This unit is designed to provide visual and audible alarms for HVAC systems.
It is equipped with indicators and speakers to generate both visual and audible alarms. This ensures that failures or alerts from HVAC installations in less accessible places can be easily detected and addressed promptly.
The unit is controlled using the Modbus RTU communication protocol. Modbus RTU enables communication between the signalling unit and other devices in the HVAC system, such as sensors, controllers or a building management system (BMS).
It operates on a 24 VDC power supply and provides two connection options. It can be connected via the RJ45 socket, which is commonly used for Ethernet or Modbus communication and it can also be connected via terminal blocks. It also features 3 open collector outputs.
