General Description
VDOT-DOP-AC240V-SCI Dual Output Module with Short Circuit
Isolator is an addressable dual output module that provides two dry
contacts. The contact rating is 4.8A at AC250V. The status of each dry
contact is controlled by a control panel.
General Operation
Normal Standby condition: The module receives polling from the control
panel at the regular interval. Polling LED (green) flashes.
Active condition: When receiving a control signal from the control panel,
the relay output is activated, and Output LED (red) illuminates.
Trouble condition: If an overcurrent occurs because SLC (Signaling Line
Circuit) is shorted, SCI LED (yellow) illuminates, and the module
communicates to the control panel the short status.
SCI (short circuit isolator) Function
The module has a built-in short circuit isolator. SCI circuit prevents
entire loop failure in the event of a short between L+ and L- on the loop.
If a short is detected between L+ and L-, the yellow LED is illuminated.
The line between Lin- and Lout- is disconnected automatically to isolate
the short circuit, and short circuit status is communicated to the control
panel. Upon removal of the short condition, the module will
automatically connect between Lin- and Lout- to restore the entire loop
to the normal standby status.

There is a danger of electric shock due to the presence of high voltage (AC250V).
Never touch the terminals while the power is on. Make sure to turn off the high
voltage AC power supply before commencing wiring work.

specified in the Specifications. It may cause a fire or damage to
equipment.
CAUTION
!
Do not disassemble, repair, or modify the products. It may cause a fire or
electric shock.

Before Installing
Disconnect power to the control panel before installing the module. If
the module is installed in an existing operational system, inform the
operators and local authorities that the system will be temporarily out
of service.
Mounting
Make sure to use a metal UL Listed electrical box (4’’ square) to mount
the module.
Secure the module to the box, as shown in Figure 3.
Note: The module must be mounted in a metal electrical box.

Address Setting
Use VDOT-AD2 Programmer for setting the address of the module prior
to installation. VDOT-DOP-AC240V-SCI has an address given at
random from factory. Connect the Programmer with the address setting
port to change the address to any of 1-254 (dec), with reference to the
instruction manual of VDOT-AD2 Programmer. The address can be set
regardless of whether power supply from the control panel is turned on
or off. During setting address, the module does not respond to the
control panel.
Set the address of module according to Job data.
Wiring
All wiring must conform to applicable local codes, ordinances, and
regulations.
Install module wiring in accordance with the appropriate wiring
diagrams.
Refer to the figure 4 for wiring.
Note: All wiring is power-limited and supervised.

Maintenance
Routine inspection: Ensure the module is secure and undamaged.
Operation Test
The purpose of the Operational Test is to confirm the product’s correct
operation.
1) When carrying out site testing of the product, the control panel
shall be set to “one-man-walk test mode” prior to the test.
2) Take any necessary precautions to limit the sounding of the alarm
sounders/bells and any fire service summoning device.
3) Operate an active signal from the control panel to activate the relay
output of the module, and confirm that the output LED (red)
illuminates.
Note: If the test cannot be carried out as terminal wiring is connected,
remove the wire connected to the dry contacts, and test between
terminal N/C1 , N/O1 and COM1
（N/C2, N/O2 and COM2）to check
the module. (When activated, the contact between N/C1 and COM1 (or
between N/C2 and COM2) is open, and the contact between N/O1 and
COM1 (or between N/O2 and COM2) is closed.)
4) After the module is brought into the active condition, reset the
module. It may be necessary to allow a short time to elapse before
the module is reset.

Do not connect cables in reverse polarity. Failure to connect the polarity
correctly could result in damage to the module and/or other equipment.
CAUTION
!
Use cable AWG12-22 for wiring. Do not connect different gauge cables
at one terminal in order to prevent loosening. Use a fork terminal for
crimping two cables.
CAUTION
!
There is a danger of electric shock due to the presence of high voltage (AC250V).
Never touch the terminals while the power is on. Make sure to turn off the high
voltage AC power supply before commencing wiring work.

Confirm that the module goes back to the initial status after the
module is reset. (In the normal status, the contact between N/C1
and COM1 (or between N/C2 and COM2) is closed, and the contact
between N/O1 and COM1 (or between N/O2 and COM2) is open.
5) Short between terminal Lin+ (Lout+) and Lin- (Lout-), and the SCI
LED (yellow) is illuminated. The short circuit isolator isolates the
devices connected after the short-circuited area, which makes
these devices have no response. Upon removal of the short
condition, the area is automatically connected to go back to the
normal standby status, and the SCI LED (yellow) turns off.
