Features

The Federal Signal Model 300SCW-1 SelecTone® Command Unit generates up to four tones or voice communications through a SelecTone system. Four tones, auxiliary, test and cancel are controlled via an illuminated keypad. Voice transmission is activated by keying the optional hand held microphone.

Public address can be accessed from the optional local microphone or via the remote microphone input. Public address has the highest priority, followed by tones 1-4, remote microphone and audio.  “Test” plays tones or voice messages through the monitor speaker only. “Cancel” interrupts any tone. External dry contacts can be wired into the command unit for automatic remote operation of the signal system.

The Model 300SCW-1 SelecTone Command Unit is the basis for a simple, versatile general signaling system for weather warning, start and dismissal, general alarm, evacuation and paging. Federal Signal’s SelecTone Model 300SCW-1 Command Unit allows up to four tones and public address capability to be prioritized and broadcast through a SelecTone system.
