Horns - Up to 108dB(A), Hazardous Location, Weatherproof

DB3 Range

ATEX

Architects and Engineers Specifications

This range of light weight all GRP, explosionprrof horns is intended 

for use in potentially explosive atmospheres and has been 

designed with high ingress protection to cope with the harsh 

environmental conditions found offshore and onshore in the oil, 

gas and petrochemical industries.
The flamepaths, flare and the body, are manufactured completely 

from a UV stable glass reinforced polyester. Stainless steel 

screws and sinter are incorporated thus ensuring a corrosion free 

product. A tapered flamepath is used to overcome the problems 

of assembly of parallel spigot flamepaths.
An optional Exe terminal chamber is available.

Sounder/Strobe

Combination Unit

Horns for hazardous locations and harsh environments shall be UL and cUL listed for Class I, Division 2, Groups A,B,C&D, and 

Class I, Zones 1&2, AExd IIC T4 applications and shall be listed under UL Standard 1638 for Indoor/Outdoor use. They shall be 

constructed of lightweight, UV stable glass reinforced polyester, shall be corrosion resistant, and shall meet NEMA 4x, NEMA 6, IP 

66  & IP 67 environmental requirements over a temperature range of -67°F to +158°F (-55°C to +70°C).

The horns shall have 27 user selectable output tones. Multiple horns shall be able to operate in synchronization. Rated current 

draw at 24 vdc shall not exceed 380 mA for rated sound output of 105 dBA at 10 feet. The horns shall include an integral volume 

control and a stainless steel mounting bracket with ratchet facility to direct sound output.
