I have an ADT Safewatch Pro 3000 with wired and wireless sensors and I’m adding an Alarm.com SEM300 to it. I’ve followed the steps here and have successfully connected the SEM to the panel and powered it up.
But upon power up, the panel doesn’t perform a zone scan; it just behaves as if the SEM doesn’t exist.
I’ve cycled power and attempted a communication test as instructed on the Surety System Manager page but nothing changes. I noticed the following troubleshooting tip in the SEM installation guide. Any suggestions? Appreciate the help!
Hi, the PROM version is 9.12 from 2010. I’m attaching photos of the SEM and panel.
I used the black, green, and white wires from a 22/4 cable from the SEM connectors to connect to terminals 4, 6, and 7 on the panel respectively. The red wire was left unconnected.
The red power wire included with the SEM connects from the SEM screwpost to the battery in the panel box. The panel’s existing battery connection is piggybacked on top at the battery terminal.
Could you provide a list of devices on the panel? Keypads with the model numbers, zone expander and any other devices.
Do you have a multimeter to check voltage on the panel? Could you check the first two terminals on the panel checking for AC power? Could you check the power on the SEM300 by checking for DC power on the black and red wires?
