Essential Info

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.

  • More Info

    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.)
