Midland Radio 74-200 manual NWR Alert Descriptions

received. The 74-200 provides a switch closure to signal other devices at the EXT. ALERT jack when the radio receives an alert. The output is compatible with home automation devices from suppliers like X-10 and others. Connect the positive lead of the interface to the tip of the 1/8 inch (3.5mm) phone plug and the negative lead to the body of the plug.

A DC powered device using 12 Volts or less and requiring less than 300mA of current can be switched directly using the EXT. ALERT jack. Observe the polarity of the jack so that the negative side of the external power source is connected to the body of the

1/8 inch (3.5mm) phone plug and the device is connected to the positive source and to the tip of the phone plug.

The internal switch is closed when an alert is received. Pressing the OFF button on the front of the radio will open the switch. For best control of external devices we recommend using the ALERT only mode as opposed to the VOICE mode.
