The Potter SPHX-DVSMR is a high-output explosion-proof speaker. First, it delivers tone and voice signals in hazardous locations. Then it broadcasts clear audio on supervised notification circuits. As a result, occupants hear alarms even in volatile environments.
Potter SPHX-DVSMR explosion-proof speaker features
The speaker driver and circuitry sit inside an explosion-proof housing. In addition, the cone and projector use spun aluminum. Therefore, the unit withstands demanding industrial conditions. Also, a supervisory DC coupling capacitor keeps the circuit monitored.
This speaker works on 25Vrms or 70Vrms audio systems. Specifically, selectable wattage taps range from 0.5 to 15 watts. As a result, installers can match output to each space.
