Re: Alarm receiver simulator software

[Robert L Bass <sales@xxxxxxxxxxxxxxxxxxxxx>]

You will need to generate the handshake and kiss-off tones that
the receiver sends.  Without those the DACT will keep trying
until it goes into a communication trouble mode.

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.
