200 Series Universal Wireless Transmitter

The WT-100 is a general purpose, battery powered single-input transmitter for use with Normally Open (N.O.) and Normally Closed (N.C.) sensors and inertial vibration detectors. The transmitters signals are designed to work with the 200 series wireless receivers:



4-Channel (#7410)

2-Channel (#7411)

1-Channel (#7412)

A built in reed switch can be used with a magnet (not supplied) to protect a door or a window. An on-board tamper switch triggers a tamper alert (Channel 2) if the
front cover is removed from the base.



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.
