Description:
This range of light weight, flameproof horns has been
designed with a high weatherproof rating to cope with the
harsh environmental conditions found offshore and onshore
in the oil, gas and petrochemical industries.
New electronic circuitry allows the DB1P and DB1HP to be
switched between two selectable tones by either reversing
the supply polarity, or connecting a second voltage supply.
The higher output are particularly suitable for noisy environ-
ments.
Architects and Engineers Specifications
Explosion-proof horns shall be UL Listed for Class I, Division 1, Groups C&D, and Class I, Zone 1 hazardous locations. The horns
shall be constructed of marine grade alloy with an epoxy paint finish and shall meet NEMA 4x and IP 66 environmental requirements
