It has been a few years since I've been in the fire protection business but the system probably has not changed much, of course check it out first. If the alarm has an updated tag by a company or authority then they are probably already on a routine schedule for testing and the HI should probably leave it alone. If the alarms are monitored but no tag or other information indicates a routine maintenance schedule you can test the system but first the owner must call the people who monitor the alarms (ADT, ASI, Vanguard, Fire Department, etc.), give them a code, tell them testing will occur soon, ignore the alarm, and the owner must call back when testing is completed.
The same basic things apply with sprinkler systems. If it is a "wet pipe" system it might trigger a flow switch and send an alarm. If it is a "dry pipe" system it might trigger a pressure switch and send an alarm, and then the "dry pipe" has to be reset. Both of these types of systems will trigger an available alarm if the test valve is opened. Beware! These can resemble a hose bib even though they should be an actual sprinkler head mounted at the end of a water pipe.
Testing any of this stuff other than smoke alarms is probably beyond HI responsibilities but thought you might be interested, and if you accidently send out an alarm you will soon have a yard full of red or yellow trucks with flashing lights. Been there, done that.
