This is a heads up for those operating the ACK ELT. I believe the correct orientation of the remote switch (If used horizontally) is the red button is on the left with the label stating EMG/ON and the black button on the right stating RESET/TEST. It's possible and easy to have the unit mounted upside down in the case so the black button is on the left labeled EMG/ON and the red button on the right labeled RESET/TEST. I have seen what appears to be close to a dozen units (Most on VAF) with the red button on the right and most I can read the label below as RESET/TEST. I'm not sure why ACK does not error proof this design. I have also seen pictures on panel builders web sites with the unit what appears to be mounted upside down. The insidious effect of this type of installation is if one would need to manually set off the ELT or to insure it is on you press the EMG/ON button (now the black button) and that effectively turns the unit off!!
If your ELT is mounted like the one below, I'm pretty sure it is incorrect. If you can't rotate it for some reason suggest adding labels that says RED-ON, BLACK-TEST.
Maybe someone with more experience than me can review but I'm sure the picture below the unit is installed incorrectly. It appears there are many out there like this.
