Extraction control for collective garages
Using the WK0400 module the extract for a garage can be controlled. It has 6 inputs, which are used for fire alarms and CO and 4 relay outputs 16A, to control the fans.
If no alarms, the outputs take turns running the fans alternately.
In alarm situation, all fans operate simultaneously until it ceases to be alarm.
Alarms are voltage-free and outputs are relay 16A, therefore, only a winkhel WK0400 module is necessary. It is powered between 120VAC and 370VAC and it is delivered in a housing for DIN rail or electric box.
Uniting all modules throught RS485 bus, it is possible to monitor the status of alarms and fans from a PC as a SCADA.
