Actions involving SND and FR output groups: unlinking them from zones
In the panel’s default configuration, a single detector or MCP alarm in any zone will trigger the activation of
SND and FR output groups.
If you require a more sophisticated action for these output groups (such as coincidence detection), unlink
the activation of SND and FR output groups from the alarms in the affected zones. Otherwise, they will
always activate with the first alarm. See section 0 for instruction on how to unlink SND and FR output groups
from some or all zones in the fire panel.
Figure 19: Advanced Programming Example
EN 54 Type “C” coincidence detection
The coincidence detection specified in EN 54 is a particular case of the advanced programming shown in
this section. In type “C” coincidence detection, the panel enters into alarm functional condition at the
reception of a first alarm. However, it does not activate its outputs until a pre-defined confirmatory signal is
received.
To program a type “C” coincidence detection, define an action for each of the SND and FR output groups
which requires two or more alarms to be processed prior to output activation.
Note that, as described in section 5.6.1.4, SND and/or FR output groups shall be unlinked from zones with
type C confirmation, or the first alarm will activate them.
The following action implements a generic “type C” coincidence detection.
S(000,DET,2)+S(000,MCP,2)+S(000,DET,1)xS(000,MCP,1) = P(SND,060,000)
That is, sounders will be triggered with 60 delay by the scenarios of:
-
2 detectors of any zone or
-
2 MCP in any zone or
-
One detector AND one MCP in any zone.
Please note that this setup requires sirens to unlink from zones. See section 5.6.1.4 for more information on
unlinking SND outputs from panel default operation.
