System test 1

[@aidanthetoiletelevatorfire7554]

Love the good ol' mechanical horns! That advance looked like it was struggling on March Time and Code 3. And yes I like the 4903-9215/9217/9219 electromechanical horn strobes better than the 4903-9236/9237/9238 electronic horn strobes. Of course we all know that mechanical horns are better than the SpectrAlert Advance. Those electronic 4903s I like more than the SpectrAlert Advance.

You have to set the jumper on the advance to continuous or else it does that cursed sounding code 3
