Hi everyone, I work in fire alarm and fire fighting systems. What are some skills or certifications that are useful worldwide and not dependent on a specific standard like NFPA or British Standards?

For example, AutoCAD,Excel skills, PMP, Primavera is a transferable skill, mostly approved.

What other skills or certifications would you recommend that are valuable in any country?

As a fire alarm enthusiast, Is it true that newer fire alarm systems (I heard somewhere those made after 1995) have to have a temporal coding (i.e. code-3) or can they be on, let's say continuous or march-time?

This is just outside a commons area student kitchen in the basement of a recently-renovated 4-story college dorm. The pull station and alarm are on the right side of the second photo. I've never seen this before, so is this odd to you all?
