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, or from a fire detector in the same
or a different zone. In this case, the first alarm state need not be indicated, and
the following shall apply:
the mode of operation shall be configurable at access level 3 for at least
individual zones;
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 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;
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;
the Control and Indicating Equipment (CIE) may have provision to
automatically cancel the first alarm state after a time interval which shall
not be less than 5 min;
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.
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 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
output to fire alarm routing equipment
output to fire protection equipment
