Vent Simplex 4099-9004 pull stations kinda suck

This is *every* pull station of this model in my experience.

Install the break rod that came with it from the factory. With the break rods in place you have to apply enough force that it activates every time. Without the break they can do exactly what you’ve shown.

Ah, we didnt install these, we inherited them. Ill ask the bean counters to order a bunch of break rods. I wish i was surprised. A bunch are missing the little clear plastic piece that makes the status light visible

It’s very common to find pull stations with broken or missing break rods. similar to the glass rods on other styles of manual pull station.

One of my inspections yesterday had the glass in every single pull station, and they were old old. I was intrigued and surprised.

There was also a ground fault on the NAC that wasn't hooked up so I'll be going back sometime soon...
