The problem increased when the system went offline when I tried to rearm away and I had no way of knowing the current status of the system. This continued for days to the point I was ready to return the device, particularly after I tried a remote disarm/alarm when the system indicated “armed stay” knowing I had armed the system away. Numerous “device offline” followed by “device online” alerts (as many as one a hour in a 24 hr period). The first device has behaved inconsistently from the beginning. In the second instance the distance is approximately 3ft. In the first instance (residence) the distance is approximately 15ft. The only difference between the two homes is router proximity to the Nexx device. Both devices are identical, connected to identical alarm systems on identical wifi systems. The first Nexx was purchased through Amazon followed approximately 45 days later by the second when offered at a discount by the company. Having two residences two hours apart made smart features critical for our older DSC alarm systems. The previous device/App was quite robust compared to Nexx and at the same price point. The keypads are just an interface.I was looking for a replacement after my previous device quit working when the company shut down their servers and went out of business.
That's also where the main system board is. In many homes it's going to be in the master suite closet, or an electrical or utility room. Your main system battery is located in a beige or grey metal box about 16" square.
Key in # and the location number, and the panel will read back the installer code one digit at a time. The details by system will vary, but the programming section number that shows on the display will be the location for the installer code (on _most_ panels this will be 20). Unless the system has had an installer lockout feature activated, the panel should go into program mode. Within 50 seconds, on any keypad press * + # at the same time. Wait a minute, then reconnect power in the opposite order. Nearly all Ademco family (this includes First Alert, Security Link, and several ADT models) panels can retrieve the Installer code by disconnecting the battery, then the AC power. What am I missing with the wiring and components? How can I reset the master code so that I can start using the system and clearing some of these alarms? I found some type of annunciator located inside an HVAC return duct very near to the touchpad however, both the annunciator and the touchpad seem to be wired directly into my breaker box. There is no battery in the touchpad, nor can I find any type of control panel in the house with a battery.
I've read a few forum threads and the FAQ and I thought I might be onto something about how to reset the system so I killed the power to the whole house which didn't turn off the touchpad. I have contacted ADT however, they will not send anyone over to help reset the code without signing up for a 3-yr monitoring program at a ridiculous monthly rate which I am not willing to pay.
I do not know the master code, and have tried some of the basic codes like 1234, 9999, 1111, etc. I have replaced all of the sensor batteries however, the alarm messages still appear. In addition, just recently there is a new message which reads "LOW SYSTEM BAT". As best I can tell, all of the sensors attached to the unit now have a "CHECK XX" message on the touchpad. Over the years the system will periodically pop-up a new "CHECK XX FRONT DOOR" or similar message, which I've just attributed to low batteries in the sensors. However, recently the system has started to randomly go off with a constant beeping - usually at 3:00 in the morning when we are fast asleep! I can turn off the beeping by just hitting the off button on the control pad, but I would like to understand why this is happening and fix the problem. Up until recently, when doors opened the system chirps and that's about all that happens.
The touchpad says it is an ADT Safewatch Pro 3000. I have lived in my home for about 4-years or so now, and the home came equipped with an alarm system which we have never activated.
