CDM1250 Call Alert

[Vercomm]

Hey All,

Have a question regarding a CDM1250. I am setting up the external alarm (pin 4 on the rear of the radio). So far i can get the radio to set the alarm out from pin 4 using QCII, but i was really hoping to be able to do this with DTMF. Like i said, it works exactly the way i want using QCII, but i have been playing around with the DTMF call alert and cannot get it to work.

Anyone done this before or if i can be done? Perhaps i have something wrong in the codeplug.

Thanks!

Does the radio decode dtmf?

[Vercomm]

If I understand the help topic it list DTMF as a supported call alert, but maybe its not supported for the external alarm function.

Just wondering if anybody knows for sure.

Thanks

Vercomm,

In order for a CDM1250 to decode DTMF tones you have to install
AAHHLN4182 DTMF DECODE MOBILE OPTION BD $82.50 list.

You also need the option board install kit
RLN4823B OPTION BOARD INSTALL KIT $16.50 list.

Allen

Good morning,

I'm trying to figure out how to hook the radio up to an external alarm. Is there a basic schematic kicking around?

Thanks, Ken

what kind of external alarm, and how is it currently triggered?

Right now it's independent from the radio. There was an old radio in place and it was replaced last year with this one.

It's a box with a small board and relay that sets off an alarm bell. I would like to remove the board and use the relay hooked up to the radio.

Does that help?
