inhibits itself for approximately one minute. If an input remains disturbed, the WT-100 will keep transmitting signals for a 2-second duration each minute, until the input reverts to the undisturbed state. The WT-100A is a single-shot (non-repeating) model that transmits only once upon each input trigger. The LED lights during the transmission period. A special circuit continuously monitors the battery voltage. If this drops below about 7.5 Volts, the transmitter automatically transmits a low battery alert signal for 1-2 seconds, to activate a buzzer in the target receiver. Low battery signals are repeated at one-minute intervals for a few days, depending on the remaining amount of battery energy. The LED lights during each transmission, identifying the unit transmitting the low battery signal.

Sensor will be connected between the Bat (-) and the N.O. or N.C. terminals, depending upon whether the sensor is normally open (N.O) or normally closed (N.C.)
