Acknowledging Alarms
System cameras may be associated with alarm
contacts connected to key security points under
camera view. If an alarm is activated, the camera
scene associated with the alarm appears on a
system monitor or monitors that are armed for alarm
display. When the alarm camera scene appears on
the monitor screen, the word “ALARM” appears on
the monitor’s on-screen status line. If an alarm title
has been programmed, the alarm title also appears
in the alarm title area.
Some system monitors are armed for automatic or
delayed automatic clearance. Monitors armed for
manual clearance (acknowledgment) can be cleared
from a keyboard controller using the ACK key
located to the left of the joystick.
