XLS80e Fire Alarm Control Panels
Example 1
- Outputs in Zone 20 are activated
if: Inputs in Zone 3 or Zone 4 are activated, or
inputs in both Zone 1 and in Zone 5 are
activated (Zone co-incidence) but no inputs in
Zone 2 are activated.
The logic statement is:
(Zone 1
AND
(
NOT
Zone 2)
AND
Zone 5)
OR
Zone 3
OR
Zone 4 will activate Zone 20.
This example uses Transfer Flag 26.
Example 2
shows how to use two Transfer
flags so that ‘OR’ operations are performed
before ‘AND’ operations. Outputs in Zone 20
are activated if any input in Zones 1, 3 or 4 is
activated in co-incidence with any input in
Zone 5, but no inputs in Zone 2 are activated.
The logic statement is:
(Zone 1
OR
Zone 3
OR
Zone 4)
AND
(
NOT
Zone 2)
AND
Zone 5 will activate Zone 20.
Note:
This example uses Transfer Flags 26
and 28. The numbering of Transfer
Flags has no significance other than to
identify them.
Examples 3 and 4
show how to incorporate a
delay (delays cannot be included in the same
entry as the logical operation).
Example 3 is the same as Example 1 apart
from the delay in activating the output,
Zone 20.
In Example 4 the delay is on the input, for Zone
3 only.
