XLS80e Fire Alarm Control Panels
Example 5
shows how to arrange inputs (in
this case zones) in priority:
i
An input from Zone 21 activates sounder
circuit 3, unless
ii
There is an input from Zone 22, in which
case the sounder circuit is turned off, unless
iii There is an input from Zone 23, in which
case the sounder circuit is turned on, unless
iv There is an input from Zone 24, in which
case the sounder circuit is turned off.
Thus Zone 24 has priority over Zone 23, which
in turn has priority over Zone 22, which in turn
has priority over Zone 21.
The logic statement is:
(Zone 21
AND
(
NOT
Zone 22))
OR
Zone 23)
AND
(
NOT
Zone 24) will activate sounder
circuit 3.
