Installation and Operating Manual
Bosch Security Systems
Alarm Inputs
The VideoJet X20 has four alarm inputs on the orange terminal block (see
Section 8.8 Terminal
Block, page 115
). The alarm inputs are used to connect to external alarm devices such as door
contacts or sensors. With the appropriate configuration, an alarm sensor can automatically
connect the VideoJet X20 to a remote location, for example.
A zero potential closing contact or switch can be used as the actuator.
X
Connect the lines to the appropriate terminals on the orange terminal block (
IN1
to
IN4
)
and check that the connection is secure.
Relay Outputs
The VideoJet X20 has four relay outputs for switching external units such as lamps or alarm
sirens. You can operate these relay outputs manually while there is an active connection to
the VideoJet X20. The outputs can also be configured to automatically activate sirens or other
alarm units in response to an alarm signal. The relay outputs are also located on the orange
terminal block (see
Section 8.8 Terminal Block, page 115
).
X
Connect the lines to the appropriate terminals on the orange terminal block (
R1
to
R4
)
and check that the connection is secure.
Remote Indication of the Connection Status
When the VideoJet X20 is connected to a video, the
Connect
LED on the front panel of the
unit flashes. The LED also provides information on the operational state of the unit and signals
a unit defect (see
Section 8.4 LEDs, page 113
).
You can connect an additional two-color LED to the VideoJet X20 as a remote indicator. This
provides the same information as the integrated
Connect
LED. A remote indicator can be
useful if the VideoJet X20 is installed at a location that is difficult to access or see, for
example in a cable duct or on top of a mast. Just like the integrated LED, the remote indicator
LED should also light up red and green in order to avoid confusion.
Please comply with the following specifications and the connection diagram:
