You have been trained in the operation of fire alarm systems, your customers have not... at least not to your extent.
But your customers still want to know, at least as far as how it affects them, how the fire alarm system works. The more they know, the better they can do their job (usually).
In Toastmasters International, an organization that teaches public speaking, we are taught to increase the listener's knowledge and understanding. If those listening can have their understanding increased even a little, they are better off.
It isn't expected that anyone can make a nuclear power plant engineer from a school custodian. However, if they're interested, you still can leave your customers with an improved understanding of the fire alarm system. Then they, in turn, when you aren't there, can do a better job when dealing with the system.
Of course, this advice has to be balanced with the knowledge that some people will use the information you give them and wreak havoc with the fire alarm system through partial knowledge and the desire to "do-it-themselves."
Just watch out for these people and give whatever understanding you can give of the fire alarm system without giving away the ability to "wreak havoc."
