Crowcon Hydra addressable panels feature relays and can connect to external output and relay modules to control alarm devices or communicate with BMS control systems. BMS connectivity can also be achieved via the Modbus protocol. Gas levels and detector status are clearly displayed, and events such as alarms and faults are stored in non-volatile memory.

 

A 24Vdc power supply is fitted to supply power to the control panel as well as the gas detectors (depending on detector quantity. Back-up batteries may be fitted to ensure continued operation in the event of mains failure.
