Overview
HS65WPSNA-family adapters provide external power conversion for PowerSeries Pro installations.
Official source
- Product page: DSC HS65WPSNA / HS65WPSNAS (ID 2660)
Electrical role
- Supplies 18 VDC to the PowerSeries Pro alarm controller via DC+ / DC− terminals.
- Required for HS3032 / HS3128 / HS3248 when not using an alternate listed power configuration.
Model naming (Installation Manual v1.1)
| Model | Use |
|---|---|
| HS65WPSNA | UL/ULC listed — cord-connected adapter |
| HS65WPSNAS | ULC commercial fire/burg — hardwired variant |
| HS65WPS | Non-NA / internal mount configurations per manual |
When mounted outside the panel enclosure, use Class 2 wiring to the DC input. Ground the adapter earth terminal per the install diagram ( ties to panel ground screw ).

Error Codes
Panel troubles tied to adapter power
| Panel trouble | Likely cause | Action |
|---|---|---|
| AC Failure / No AC | Mains to adapter open | Verify outlet, cord, breaker |
| Low Battery / Battery Trouble | Battery not charging | Test 18 VDC at panel; replace battery if aged |
| AUX Power Trouble | Corbus load exceeds budget | Sum keypad/module mA; add HSM2300 if needed |
| Panel reset / reboot loops | Undervoltage under load | Measure DC at panel under full Corbus load |
| Ground fault (where shown) | DC− wiring fault | Inspect Class 2 run for shorts |
Measurement points
- AC input to adapter — listed voltage range
- 18 VDC at panel DC+/DC− — under load with all modules connected
- Battery terminals — charge voltage after 24 h restore
Fast checklist
- Verify incoming AC to adapter.
- Verify 18 VDC output polarity at panel.
- Verify earth ground tie per install diagram.
- Complete Battery Calculation Chart before adding modules.
