Another solution would be to give the alarms their own dedicated telephone lines.
If the panels must share lines with the PBX another approach would be to wire the panels in series with the Magix. That way, if a panel needs to report something, it can disconnect any active calls, re-seize the line and dial out. Each panel would need to be wired to a different line.
If it ain't broke, I haven't fixed it yet.

I need to clarify my last comment ![[purpleface]](/data/assets/smilies/purpleface.gif "[purpleface] [purpleface]")
.
With the Magix wired in series with the alarm panels, the POTs lines are first wired to the panels and then to the Magix. Under normal circumstances, the panels act like high tech bridging clips:
(Normal operation)
MAGIX-------A-L-A-R-M-P-A-N-E-L--------TELCO
(Emergency Operation)
MAGIX------//A-L-A-R-M-P-A-N-E-L-------TELCO
I hope this makes things a bit clearer.

And by all means, do NOT use analog extension ports for your Fire Panel. Doing so would likely violate a local or state building code.
More importantly though, there could be severe legal consequences if (God forbid) something was wrong with your PBX ports when the alarm panel needed that dialtone to notify the Fire Department.
As previously suggested, you can share any existing analog trunks that are used by the PBX for voice calls PROVIDED THAT you use an RJ-31X jack or similar wiring scheme.

When fire and police depts start paying for independent dial
tones to alarm panels...by all means go for it. Otherwise
alarm panels will share local lines and alarm service companies shoulds be the ones installing a dial tone at the RJ31x..so as to certify their operation.

We had a similar thing at my workplace. Telco brings in a VoIP pipe that we split off into PRI channels for PSTN access. I had a couple of analog ports in the Merlin set for this dedicated purpose. But the security company demanded independent copper wires coming in for each POTS line they hook into. At our extra expense of course. After a nice clean VoIP pipe coming in I had to drop back old-school ann punch down all of the cross connects. At an extra $23 a month per line :-(

Here's the thing. A fire could start at an electrical panel (or even your phone room) and render your PBX, IAD or multiplexor useless. Where does you dialtone come from then? And how long will said equipment stay up if the fire sprinklers are spraying water all over it at nearly two gallons a minute?
Now consider the alternative provider. Telco Points-Of-Presence are usually unmarked, windowless brick and steel buildings that are crowned with lightning arrestors. To get to the guts of the building, you usually have to pass through two handprint identifiers, armed guards and God know what else. The "carrier class equipment" that provides the dialtone is of a quality not available to the public. It has been also been carefully installed with backup upon backup. It would startle you the number of generators and battery stacks such building have. Indeed, the term and statistic "five nines reliability" or 99.999% refers to the availablity of their service.
But even with all that reliability, the Fire Marshall and panel STILL require two unique POTS lines. That's how serious building fires/emergency service response is taken. If you understand the consequnces of such a system failing, I don't get why anyone would quibble about $30 or $40 a month for peace of mind.
