[EN54 section 7.12 Co-incidence detection (option with requirements)
Following the receipt of a signal from a fire detector, and until one or more
confirmatory signals are received from the same or other points, the CIE may
have provision to inhibit either the indication of the fire alarm condition, or
the operation of outputs to
- fire alarm devices (item C of figure 1 of EN 54-1), and/or;
- fire alarm routing equipment (item E of figure 1 of EN 54-1), and/or;
- fire protection equipment (item G of figure 1 of EN 54-1) .
In these cases at least the following shall apply:
a) it shall be possible to select the feature at access level 3 for individual
zones;
b) the inhibition of one output signal shall not affect the actioning of other
outputs.]
[EN54 section 7.11, Delays to outputs (option with requirements - see also 9.4.2.c) and
annex E)
The control and indicating may have provision to delay the actioning of outputs
to fire alarm devices (item C of figure 1 of EN 54-1) and/or to fire alarm routing
equipment (item E of figure 1 of EN 54-1). In these cases at least the following
shall apply:
a) the operation of delays to outputs to C shall be selectable at access
level 3 to apply to
- fire detectors, and/or;
- manual call points, and/or;
- signals from specific zones;
b) the operation of delays to outputs to E shall be selectable at access
level 3, to apply to
- fire detectors, and/or;
- signals from specific zones.
c) the delay times shall be configurable at access level 3, in increments not
exceeding 1 minute, up to a maximum of 10 minutes;
d) it shall be possible to override the delays and immediately action delayed
outputs by means of a manual operation at access level 1 and/or by means
of a signal from a manual call point;
e) the delay to one output signal shall not affect the actioning of other outputs.]
