ALARM
– technical output of collective failure indication.
Output indicating collective failure. In the case of failure at any EPS, APS, or PSU output or at the EXTi
input, the collective failure signal ALARM will be generated.
CAUTION!
In Fig.21 the set of contacts shows a potential-free status of the relay, which
corresponds to power supply failure (collective failure of the PSU).
EXTi - technical input of collective failure.
The EXTi technical input (external input) indicates the collective failure and is designed to connect the
ALARM indication of collective failure from another DSO cabinet.
The indication of collective failure is used in complex systems consisting of several DSO cabinets and
allows sending a single failure signal to the fire system control panel.
