Fire and Gas system for Boiler Protection

Hi, for protection of an industrial boiler (150T/H) at gas liquefaction company we need Fire and gas system, but the number of detectors is reduced (20 to 30 detectors), so I want to know if we need an independent controller to manage system or we can connect the detectors to another system, for example, BMS (Boiler manager System)?

It purely depends on your plant philosophy.

You can do this with your existing BMS PLC by adding extra IO modules or utilizing existing spares.

Or you can use a individual stand alone controller and interface with your BMS to initiate a trip/alarms.


If you go with your BMS PLC then you have to choose conventional based fire and gas detectors like 4 to 20mA output or simple NO or NC contacts as outpput.

If you go with stand-alone controller then you can choose either conventional type or address type fire and gas detectors, depends on your budget. in my personal view, you don’t need a addressable type for few detectors.
