■ Alarm Mode
When alarm (sensor) is accepted, the matrix switcher's
operation mode changes to the alarm mode. Then, the sys-
tem operates as follows:
• The camera image (alarm image) appears on the moni-
tor.
In the factory default setting, the alarm inputs 1 to 16
are associated with the same-numbered camera input
connectors. All the video output signals are sent to
Monitor 1. For example, when the alarm (sensor) con-
nected to the alarm input 1 becomes active, the camera
input connector 1’s image appears on Monitor 1.
• "ALARMnn" appears on the monitor.
(nn is the alarm number).
• Alarm output signals are supplied from Alarm Output 1
to 4 (#10, 11, 23 and 24) of the ALARM port (25-pin D-
sub connector) at the rear panel. Alarm Output 1 to 4 is
associated with MONITOR OUT 1 to 4. For example,
when an alarm input signal is activated on MONITOR
OUT 1, the unit supplies an alarm output signal from
Alarm Output 1.
• The monitor and alarm number will appear on the LED
display of system controllers. At the same time, the
alarm indicator will blink, the monitor indicator will light
up, and the camera indicator will go out.
There are two operation mode when more than one
alarm signal has been accepted by the unit that is
assigned to the same monitor.
• Sequence mode: An alarm operation is replaced by
another one after the dwell time ends.
• Hold mode: An initial alarm operation is continued
even after another alarm input is accepted.
Notes:
• The association of the alarm inputs with cameras and
monitors are changeable in SETUP MENU or WJ-
SX150A Administrator Console. (Refer to pp. 67 and 68/
p. 89.)
• Alarm input will be automatically reset in 30 seconds.
The auto-recovery time is configurable through SETUP
MENU or WJ-SX150A Administrator Console.
