The side expansion slot on a Honeywell Lyric Alarm System is used for inserting a cellular communicator. The two (2) most popular cellular communicators used with the Honeywell Lyric Security System are the Honeywell LYRICLTE-A (AT&T LTE) and the Honeywell LYRICLTE-V (Verizon LTE). If the cover for this slot is removed, then it could indicate that someone was trying to disable the system's cellular communicator. For that reason, the system will go into a trouble condition to make sure that you are made aware of the issue. The trouble will clear once you reapply the expansion slot cover and then clear the trouble by arming and disarming the system.
