QNVS Explosion Proof LED Signal Beacon and Electronic Sounder

QNVS Explosion Proof LED Signal Beacon and Electronic Sounder

The QNVS series combines a high-performance LED signal beacon with an electronic sounder in a durable explosion proof enclosure. Designed for hazardous industrial environments, the unit provides both visual and audible warning signals and is suitable for applications requiring clear indication and high sound output.

The signal beacon supports several lighting modes, including steady, flashing, strobe and simulated revolving light. The long-life LED light source offers excellent resistance to shock and vibration while helping to reduce maintenance requirements.

Depending on the selected model, the electronic sounder provides sound output of up to 118dB for QNVS and up to 123dB for QNVS-H at 1 metre. The volume is adjustable, and multiple sound options are available, including warning sounds, special warning sounds, melodies, alarms and customizable voice messages.
