Potter SPHX-DVSMR Explosion-Proof Speaker 25V/70V Red

Potter SPHX-DVSMR CPG Signals PowerTone Explosion-Proof Speaker

The Potter SPHX-DVSMR CPG Signals PowerTone is a rugged explosion-proof speaker designed for audible emergency notification in hazardous locations. Engineered for demanding industrial environments, the speaker delivers crisp, clear, high-decibel tone and voice output when connected to compatible 25 Vrms or 70 Vrms audio systems.

Designed for supervised alarm notification circuits, the SPHX-DVSMR incorporates a supervisory DC coupling capacitor and selectable wattage taps ranging from 0.5 to 15 watts, providing flexibility for different sound coverage and system design requirements.

The speaker cone and projector are manufactured from spun aluminum, while the speaker driver and associated circuitry are protected inside an explosion-proof housing. Its weatherproof and corrosion-resistant construction makes it suitable for both indoor and outdoor installations.

Finished in red enamel and rated NEMA 3, the SPHX-DVSMR provides a durable notification solution for facilities where standard speakers may not be appropriate due to hazardous environmental conditions.
