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 alarm signal from the same fire detector, or from a fire detector in
the same zone. In this case, the first alarm state need not be indicated, and the following shall apply:
a) the mode of operation shall be configurable at access level 3 for individual zones;
b) reception of a confirmation alarm signal shall not be inhibited for more than 60 s following the receipt of
the first alarm signal. The manufacturer may specify a time shorter than 60 s. In this case, this
specification shall be tested and verified;

d) information on the values of the configured delay times shall be accessible at access level 2 or 3.
7.12.2 Type B 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 alarm signal from the same fire detector and/or from another fire
detector, which may be in the same or a different zone. In this case the following shall apply:
a) the mode of operation shall be configurable at access level 3 for at least individual zones;
b) the first alarm state shall be indicated by means of:
 an audible indication as in 12.10 which may be the same as that in the fire alarm condition or fault
warning condition;
 a visible indication of the affected zone, which may be the same as that for indication of zone in
alarm as in 7.3. The General Fire Alarm Indicator shall not be illuminated;
c) it shall be possible to manually cancel the first alarm state at access level 2. This may be done with the
same control as is used for reset from the fire alarm condition or fault warning condition;
d) the CIE may have provision to automatically cancel the first alarm state after a time interval which shall
not be less than 5 min;
e) if the mode of operation is configured to accept a confirmation alarm signal from the same fire detector,
this shall not be inhibited for more than 4 min following the receipt of the first alarm signal.
7.12.3 Type C dependency (option with requirement)
Following the receipt of a fire alarm signal from a fire detector or a manual call point, the CIE shall enter the
fire alarm condition, but may have provision to inhibit the activation of outputs until a second alarm signal is
received from another fire detector or manual call point, which may be in the same or another zone. In this
case it shall be possible to configure the mode of operation at access level 3 to apply individually to each of
the following (where provided):
 output to fire alarm devices (item C of Figure 1 of EN 54-1:1996), as in 7.8,
 output to fire alarm routing equipment (item E of Figure 1 of EN 54-1:1996), as in 7.9,

energised the data shall be retained for at least 14 days.
8 Fault warning condition (see also Annex F)
Delete 8.1.2 and substitute
8.1.2 The CIE shall be capable of simultaneously recognising all of the faults specified in 8.2 and (if
provided) in 8.3, with the exception that the recognition of a fault in a given zone or function may be prevented
by one or more of the following:
a) the presence of fire alarm signals from the same zone,
b) the disablement of the corresponding zone or function,
c) the testing of the corresponding zone or function,
d) the activation of the output to a transmission path which is exclusively used to transmit signals to:
 fire alarm devices (item C of Figure 1 of EN 54-1:1996) or,
 fire alarm routing equipment (item E of Figure 1 of EN 54-1:1996) or,
