The unit can be found on our official website at: VT408DIN / Sensor extension unit

Physical description

Module VT408DIN is designed to expand the number of analog sensors connected to monitoring systems.

 


1. "A1..A8" - x8 RJ11 6P4C analog sensor input ports with auto-sensing.

2. "Power" - for connection of external power supply 12V DC, 05A.

3. LEDs:

   3a. "RUN" - indicates appliance connection status to the main module,

   3b. "ERROR" - indicates appliance lost connection to the main module.

  • ERROR is lit continuously, RUN blinks - the unit has no connection with the monitoring unit.

  • ERROR is continuously lit, RUN repaid - extension unit communicates with monitoring unit, but it is not included in the monitoring system (not configured).

  • ERROR repaid, RUN lights up continuously - the extension unit is included in the work as part of a monitoring system.

4. "Terminator" - This switch should be turned "ON" on the last sensor/device in the CAN chain.

5. "CAN bus" - x2 equivalent digital RJ11 6P4C connectors for the connection to the master module.

Function

VT408DIN module is developed to expand the number of analog sensors connected to the monitoring system. The picture below illustrates the expansion example:

Mounting

DIN rail mounting

  1. There are DIN rail mounting hooks at the top and the bottom of the case. Pull them outwards.
  2. Press the enclosure against the DIN rail so that it fits behind the enclosure.
  3. Tap the hooks back in to snap to the DIN rail.

DIN rail unmounting

  1. Use a screwdriver and pull the x3 hooks on the enclosure outward.
  2. Pull the enclosure away from the DIN rail.

DIN rail extension, wall brackets are purchased separately.

Installation

Connect CAN input of the unit by RJ11 6P4C cable supplied to the CAN input of previous CAN unit or monitoring system. The red LED lights up. Match the TR bus terminators on the attached CAN units. CAN bus terminators TR (position 2 in VT450) should be in the ON state only at the end CAN units port and in Off states (1,2) for all intermediate units. One CAN bus can have not more than 8 CAN units, sensors and / or another CAN devices. 

Normally 12V 0.5A external power supply is connected to the jack labeled PWR (point 2 in the general scheme). But if the only VT408 unit is connected and the length of the cable from the monitoring unit to the VT408 does not exceed 10m allowed the extension unit operation without any external power supply. In all other cases the use of an external power supply is desirable.

Configuration

To connect CAN unit to the system, open interface and go  CAN Configuration  Select tab CAN.

Click "Configure" and wait. The system starts the CAN bus line survey, display the list of connected CAN units and sensors. On the CAN devices, the green LEDs lights up.

If you will go now to the "System tree", you will see there new CAN devices and/or new CAN sensors. Wait a little or renew tree.

If the survey is reset after click "Configure", it means that the line is not connected (bad cable and / or bad connectors) or not matched terminators on the bus. It is necessary to check and change the status of line or the TR terminations.

Analog sensors are connected to the A-1 ... A-8 analog inputs on the module, the definition of the sensors will occur automatically.

pic.1.1: FR is OFF, TR is ON.                    pic.1.2: FR is OFF, TR is OFF.

Indication

The VT408 expansion module has two RUN and ERROR LEDs that show the following states:

  • ERROR continuously lit, RUN flickers - the expansion module has no connection with the master module
  • ERROR is continuously lit, RUN is extinguished - the expansion module has communication with the master module, but is not included in the monitoring system (not configured)
  • ERROR is extinguished, RUN is continuously lit - the expansion module is included in the monitoring system

CAN setting

The extension module has a built-in element:

  • Power -  the element of relay
    This element, by designation, is identical to the Analog Power element of the monitoring module. It turns on or off the power of the analog sensors.
    The analog sensor power off for a few seconds is used to reset the alarm of the VT560 smoke detectors connected to the VT408 expansion module.
    Warning: when the analog sensors are powered off, all external sensors connected to the VT408 cease to function.


    The analog sensors connected to the VT408 are configured in the same way as the sensors connected to the monitoring module.
