Fire Alarm -- Maintenance

You have been trained in the operation of fire alarm systems, your customers have not... at least not to your extent.
Use language that can be understood by your customers - maintenance personnel or management. Instead of AFA say smoke detector, instead of NAC say Horn or Strobe, Instead of...

When Talking to Customers, Shouldn't Their Language Be Used?

By Douglas Krantz

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."

Electrical Flow


On this website, most references to electrical flow are to the movement of electrons.

Here, electron movement is generally used because it is the electrons that are actually moving. To explain the effects of magnetic forces, the movement of electrons is best.

Conventional current flow, positive charges that appear to be moving in the circuit, will be specified when it is used. The positive electrical forces are not actually moving -- as the electrons are coming and going on an atom, the electrical forces are just loosing or gaining strength. The forces appear to be moving from one atom to the next, but the percieved movement is actually just a result of electron movement. This perceived movement is traveling at a consistent speed, usually around two-thirds the speed of light. To explain the effects of electrostatic forces, the movement of positive charges (conventional current) is best.
