8.7.7.2 AB time 
 
The menu allows you to configure the maximum delay between A and B alarms. 
8.7.7.2.1 Intrusion AB time 
 
The maximum time (0 to 255 minutes) that the system allows for a second 
intrusion alarm to occur to report a confirmed alarm.  
If the second alarm happens within this time, it is reported as a confirmed alarm 
(B-alarm). When the AB time has expired, any next alarm is again an 
unconfirmed alarm (A-alarm). If the zone that created the initial A-alarm is still 
active, it is inhibited. 
8.7.7.2.2 Holdup AB time 
 
The maximum time (8 to 20 hours) that the system allows for a second holdup 
alarm to occur to report a confirmed alarm.  
See also “8.7.7.2.1 Intrusion AB time” above. 
8.7.7.3 System confirm 
 
The System confirmation option defines if the AB alarm confirmation works in 
separate areas only, or if it allows for system-wide validity. If this option is set to 
Yes, an A-alarm in one area can be confirmed by a B-alarm in another area. 
Otherwise, the A-alarm can only be confirmed by a B-alarm in the same area. 
8.7.7.4 EE confirm 
 
The EE confirmation option configures the AB alarm confirmation during entry 
time. 
If the option is set to Yes, alarm confirmation is suspended during entry time. If 
no B-alarm was present, all alarms during the entry time are A-alarms. When the 
entry time has expired, alarm confirmation is enabled. However: entry/exit and 
access zones cannot generate B-alarms. 
If this option is set to No, the start of the entry timer disables any alarm 
confirmation until the area is set again.
