Frequently Asked Questions

Q: What should I do if I encounter a TROUBLE LED flash pattern that is not listed in the manual?
- A: For any TROUBLE LED flash pattern not listed, please contact Alarm.com CORE Technical Support for assistance.
Q: How can I check the signal strength of the cellular network for the SEM?
- A: To check the signal strength, monitor the L4 signal level on the SEM. If it’s lower than 2 bars, consider changing the panel’s location or using a remote antenna option.

ADDRESSING THE KEYPAD

The default keypad address the SEM uses is Keypad 8 Device Address 23. If this keypad address is disabled, the SEM and panel will not communicate properly. However, at first power-up, the SEM will attempt to enable this address automatically. If unsuccessful, the address must be enabled manually via programming *196.

If another keypad is occupying this address already, a different address must be selected for the SEM. To select a different keypad address, manually adjust the dual in-line package DIP switches on the SEM to match the desired keypad address listed below. Then, exit programming via *99.
