  • What's Included
  • No longer do you need to be on the premises in order to monitor the status of the sensors around your home. When triggered by any of up to four external sensor switches, the 4-Channel Long-Range Transmitter will send a 10-watt, 27.255 MHz, digital-encoded, FSK-modulated signal to a companion receiver (sold separately), which will verify the digital code, activate its output, and trigger the remote device. A 1-channel, 4-channel, or 16-channel long-range receiver is required and sold separately. You'll also need a 3-foot whip antenna (sold separately).

    Fully Supervised Transmission
    The transmitter has full supervision capabilities. If the "status" option is selected, the transmitter sends hourly status signals to its receiver. If these signals cease, the receiver will indicate trouble by activating its status output after four hours. Contact supervision allows the receiver's outputs to follow the transmitter's inputs, staying activated as long as each transmitter input is activated. Alternately, an "auto-restore" option can be selected, causing a momentary receiver output each time any transmitter input is activated. Each input can be configured for either N/O or N/C contacts (switch selectable). Two 8-position switches set the unit's system code. This code must be matched in the companion receiver. There are 65,536 different system codes possible.

    Multiple Power Options
    Power for the transmitter can come from an external regulated 12 VDC power supply or from a 12-volt battery. If the power supply voltage drops below 10.5 volts, a low battery message will be included with any signal transmitted, causing the receiver's low battery output to activate.

    The transmitter is housed in a rugged weather-resistant metal enclosure with a sturdy SO-239 antenna connector and a water-tight wiring strain relief bushing. During transmissions, the red operation indicator (visible through a window on the case) lights. If the input voltage is low, the indicator will blink during transmissions.

    Review of 7426bx

    Worked great! Fairly easy to set up. I thought the hole size for external cables (power, sensors, etc.) should have been a little larger.
