How we connect the fire system to the BMS system?

we connect the fire system ( alarms , tank level , air duct motorized damper ,...............)to the bms panel as status only not control ,,,,,,,,,,,,,the fire control is from fire alarm system..

For fire system there is fire alarm and control panel which is double check with BMS only connected for status

yes sure you can in zone control valve use butter fly valve with tamper switch can connected to bms
