We were asked to meet a sprinkler engineer at a unit within a shopping center to confirm that the fire alarm will do the following:

Notify the fire alarm panel if that sprinkler has been isolated via the isolation valve.

Notify the fire alarm panel if the sprinkler system has triggered.

If there was a fire then the fire alarm within the unit would trigger and that panel will notify the main center system that it is in fire. My question for you brain boxes is, is it a regulation that the sprinkler system has to notify the main panel of the two points above or is it enough that the fire alarm is already connected to the main sprinkler pump so it knows if there is water moving through the system. the reason for the query is the current system is not connected to each unit so it wouldn't know if they had been isolated or were spraying water.

There is no big book of regulations other than The Regulatory Reform (Fire Safety) Order 2005 which says, if necessary you should install a fire alarm. To achieve this to an acceptable standard, you need to use your acquired knowledge on fire safety, check out all the appropriate british standards and guides.

If this is a single building with multiple units with isolation valves for each unit then I can understand why the Responsible Person would need to be informed that an isolation valve has been operated but I would think it is very unlikely that any isolations valves would be accessible to unit staff, so it would be under the control of the RP. It is important that the main valve is monitored with senses to trigger the main fire alarm panel on the situation of the sprinkler. All this information should be contained in the fire risk assessment.
