If the electrovalve opens when the "verify" procedure is enabled, its
activation confirms the discharge of extinguishant gas (refer to the
"confirm" option below).
During stand-by status, its activation generates a fault warning.
If this input is activated during the pre-extinguishment phase,
the extinguishment procedure will be aborted even if the input

The procedure can be restarted only after control panel reset.
If activated during stand-by, it will generate a fault warning.

This function is identical to the "Hold" function but refers to

External contact that inhibits gas discharge, etc.).
This activation will be signalled separately.
If activated during stand-by, it will not generate a fault warning.
It will activate only when the pre-extinguishment time expires
It will activate when the extinguishing channel is locked by one or more
