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)
APPLICATION
Application
IO module with 4 digital inputs, used to capture the status of volt-free switches
Due to additional link options and alarm signalling particularly suitable for
monitoring fire dampers with electric limit switches
TECHNICAL INFORMATION
FUNCTION
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.
