Note
Because of the fast update rate of the colour units, if one camera is in alarm,
interleaved mode will result in real-time playback of the camera in alarm. In
general, on the colour units, interleaved recording will give very fast update
speeds of cameras in alarm even for multiple alarms. This is not the case for the
mono units, which do not have fast PVP recording at alarm speeds.
Alarm Indicators
There is an on-screen display of an A in each corresponding cameo of multi-screen
displays and ALM, on any full-screen displays relating to cameras in alarm. The
indications will be flashing.
An additional indication, in the form of an LED, is provided on the front panel, under
the ALARM key . The left hand LED will flash if any live alarm is active and has
not been cleared.
An internal buzzer can sound while any live alarm is active. This buzzer can be
silenced by pressing the ALARM key or if required, disabled.
Alarm Latching
There are three ways of latching alarms, which may be selected via the menu. These
are:
1) Latched until the operator cancels it (Latched).
2) Not latched (Transparent).
3) Latched for a pre-set time (Timed Out).
To set the type of latching, select Alarm Latch in the Alarms sub-menu. All the alarm
inputs are controlled by this single setting.
Latched Alarms
Alarms are latched as they become active. An alarm will stay active until the operator
acknowledges it by pressing the ALARM key . There is no time-out period.
When the operator acknowledges the alarm, it will be cleared, whether the alarm
input is still active or not.
Timed out alarms are latched for a pre-set time out period from the start of the alarm
becoming active. After expiry of the time out period, the alarm is automatically
cleared unless the alarm input is still active and then it will clear immediately after the
alarm input ceases. Alarms that cease and restart before the time out is complete,
will restart the time out period.. The time out period is programmable in the menu
system.
