− 
Block – incoming alarms are displayed on a 
block (group) of monitors with which they 
are associated. The first incoming alarm is 
displayed on the first (lowest numbered) 
monitor of the block. The second alarm is 
displayed on the next lowest numbered 
monitor of the block, and so on. When all 
monitors in a given block are displaying 
alarm video signals, all subsequent alarms 
are either held in queue or sequenced until 
the displayed alarms are cleared depending 
on the monitor alarm queuing method. 
− 
Dual Hold – an incoming alarm is displayed 
and held on the first of the pair of monitors 
until cleared. All subsequent alarms are 
queued in order on the second monitor until 
the current held alarm is cleared from the 
first monitor. As alarms are cleared off the 
first monitor, the stacked alarms on the 
second monitor are then transferred to the 
first monitor. 
− 
Dual Sequence – an incoming alarm is 
displayed and held on the first of the pair of 
monitors until cleared. All subsequent 
alarms are queued in order on the second 
monitor until the current held alarm is 
cleared from the first monitor. As alarms are 
cleared off the first monitor, the sequenced 
alarms on the second monitor are 
transferred to the first monitor. 
− 
Disarmed – The monitor does not receive 
alarms. 
Note: For information on defining the other fields 
in the Alarms – Monitors screen, see Adding

number of video loss detection modules installed 
and the range of cameras being monitored.
