Edwards 270-DPO Pull Station Glitch

So recently, I was running a camera test (to make sure the strobe was being picked up on camera) and testing my pull station, it did a weird thing and didn’t go into alarm properly. It just would sit, but when a pushed the switch back to normal operation, it went into alarm.

You can see the video of this happening here:

Anyone have any ideas why this happened, it was connected to a conventional panel. and it wasn’t silenced. The messing with the panel before pulling the alarm was to enable the horns, since I was silent testing circuits earlier.

Sounds like it’s most likely a glitch with the panel. Does this happen with any other pulls?

Also, what is the panel?

The switch could be going bad. What happens if you short the wires together? Does the zone go into alarm properly?

Yes, the zone did into alarm properly. I have since determined that the panel contacts weren’t tightened completely and that might of had something to do with it.

The panel was a Fire-Lite MP-24
