FAQs
What does this adapter do?
Provides 18 VDC to PowerSeries Pro panel DC+/DC− input — primary power path for HS3032/3128/3248.
HS65WPSNA vs HS65WPSNAS?
HS65WPSNA = cord-connected UL/ULC; HS65WPSNAS = hardwired ULC commercial fire/burg variant.
Can I use a generic 18 VDC power supply?
Use listed HS65WPS family only — unlisted supplies risk UL/ULC compliance and unstable Corbus voltage.
Class 2 wiring when mounted outside?
Yes — when adapter is outside panel cabinet, route Class 2 to DC input per install manual.
How do I size the battery?
Use PowerSeries Pro Battery Calculation Chart — include Corbus keypads, modules, and communicator load.
What voltage should I measure at the panel?
18 VDC at DC+/DC− under full load — retest after adding each Corbus module.
Can one adapter power multiple panels?
No — one HS65WPSNA-family adapter per Pro panel DC input.
What if 18 VDC sags when Corbus loads?
Reduce modules, upgrade battery, or add HSM2300 auxiliary supply per Pro install manual.
