  • Application

Application

  • LON-WA1/FT3 is a functional module that has been specially developed for the monitoring of motorised fire dampers
  • Up to four motorised fire dampers can be controlled with a LON-WA1/FT3
  • Supply voltage: 230 V AC, 24 V AC/DC
  • The connections for the damper actuators are either designed for the respective supply voltage of volt-free
  • LON interface with FT5000 transceiver
  • A separate LON standard bus is used as a communication line
  • Standard network variables (SNTV) have been used for all functions such that LON-WA1/FT3 can be integrated flexibly and easily with higher level systems
  • Based on the LonMark specification 'Fire and Smoke Damper Actuator'
  • LonMark functional profile 110.01, 'Fire and Smoke Damper Actuator', has been used

Functional description

LON-WA1/FT3 can be used to control up to four fire dampers.

If less than four dampers are connected, the 4-pole terminal blocks must have a wire link between the respective 'OPEN position' terminals (E1, E3, E5, E7). This is to prevent an alarm for non-existing dampers.

Input variable ActuDrive is used to control the fire damper.

Output variable ActuPosn is used to signal the current damper blade position.

The following applies:

  • Normal = Fire damper is OPEN
  • Fire = Fire damper is CLOSED

When LON-WA1/FT3 is supplied with voltage, the connected dampers move into their respective normal position.

In case of an error, VDMA sheet 24200-1 (Automated fire protection and smoke extract systems) applies:

Safe positions

  • Fire damper = CLOSED

If LON-WA1/FT3 is used, the heartbeat function should be activated (for safety reasons).

Setting parameter MaxRcvTime for variable ActuDrive, and parameter MaxSendTime for variable ActuPosn, ensures that all LON-WA1/FT3 modules regularly send and receive information. This ensures that the transmission path is being monitored. In case of an error, the damper moves to a safe position, and an alarm is emitted.

Input variable FT_Test or the test push button of the modul can be used to initiate a functional test of the damper. This moves the dampers to the 'Fire Position' and back to the 'Normal' position (OPEN). The output variable FT_Test indicates whether a test is being carried out.

The module remains in the text condition for the entire TestHoldTime.

If ActuDrive switches to 'Fire' during a test, the test is automatically aborted.

If there is a chain of modules (and hence fire dampers), the FireChain variables can transmit a signal from the first to the last but will not release a damper. The FireChain relay in the LON-WA1/FT3 module receives a signal and can be used for consolidated alarms or to switch off systems.

The Pulse variables are used to check a LON network.

If the input variable is set, the LON-WA1/FT3 module will change the output variable after 1 second. If there is a chain of modules, a trigger pulse is generated which can be read out at the end of the chain after N × 1 seconds (N = number of LON-WA1/FT3 modules).
