Program Z900 to call my phone
#1

How can one program the Airtech/ADT Z900 to call one's own phone or pager?
Since the phone number can be up to 15 digits, can a pause and code number be sent to a pager or phone?
Is there a way to get the sequence tones which the alarm received station will receive and send so as to build one's own home monitoring system using a computer and modem?

You will get little joy trying to do this with this panel. It predates the prevalence of pagers, so only has reciever formats to work with. All require a "handshake" and "kiss-off" tone to prevent the panel from going into trouble for failure to communicate. There is no practical workaround.
I know that alarm receiver cards can be purchased. I don't know the details of alarm receiver formats, beyond the frequencies that the most common use for handshake and data. I think that it's pretty much straight ascii data. They are the equivalent of a 10 to 50 baud modem.

Comm Failure
Being a electronic engineer this does sound like a nice challenge. It may be time to break out the protocol analyzers and see what it does. If there is a "comm Failure" will the unit still attempt to call the next time there is a problem?
I can always use the caller ID to tell me when and if it calls. Other than the periodic call to attempt to communicate, I don't expect a call unless there is a problem. I can program the reasons it calls, so I can only expect a break-in or fire and not loss of AC, low battery, etc.
Thanks for the information.

Yes, it will keep trying to call. It will also produce a trouble alert sound at the keypad. If you get a copy of the installation manual, it will tell you what frequencies that the different transmission formats use for handshake and data transmission. It's all standard modem tones, as far as I know. The manual even gives you a breakdown of how the data is grouped as it's transmitted.

Installer Code
I received the Safewatch Plus unit, but I was not able to get the installer code to work as described. I would enter 96321 or use the 3+9 on power up and the unit would only appear to enter the installer mode on the second attempt to enter the 96321 code (all LED's flashing). Using the default code of 254 would not reload the unit. According to the manual, one is to ener "1*" after 254#, and the Zone 1 LED was to turn on. This unit did not and would cause the LEDs to start flashing after entering 254#.
The actual unit is very much like the layout shown for the Airtech Z900 Installer manual except the micro processor changed from the DIP to a quad flatpack (TI TMS70C02FNL). If they changed the processor, maybe they changed the codes.
Any suggestions on how to restet the unit to default and get a new list of codes? The 3+9 after power on does not appear to work at all.

Ok adt's version all the addresses are moved around to prevent what you are trying to do. there are actually only 197 total addresses for a complete default go into programming and enter 180# 1 but caution if this is the oldest version (not sure of the ver. #) it will be programmed to only enter into programming after contacting a receiver most of them will enter after exhausting the dialing attempts(10) at default wait and it should enter programming but like I said most addresses are completely differant from the z 900 manual

Is there a delay before entering installer mode?
From you response, there must be a delay after entering 96321 before entering installer mode, this might explain why it did not appear to work correctly.
The marking on the unit label shows:
Safewatch Plus
1A910-50 RV. AP2894Z
Is this the older version requiring contact to the receiver? Can you tell if this version should follow the Z900 codes or ADT's?

I dont have one to refer to. But the a910 in the number is the adt part #. Like I said if you wait it should eventually go into programming. There are alot of installs where there are not phone lines at time of install so it wasn't cost effective to limit completion until there was. then if you want to default do as above. but again most of the addresses in the safewatch are differant than the z900. most of the lower ones, zoning and such are the same

As a side thought it might be easiest to pick up a voice dialer that would trip off the siren output and call your phone. it would'nt give seperate signals for burg, fire and others. But at least it would audiblely tell you there was an emergency at your home. Then you could disable the built in communications altogether. They do run about $100 so it might just be as cost effective to pick up a package deal from the multitudes on the popular auction sites. all the panels from the last 5 or so years have pager functions mostly.

I didn't understand your reply. I found a site which offers the manual for a reasonable fee. Or, the other choice is to change the program chip to a Z900. Assuming the A910 can be programmed to call and interface another security monitoring service, this should be all I will need. Do you know if the A910 will allow such changes?

I don't have that one. They are uncommon in my area, and the few that I encounter, i've been able to work via a moose Z900 install manual. ADT keeps it's manuals pretty close to the chest. If you get one, it's usually dumb luck.

Dumb luck is how i got mine. found it in a panel on a takeover. As for sending one electronically I don't know the legal ramifications to that and adt is very protective of their copyrights. So I respectfully decline. Glad to help with any specific questions on addresses you ask though.

I respect your position on the manual. Best to be safe than sorry.
Regretfully, I played with the program on the A910 to see if I could discern any of the recognizable locations such as the phone number or Installer 96321 code. Things went ok until I got around the 200 series address and I must have wipped out the Installer code as it not longer works. Neither does the 9+3 within 60 seconds of power up.
Is there another way to force into the Installer programming mode or force the reload of default settings?
If I can't do this this I will go the route to purchase the new Z900 program chip and EEPROM. If this works then I should have more flexibility in how I configure the unit.

You will have to forgive me, but I've seen a lot of people waste money on outdated hardware from auction vendors. In general, if it's got one of the propriatory names like ADT, Brinks, First Alert, or the like, the hardware stands a good chance of being crippled in some way.
Modern hardware is not so expensive or hard to come by, and is more likely to be far more DIY friendly.
Ok, that's my rant. It's off my chest and out of my system.

I wouldn't consider stating the facts a rant. Especially in todays market place where you can pretty much replace a panel and 2 ketpads for around $200 the only reason I can see to go that route is they are a little more surge tolerant

There's no software method to do this. It means changing the eprom that holds the system core program. Since this system has been out of production for over a decade, short of a very lucky find on an auction site, start over with something modern.
