The PRO-S is used as a damper unit in Lindab Fire System Pro. It works together with a master unit (PRO-M) where most of the setup of the PRO-S is made.
The damper unit has two analogue inputs, two digital inputs, one analogue output and two digital outputs. The in- and outputs are used for e.g damper control, smoke detector, temperature sensors and VAV. It communicates via Modbus. One terminal is used as +19 V DC supply voltage for a smoke detector.
There is an app available (Lindab ProLinkTM) for Android and iOS that can be used to identify the units and for setting a Modbus address for the unit. The app can also be used to upgrade the firmware. Get the app from App store (iPhone and iPad) or Google play (Android).
