LED MEANINGS
Name Function
DL1
Flashing slowly:
no data transfer over BUS at the speed set using
the dip switch.
Flashing quickly:
data transfer over BUS in progress.
DL2
Off:
the peripheral is communicating correctly.
Very slow flashing:
(approx. 3 seconds) no data package on the
BUS.
DL3
On:
indicates that one of the Open Collector outputs is under
protection due to a short circuit.
The
24H
terminal needs the Tamper contact to be connected in
single balanced configuration.
A resistance of
1.8KΩ
, in series with the contact, is required.
The incoming RS485 bus (bus IN) is electrically isolated from
the rest of the card. As a result, the V- input terminal must only
be connected to the bus running towards the control panel.
ALARMS
SINGLE BALANCED
Do not connect the V- terminal for the incoming bus to
other V- terminals present, and do not use it as a reference
for outgoing power supply voltage values. This could
damage the devices used, or cause them to malfunction.
For standard-compliant installation, connect the earth terminal
to the system earth, passing through the power supply earth
connection using the yellow/green cable supplied with the device
housings.
To guarantee system certification, the power supply unit must be
positioned in boxes protected by an anti-opening switch, or in
the control panel housing. The 24h input must be connected to a
balanced line, and connected to a Vedo system input line.
This device can be used to isolate the system so that any faults
or sabotage events which occur downline do not affect the
entire system.
The device is equipped with a dual connection to the VEDO
system 485 BUS:
• the IN port (input)
• the OUT port (output)
The section of the system that you want to isolate from the rest
must be connected to the OUT port.
Isolator module on control panel bus series Vedo. Allows
protection against faults and sabotage.
MAIN FEATURES
Art. VEDOISO omplies with standards EN50131-1 and EN50131-3
3.14 BUS ATOR (VEDOISO)
In the event of V+ V- power supply shortage, the auto-reset fuse
intervenes. For the reset to take place correctly, the power supply
must be cut off for one minute.
