QNHS Explosion Proof LED Signal Beacon and Electronic Sounder

QNHS Explosion Proof LED Signal Beacon and Electronic Sounder

The QNHS series combines an LED signal beacon with a powerful electronic sounder in a durable explosion proof enclosure. It is designed for hazardous industrial environments where clear visual and audible warning signals are required.

The beacon supports multiple lighting effects, including steady, flashing, strobe and simulated revolving modes. Its long-lasting LED light source provides excellent resistance to shock and vibration while helping to reduce maintenance requirements.

The integrated electronic sounder offers a wide selection of warning sounds, special warning sounds, melodies, alarms and customizable voice messages. The standard QNHS model provides sound output up to 118dB at 1 metre, while the QNHS-H version reaches up to 123dB at 1 metre. Sound volume is adjustable.
