Clean agent sequence of operations

Just had some questions, I'll lay it out how I used to do it but I'm being told to do it another way.

This is a fm200 system, and we have conflicting ways of doing the A/Vs

This is how I've done it for years.

1st alarm - Bell starts 2nd alarm - bell shuts off and pulsing horn starts Discharge - pulsing horn changes to steady horn and strobe turns on both inside and outside

This is how I've been told to do it

1st alarm bell and strobe 2nd alarm bell shuts off and pulsing horn starts Discharge pulsing horn changes to steady horn

So this one has the strobe going off constantly. Which I think the whole reason for the strobe is to tell people it's been discharged when they are coming in the room.

Any words would be great. Or a code reference. I don't have my book with me.
