Operation

Alarm functions

Several situations can activate an alarm:
❚ Camera failure
❚ Activation of an external alarm source
(e.g. due to door contact)
The multiplexer can react to an alarm situation in the
following ways:
❚ The corresponding camera button flashes
❚ A flashing red alarm button
❚ One or more alarm messages superimposed on-
screen
❚ An alarm signal from the built-in buzzer
❚ Activation of other devices
(e.g. a video recorder or siren)
The details depend on how the system has been
programmed.
Image sequence
The sequence of displayed images may change in the
event of an alarm. The system can be programmed to
display – for example – only the images from the
camera involved in the alarm activation. In the event of
an alarm, pay particular attention to the superimposed
on-screen camera details.
If the HOLD function is active in the event of an alarm,
the monitor image remains unchanged and the HOLD
button flashes. You can activate and disable the
HOLD function as required. You can also program the
multiplexer to block deactivation of the HOLD func-
tion.
• Press the HOLD button to activate this function.
The button will light up.
• Press the HOLD button again to disable the
function. The button will not light up or flash.
Alarm information
Whenever an alarm is activated, additional related
information is normally displayed on-screen. This infor-
mation provides details of the camera involved. The
texts that can appear superimposed are as follows:
