1) Introduction
The D2xC1 is an ATEX, IECEx and UL certified Alarm Horn and Strobe
which produces a loud warning signal and bright visual 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 unit 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 Divison
2 / Class III Division 1 & 2. The beacon flashes at a set rate of 1Hz.
The D2xC1X05DC024 is also listed as Audible & Visual Appliances for
use in Fire Alarm Systems Private Mode in accordance with UL464
Tenth Edition & UL1638 Fourth Edition.
