Moved in and previous owner left no info on Ademco Lynx control panel. I would like to use but don't know Master code. How can I find out master code

Be sure you understand the difference between a master code and the technician code. A master code lets you program other codes (and do some other harmless stuff). The technician code lets you do anything in the panel. If no master code is known you will need to default the panel. Do that by turning off power and disconnecting the battery. Reconnect the battery or plug pack and within 10 seconds enter 971300 on the code pad. That will wipe the eeprom back to factory defaults, and reinstate user 1 as a master code with a value of 1234. Don't even think of doing any of this without an INSTALLER manual. (Not the same thing as the USER manual). Better still, get an alarm tech familiar with DAS or CADDX products to program it for you. Worth every penny. After that you can add/delete users with your own master code using the much simpler User manual. Any code can be set to be a master code (that is you can have more than one master code)

Resetting Your Installer Code
1. The installer code (IC) is the code that allows you to access the system programming. If you forget your IC, your alarm company probably won't give it to you. This is because they use the same IC for many installed units and keep it a heavy guarded secret. If your forget your IC code, you're going to have to reset it.

First locate and disconnect the transformer. This is a cube-shaped wall outlet, usually placed around the alarm control panel. Next, shut down the alarm system's power supply. You may have to unplug a battery if you have a secondary power source connected to the alarm system. Once the alarm is powered down, you will reconnect the transformer and the battery in that order.

The rest of resetting comes on the keypad. Within 30 seconds of powering up the alarm, go to your alarm key pad press down the * and # keys simultaneously until you see "20" displayed. At the same time, you should see "Installer Code." Enter your new installer code while the "20" is still on the screen. Your installer code will be four digits. The keypad will beep to acknowledge the new installer code. After the keypad beeps, press *99 to exit the program. To check if you have reset the code successfully, enter your new installer code and press 1 (off). The keypad will beep once if you have successfully changed your installer code. If it doesn't beep, repeat the process.
Resetting Your Master Code
2. The master code is usually only used by the home owner. Other users codes can also be set up, including manager, babysitter, gardener and housekeeper codes. The home owner will use the master code to set up these other codes. The master code is also the code you will use when you come home and need to deactivate the alarm before it goes off.

To reset your master code, type in your installer code, press 8, press 02 and then punch in your new master code. Press 1 to turn off the programming. Your keypad will beep when you successfully reset your master code. You can now activate and deactivate your alarm system as you please.

We need more information. The answer is different for different models and Ademco has dozens of models. Tell us the model of your control panel, usually on the inside of the panel cabinet door) and we can help you.

Go to your favorite search engine, Google or whatever, and use the phrase "Ademco Lynx Installation Manual". It has the instructions you need. You may have to look through 5 or 6 hits, but you can download the manual for free.

And please stop shouting. ;-)

First of all, what is the model number of your control panel? Setting a new master code is different for different models. The model is usually named on the diagram on the inside of the control panel cabinet.

1234 is the new master code, 4112 is the installer code to get into programming. If you defaulted the panel, all previous zone programming is lost as well as reporting methods and types for those zones. Basically it's set back to the way it came out of the box!

What type of panel is it? Do you have the manuals?
