This is my first post and I hope this the right subform for this type of question. Here's my situation-
I have a 2-year contract with ADT security that expired a couple months ago. I disconnected their monitoring service, so my system is no longer being monitored by ADT. The system is a self containing SCW4047-433. I also disconnected my landline phone (we only use cellphones). My setup included a regular landline (disconnected) and also a GSM model GS3060 (just in case the landline was cut, I would still have a backup wireless connection). The past couple of months were fine, but tonight the system starts beeping every 10 seconds. I turned off the buzzer by pressing the # key. Now, the yellow triangle light is on the panel and the GSM module top triangle is flashing red. I tried to troubleshoot, and I received a 'failure to communicate' message.
How can I disconnect the communication for the GSM and wireless line so that there won't be an error anymore?
I have the installer's code and manuals, but I can't find the right place to disconnect both of them.
Thank you very much, and any help would be greatfully appreciated!
