condition). In order to switch between the different default levels, press ENT; the output

will immediately change its value.

●

Timing: The output time is the time that the output remains active (the active status

depends on the default level setting) when the CU processes an alarm condition. Press

ENT to display the menu shown in Figure 23. Press ENT again and the cursor will

underline the hour field. Press ENT again to save the Hour value and pass to the

minutes field, and finally to the seconds field. The maximum time allowed is 11h 59m

59s.

Partitions

Partition menus (Figure 24) are used to configure partitions which are logical groups of

zones. Each time a partition is activated by an activation code (see Section 5.6.9: Bus

modules), all associated zones are controlled by the CU to detect an alarm condition

(infraction). Alarm conditions in inactive partitions are ignored and not processed (even

when detected) by the CU.

Partitions are associated to zones both in input and in output. The input association is the

group of zones that will be removed from the control flow of the CU once this partition is

disabled by any activation code (normally when entering the protected area). The output

association is the group of zones controlled (and processed when an alarm condition is

detected) by the CU when leaving the protected area.
