Connection with the Alarm
Sensors

Connect the sensor switches to the unit's alarm port, as
shown in the example.

Notes:

• Alarm inputs that are simultaneous or with very short

intervals will be ignored.
Allow for at least 100 ms interval from one alarm input to
the next.

• Confirm the alarm sensor type (N.O. or N.C.) and con-

figure the system through SETUP MENU (OSD) or WJ-
SX150A Administrator Console.
The factory setting is N.O.

N.O.:

Normally Open alarm contact

N.C.:

Normally Closed alarm contact

• Alarm pins assigned as the time adjusting (TIME) termi-

nals cannot be used as alarm input terminals.

•

The specification of Recover Input:

5 V DC / 0 V (low-

active)
Recover Input, which resets alarm signals, is Pin No. 13
of the ALARM port. To reset alarm signals, contact GND
and Recover Input.
When you connect Digital Disk Recorder WJ-HD100
Series to the matrix switcher, set the recorder's alarm
polarity to Open-collector low by setting the MODE
switch #6 to off.

Connection with the System
Controllers

Connect the system controller to the DATA 1 to 4 port at the
unit's rear panel with the modular cable.

• Connect them in home run.
• In the factory default setting, the DATA 4 port is a

PS·Data terminal. To connect a terminal-mode system
