Compact fault annunciator ESS 8 and ESS 12 Compact fault annunciator for 8 or 12 inputs › EES 8 modular expandable up to 80 inputs › Triggering of signalling lights or tableaux › Supply voltage and signalling voltage equipotential › Phase arbitrary drive of the reporting inputs › Horn and lamp reports with single acknowledgement › No activation of horn and collective reports by lamp test › Terminals pluggable

Functional description The fault annunciator devices ESS 8 and ESS 12 are compact and reasonably priced new value reporting devices providing collective report formation and horn triggering as well as potential-free output contacts for driving signalling tableaux. By external attachable push buttons both the reports themselves and the horn can be acknowledged and also a lamp test can be executed. The contacts for horn and collective reports are designed as potential-free NO contacts. If an alarm lines up longer than the response delay, the corresponding indicator lights up, horn and collective...
