Caddx NX8E ramblings:

[alarman]

I too am unhappy with the inability of the panel to stop beeping when
the power restores (when it's programmed to alert the customer through
the keypad), or when dial tone returns. Its disturbing to neighbors
in apartments/condos.

The keypad alert is especially annoying when people are sleeping and
the electric company is turning off/on/repairing the power lines, and
the customer has just gotten back into bed after entering his code to
silence the pad, and the power shuts off again. I stopped programming
keypad alert on power loss when the system is armed/disarmed!
However, I always program for power loss reports to the central
station, if the power is still off after a specific length of time.

Yup, if I decide to start using this panel, I'll be doing the same.

Sorry Mark, I'm not sure I understand your point. A "cludged" modem would
likely not be as "accurate" as a conventional tried and true modem
...........no........I guess I still don't understand your point

The reason why the baud rate panels use is so slow is because speed is not
as important as accuracy, at least that was the reason in the past when
almost everything was 4/2. Now with Contact ID and SIA sending signals in a
fraction of the time its just not worth it to the manufacturers to put in
actual modem chips when all they will save is maybe 1 or 2 seconds in
transmission time.

The only advantage to adding a real modem is for downloading purposes and
considering that less than 5% of alarm companies download panels its still
not worth it to the manufacturers when dealers often look at a price
difference of $1 to $2 per panel when deciding what to buy (which is stupid
but it happens a lot).

Ok, that makes sense now...thanks...

Both the older 8 switch and the newer 10 switch models work and put
out that initial carrier tone. Part # 07-00038 is the newer model. A
quirk of the 8 switch model is the L(x) command hadn't been invented
because there is a volume knob on the back so it must be set to N/A or
removed from init strings. The portion of the string that triggers the
tone output (for caddx) is the S10=255 section of the init string. A
lower value will not put out the tone but will let you hear call
progress until the panel answers. Personally, I just leave the sound
on then turn down the knob when it is irritating. I don't think caddx
makes that 1200 module any longer, either. I don't know of other ways
to speed up the communication. Normally, for an operational panel we
only have to make small changes then send the range or section instead
of the whole thing.

Well, the Hayes 1200 07-00038 came today. It works great with both DSC and
the new NX8E panel using the two call method. The NX8E doesn't answer in the
tone sniff mode however, so I need to play with it some more. I checked the
MI string, and it has S10=255.

Hmmmm I'd say it was dip switches then, and I've rarely had luck getting one
to work with DSC

BTW: The Ademco CIA2400 modem also works great for caddx but I never tested
the tone sniff part

It seems to work just fine with DSC, but I do get a "Modem not Responding"
error message after I disconnect. The next call goes through just fine. I
haven't looked at the dip switches yet.
