LON-WA4/B

Communication interface for exchanging variables via LonWorks

Functional modules designed for the monitoring of motorised fire dampers

  • Easy integration into higher level systems due to standard network variables (SNVT)
  • Programming is based on LonMark functional profile 110.01, 'Fire and Smoke Damper Actuator'
  • Direct communication between modules (decentralised intelligence)
  • High transmission reliability and data integrity
  • Network can easily be expanded (free topology)

Functional description

LON-WA4/B is used to control up to four fire dampers with one limit switch or two fire dampers with two limit switches each.

The output variables of type SNVT_switch and SNVT_hvac_emerg signal the current damper blade position. They are sent after the input condition has changed, at the end of the heartbeat time (nciDiHeartbeat), and after a module reset (1s + node number [ms]).

If LON-WA4/B is used, the heartbeat function should be activated (for safety reasons).

If input variable nviDoHeartbeat has been set (100.1 1), then the output variables nvoDiValue[0...3] and nvoDiAllValues are updated and sent in intervals set with configuration parameter nciDiHeartbeat. This ensures that the transmission path is being monitored.

If there is a chain of modules (and hence fire dampers), the FireChain variables can transmit a signal from the first to the last.

Variable nciInvertDiValue is used as a configuration parameter to invert the output values. The debounce time for digital inputs can be configures with the nciDiDebounce variable.
