TRBO radios, and emergency alerting via panic button help?

[ElroyJetson]

I'm almost totally uneducated about MotoTRBO radios. Just getting that out of the way first.

I've been given the task of trying to make this idea work for a customer:

He wants a panic button system. Press the hidden button, a radio sends a silent alert to the security group's radio channel.

This is one of those fairly large sized quasi-religious "churches" that the local crowd of people who have a history of making
very questionable life choices tends to gather at. You know the type. There's one (or more) in every city. They NEED security
teams, because of the quality of their congregation.

When the button is pushed, the radio sends ID signals, and the ID numbers are known to the security guys so they know which
panic button location is calling for help.

I've implemented these before, in analog radios.

This time, they want to do it with MotoTRBO. Their selected panic button radio is the CM200D. And they want to do it on a digital
channel. Don't ask me why.

The idea is to hook up the panic button to the 20 pin accessory connector on the back of the radio. It was easy enough to find the pinout,
and I have the connectors and pins to wire that up.

I'm looking for clues and suggestions on how to program the radio to implement this feature.

If by chance it can't be done in TRBO mode, we'll fall back to an analog channel and make it work there. Still could use some guidance on
how to configure the accessory port in software. I've spent a fair amount of time exploring various configuration options and haven't been
able to yet make it transmit ANYTHING via any rear port connections I've yet tried.


Any help on this would be appreciated.

Not sure on the specifics of doing it with a CM200D, but I've done it with some Kenwood Viking mobiles. A simple push button to an MP3 board that has a pre-recorded message that then gets sent out over the air. The push button activates the board, which then has an output that you can use to key the radio.

You are on the right track, But you also need to set the GPIO/Telemetry functionality in the Configuration/Code plug.

Also, not sure the CM200D is the right subscriber, you might be better off with an XPR-5000 series subscriber as the interface.

 

[ElroyJetson]

Customer already has the equipment and wants to try to make it work. I have to attempt that and exhaust the possibilities before they'll go with something more suitable. I get to jump through that hoop. Yay.

 

[Firebuff880]

Since the manual shows GPIO pins on the connector I am guessing (do not have a code plug for this) that you can setup the Telemety data to do what you want on the source radio. Then you need to figure out who you are going to receive and process the Telemetry IO..

Does the security team have display model radios to view the RID of the unit seeking help? If so you could try mapping the P1 or P2 button as Emergency ON/OFF. The CM200d is pretty feature limited so I'm not sure how well it will work. You could also try doing CQ2 or a call alert of some sort.

To me it sounds like the CM200 would only be used for transmitting an emergency out. Then I guess portables would receive it and show what unit fired off. No connection to the GPIOs. Telemetry not available in the CM line.

Looking at codeplugs for CM200 and CM300 the only option for emergency is analog and MDC. You would have to upgrade your model to use digital.

 

[ElroyJetson]

That's it exactly. The only function of the CM200 is as an emergency alarm transmitter via external alarm button. It won't even be used to receive calls. I think it's kind of a strange application for a mobile radio but there it is.
The most advanced feature that will be used is multiple channel selections, each has a unique ID code, so the device can be used at one of several locations. Simply select the appropriate channel and put it to work.

 

[ramal121]

Well there's another oops. IDs are assigned globally to the radio, not on a per channel basis. You can only change with CPS.

 

[ElroyJetson]

Well, we'll accept that. The idea of having multiple IDs for various locations was a stretch goal, not the primary one.
