EN54 section 7.12 Dependencies on More Than One Alarm Signal
7.12.1 Type A dependency (option with requirement)
Following the receipt of a first alarm signal from a fire detector, the entry to
the fire alarm condition may be inhibited until the receipt of a confirmation

receipt of the first alarm signal;
information on the values of the configured delay times shall be accessible
at access levels 2 or 3.
