FAQs
Which AlarmNet module fits my panel?
LTE-X/C/V/A and LyricLTE modules are not interchangeable — match SKU to panel and dealer platform (Total Connect 2.0, ADC, SecureNet, Telus).
Do I need an external antenna?
If installer cell RSSI is below spec in the panel location, **panel-approved external antenna kits move the antenna to attic or exterior wall per guide.

How do I test after installation?
Use panel walk test, zone status, and (if monitored) central station test per dealer procedure.
Can I mix 5800 and SiX sensors?
SiX sensors require ProSeries or Lyric; 5800 needs a 5800 receiver transceiver hardware — they do not enroll on the standard 345 MHz receiver alone.
