If the panel calls out and connects to a standard modem does it know that
it's not connecting to an Alarm Receiver at a Central Station?
Is there a way to run a terminal program in host mode and have the panel
transmit it's alarm to it?
I have searched the Internet and found a serial converter that converts from
SIA to ASCII. Would this work ?
Thanks

Also note that most DACTs need to see constant DC voltage from
the phone line emulator or they will go into a trouble mode.
Typical US telco lines run at ~48-51 Volts DC. The DACT might
tolerate a lower voltage though.
If this project is to be implemented on a working fire alarm
system there are UL and fire alarm code considerations which you
should probably discuss with your local AHJ.

The second is the one made by Osborne Hoffman (GE). They emulate the

There are limitations to the use of these software packages so do not
depend on them entirely.
Once you get these programs running the modem emulates a receiver and
gives the corresponding handshakes and kiss-off signals. The panel
wouldn't know the difference. I don't know of any Silent Knight
receiver emulators. Why does it have to be Silent Knight?
Any way, good luck.

I need a software program that can run in the background and handle the
modem translations.
I will be using the 5540 Silent Knight software and would like to hook a
standard modem to the panel.
I need some way of having the application answer the call and send the ack
tone sequence then wait for the panel to send the alarm.
I'm not sure if I need the kiss-off tone or not.
If I can get the panel to talk to the modem I should be able to make this
work.
If you have any ideas please share.
Thanks

The Alarm Receiver in Asterisk only does the Contact Id Format, if that
will suffice for you. You would then need a FXO (Foreign Exchange
Office) device to connect to a telephone line or a FXS (Foreign Exchange
Station)to connect to a phone set or panel etc. By far the easiest to
use would be the IAXY (FXS) from digium.com. You should be able to
connect your panel directly to it.
