DSC PowerSeries Pro - HS65WPSNA (S) Power Adapter

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)

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 ).

At a glance

Panel troubles tied to adapter power

Measurement points

1. AC input to adapter — listed voltage range
2. 18 VDC at panel DC+/DC− — under load with all modules connected
3. Battery terminals — charge voltage after 24 h restore

Fast checklist

1. Verify incoming AC to adapter.
2. Verify 18 VDC output polarity at panel.
3. Verify earth ground tie per install diagram.
4. Complete Battery Calculation Chart before adding modules.

Wiring and mounting checks

• Secure DC+/DC− terminations — loose screws cause intermittent AUX trouble.
• Route Class 2 wiring separately from AC mains and bell circuits.
• Confirm panel-side voltage ≥ manual minimum with all keypads powered.

Load troubleshooting

• Add modules one at a time — if trouble appears after specific module, that device exceeds budget.
• HS3032/3128/3248 share Corbus/AUX budget — reserve 100 mA for Corbus before accessories.

Class 2 external mount

When adapter is outside panel enclosure, use Class 2 wiring and follow AHJ inspection rules.

Compliance context

Confirm UL/ULC/EN50131 project documentation before final inspection — HS65WPSNAS for ULC commercial fire/burg hardwired installs.

Model selection

Not a substitute for

• PowerSeries PC1616/1832/1864 16.5 VAC transformer installs
• Neo panel internal power supplies
• Third-party 18 VDC supplies not listed for Pro panels

Install sequence

1. Confirm project specifies HS65WPSNA, HS65WPSNAS, or regional HS65WPS variant.
2. Mount adapter in enclosure or external location per listing requirements.
3. Route Class 2 low-voltage wiring when adapter is outside the panel cabinet.
4. Connect DC+ / DC− to panel power input; tie earth ground per install diagram.
5. Apply AC mains; verify 18 VDC at panel DC terminals before loading Corbus.
6. Install and connect standby battery; allow charge period per manual.
7. Size battery using PowerSeries Pro Battery Calculation Chart for total load.
8. Add Corbus keypads and modules one at a time; recheck voltage under load.
9. Complete [902] module enrollment only after stable power confirmed.
10. Run full walk test and reporting test before handoff.

Field reminder

External adapter mount requires Class 2 wiring to panel DC input — label circuit at both ends.

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.
