Overview

The Federal Signal 300VSC-1 SelecTone Desktop Command Unit (SKU 300VSC-1) is a UL and cUL certified control device designed for fire alarm and general signaling applications. It supports dual voltage operation—24 VDC or 120 VAC—enabling flexible integration into new or legacy systems. The unit generates up to four prioritized tones or voice communications via an illuminated keypad, with public address capability activated by an optional desktop or hand-held microphone. Priority levels are structured as public address (highest), tones 1-4, remote microphone, and auxiliary audio. The 300VSC-1 features a Type 1 enclosure for indoor use, supports remote operation via external dry contact closures, and includes a monitor speaker for test functions. Tone output levels reach 10 Vrms (unbalanced) or 25 Vrms (balanced, 40 Ohm max), with a signal-to-noise ratio under 1.5% THD. The device weighs 3.1 lbs (1.4 kg) and measures 3.5" x 10" x 10" (HxWxD). Certified for CSA and UL, it is ideal for weather warnings, evacuation, paging, and factory signaling. Compatible with UTM and TM33-SD tone modules, the 300VSC-1 ensures reliable operation with low standby current (0.03 A at 120 VAC) and emergency power backup support via PS250, PS600, or PS1000.
