VT408 / Extension unit (legacy)
Product page: VT408 / Sensor extension unit
Physical description
Module VT408 is designed to expand the number of analog sensors connected to monitoring systems.
1. "A1..A8" - 8 RJ12 analog sensor inputs with auto-sensing.
2. "Power" - for connection of external power supply 12V. Internal input "+".
3. "TR" - is the nearest switch to CAN inputs. This switch should be turned "ON" on the last sensor in the CAN chain. The last sensor in the long chain with a length of more than 10 meters, the terminator should be in "OFF" position.
"FR" - the memory switch, is necessary for reprogramming the module (the switch remote from the CAN connectors).
Do not use the DIP switch "FR" labeled "1", it should always be OFF. If this switch is turned ON, the module will turn off. This switch is only needed for programming purposes
4. "CAN1 CAN2" - two equivalent digital connectors RJ12 for the connection to the master module, CAN sensors, or CAN extensions on a CAN bus, with auto-sensing.
5. LEDs: "RUN" - indicates appliance connection status to the main module, "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 a monitoring unit, however, 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.
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.
