■ Resetting All the Alarm Inputs
You can reset all the alarm input signals at a time.
1. Select a monitor which displays "ALARM".
(Refer to the figure on p. 118.)
2. Press the ALM RESET button.
All the alarms will be reset.
Then, the LED display and indicators will return to the
state before the alarm input.
Note: You cannot reset the alarm input signals one by one.
■ Suspending All the Alarm Inputs
Use this function when you do not want to be disturbed by
an alarm input, for example, during the setup procedures.
1. To suspend all the alarm input signals, press the ALM
SUSPEND button.
The indicator beside the button will light up and "ALM
SUSPENDED" will appear on the monitor.
(Refer to the figure on p. 119.)
2. To cancel alarm suspension, do Step 1 again.
Notes:
• The alarm suspension is applied to all system units,
not to a selected one.
• An alarm which was input before the suspension
will continue to operate.
■ Alarm Mode
When alarm (sensor) is accepted, the matrix switcher's
operation mode changes into the alarm mode. Then, the
system 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.
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.
■ Operation during an Alarm Mode

• Resetting all the alarm inputs (ALM RESET)
• Suspending all the alarm inputs (ALM SUSPENDED)
