Edit: never mind, I guess you're talking about something else.
Nope you're right- we are indeed talking about the "no child left behind" alarm (the one that comes installed from the factory on C2's). Here's the problem- they want to disable just the alarm feature (buzzing, horns, etc.) but still leave everything else operational (overhead lights, light up sign, etc) for a training bus that (temporarily anyways) does not carry any kids. In reaching out to Thomas/Freightliner, they said you can't just disable it by cutting a wire or pulling a fuse. The multiplexer needs to be reprogrammed.
On another note, we're being asked to install 3rd party/aftermarket child safety alarms on buses that do not come with this feature from the factory. The Child Checkmate A-1 is the model. Anyhow, this requires wiring up to the horn relay, overhead lights, buzzers for the emergency doors, 12v, and ground. Working on the same bus (different year, no alarm from factory), the components are a real chore to access... and we're talking 100+ buses that need this install. For the overhead lights and horn, the side compartment next to the driver needs to be disassembled and probed to find the right individual wire. For the horn, the steering column needs to be disassembled to wire into the horn wire. For the buzzers, I haven't even been able to find the actual buzers yet. It seems like there's multiple hidden throughout.
Just thinking, there has to be a better way to install these things. Of course the video/documentation for the product show the install on an old bluebird... everything easily accessible.
Just wondering if anybody has any suggestions for this, or has a better way to access the wiring components from either a fuse box or relay or something. As it stands, one of these alarm installs is pretty much a full day's amount of work.
