INSTRUCTION & SERVICE MANUAL
D2xS1 ALARM HORN
For Use In Hazardous Locations
1) Introduction
The D2xS1 is an ATEX, IECEx and UL certified alarm horn
which produces a loud warning signal in a hazardous area.
Sixty-Four first stage alarm sounds can be selected by internal
switches and each one can be externally changed to a second,
third or fourth stage alarm sound. The alarm horn may be used
for Gas applications in Zone 2 / Class I Zone 2 / Class I,
Division 2 as well as for Dust applications in Zone 22 / Class II
Zone 22 / Class II Division 2 / Class III Division 1 & 2. A D2xC1
combined alarm horn & strobe is also available. The 24Vdc
version is also listed for use in fire alarm systems –public
mode.
