    Thanks. I'll try it. At the risk of sounding completely stupid, where do you find the system type? It says "Concord Express System" on the garage panel. This is probably an old unit. The house was built in '96.

SOURCE: Hi! Just had ADT install security system and

My understanding is that GE does not produce a wireless interior siren any longer. So if yo want to get a siren in the garage a wire will have to be run from the Simon 3 to the location in the garage where you would like to place the siren. PS ADT will not run wires to a detached garage. GL

I have a home security system Simon 3 that was at one point under service with ADT. It is no longer has service with ADT. I like that it was notifying when the doors were opened, but the battery low...


Try powering down the system completely and powering it up with the battery first, that's how I do it. If the alarm goes off again you can try entering 2580. Be careful doing that! If for some reason that system is still be monitored you could end up with the police at your door. It might be a good idea to call ADT and give them your address just to confirm the system is no longer being monitored. Hope that helps!

How do I reset the Master code in DAS NX-4--8 alarm system when the existing Master Code is not known ?


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)

MY ALARM SYSTEM KEEP BEEPING UNCONTROLABLY..ADEMCO ALARM


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 just moved into a house and it has an alarm system that has westinghouse on it. There are sensors on every door and window down stairs. We have no idea how to turn it on and get it set up.


Call an alarm company like ADT. If they can use it they will. it will require some minor reprogramming and they will check all sensors, if the use it. 1-800-ADT-ASAP.

Don't have the access code


Do you mean the access code for turning off an alarm or arming the system before leaving? If so, NO. You would have to know the original code to even enter programming to change the access code. Contact your realtor and have them get you in contact with the previous owner. Find out the code from them. If they properly removed their code before moving from the house use the default code, 1234. Good Luck.
