'Extinguishing terminal' – 'LED' – 'Local event' elements
The table below describes the configurable causes which light up the assigned
LED on the extinguishing terminal. An 'Local event' element represents a cause in
each case.
Designation Description
'External release activated'
Extinguishing for the associated flooding zone has been triggered from another
flooding zone.
Activation state: 'External release activated'
'Emergency hold indication'
An interruption of the pre-warning time before the triggering of an extinguishing
process is active.
Activation state: 'Emergency hold indication'
'Emergency hold device
activated'
An 'Emergency hold' switch has been operated.
Activation state: 'Emergency hold device activated'
'Emergency abort
indication'
Emergency extinguishing switch-off is active.
Activation state: 'Emergency abort indication'
'Emergency abort device
activated'
An 'Emergency abort' switch has been operated.
Activation state: 'Emergency abort device activated'
'Loss of agent'
The extinguishing system has detected a loss of extinguishing agent in the main
extinguishing agent cylinders or in the reserve extinguishing agent cylinders.
Activation state: 'Loss of agent'
'Loss of main agent'
The extinguishing system has detected a loss of extinguishing agent in the main
extinguishing agent cylinder.
Activation state: 'Loss of main agent'
'Loss of reserve agent'
The extinguishing system has detected a loss of extinguishing agent in the
reserve extinguishing agent cylinder.
Activation state: 'Loss of reserve agent'
'Reserve cylinder bank
selected'
The reserve extinguishing agent cylinder has been selected for extinguishing.
Activation state: 'Reserve cylinder bank selected'
'External equipment OFF'
The external systems which are connected using control technology, e.g., a
ventilator system, are switched off.
Activation state: 'External equipment OFF'
'Mechanical release
activated by pressure
switch'
The pressure switch has detected an extinguishing agent flow. Extinguishing is
activated mechanically.
Activation state: 'Mechanical release activated by pressure switch'
'Sensor activated' A connected sensor was activated.
The LED would light up if a CO
2
sensor detects this gas, for example.
Activation state: 'Sensor activated'
'Programmable input
