6.0 REMOTE ALARM MODULE AM1 OPERATION
The Remote Alarm Module AM1 is an interface for the
failure signal transmission between Hamworthy Trigon
devices and external applications. It is to be connected to
a the Hamworthy Trigon DeltaSol BS2 or M Solar
Controllers or Trigon WMZ Calorimeter via the VBus.
When the Remote Alarm Module AM1 is operational, the
LED will glow continuously to signal operational
readiness. If the LED does not glow, check the
connections to the device !
The Remote Alarm Module AM1 receives and processes
the Vbus data of the devices connected. In the case of a
failure signal, the integrated Flash-LED flashes and the
AM1 operates a potential-free relay.
The relay can be used to connect an additional signaling
device, or to connect to a building management system
(BMS).
