Just picked this up and love it. You plug it into the 24volt plug on the apex and you can have it go on for any emergency issues. The main reason i went with this is that overnight my phone is on Silent and I cant get notified if my Apex alarm goes on for real emergencies. So now I can set any real emergencies to sound this and it wont turn off until I shut the switch off or fix the issue. I have the display unit and tried the audible alarm Apex has but they are not great and do not stay on continuous. Not sure why apex does not have something like this.
Im sure my wife wont like it if this wakes everyone up, but I would rather not wake up to a problem like I did the other day.
