Through proven performance, patented VT Series fire protective signaling speakers have earned worldwide acclaim for service reliability. Inside every VT speaker is a small compression driver capable of high sound pressure levels, and the die-cast, water-sealed construction withstands vandalism, vermin, moisture, corrosion, and vibration during indoor or outdoor use.
An internal DC blocking capacitor enables the VT to work on supervised speaker lines, and speaker wiring terminates on a barrier strip. Optional mounting accessories are offered including: indoor and outdoor enclosures, a bi-directional housing, adapter plates and rings. Neutral Gray Finish
