The EP1plus replaced the EP1. The EP1plus and has a more powerful processor (which we need for all the different regional specifications and logic that it has to accommodate). It also has more connections available to accommodate certain specifications (e.g. some regions require that a status light is visible on the dash, some require that doors, brake, parking brake are monitored, etc.).

@@bradboth2698 Ah. I know that the EP2 is the one with the extra features, such as the brake light, and the optional speaker.

@@212Elevators yes, EP2 has several more I/O available, integrates with other systems (e.g. your GPS system), integrates with speaker, motion sensor. EP2plus has more IO than the EP2, stronger processor and more memory (e.g. for more language options or voice prompts).

@@bradboth2698 Wait, I never heard of the EP2plus. Is this the one that can get you the voices like "Warning: Rear Door Open" and "Child Checkmate Is Now Deactivated"?

@@bradboth2698 Then I noticed the CM1 and CM3, which seems like part of the EP2 plus. And I'm also noticing some of the RVT's that light up.

Yes, good idea. We're going to start publishing a bunch of short 'Lab' videos like this one in November. We'll add this one to the list... we do have some support articles RE tones: childcheckmate.helpdocs.io/search/tones we'll add one in the next few months about voice prompts, too. Thanks!!

@@ChildCheckMateSystem Can you go inside a bus and show the speaker and let us hear what it says please all of the prompts that it says?

@@carwashslayer4235 yes, but it might be in our lab, not in the bus. we'll do this in November. Please keep in mind that we'll be posting generic advice: we have over 60 different software programs (for all the different state, provincial, county and company specs) so it might not sound exactly like your system.

Also, here's our premium support page (we've not officially launched it yet). childcheckmate.atlassian.net/servicedesk/customer/portals You can sign up and make this request there, then you'll be notified when it's in progress, completed and where to access it.

@@ChildCheckMateSystem OK will you have a speaker wired up?
