VPS-100US-120 Power Supply

The VPS-100US-120 Power Supply is VESDA by Xtralis’ dedicated power source engineered specifically to operate the full line of VESDA aspirating smoke detectors. It delivers supervised 24 VDC operating power plus an integrated battery charger that actively supervises and maintains the standby batteries so the protected environment retains early-warning detection even through utility power events. Whether an application calls for powering a single VLF-series unit or a small cluster of multiple detectors, the VPS-100US-120 is sized and certified as the right infrastructure layer beneath a VESDA install. For data centers, archives, telecom facilities, and other business-critical spaces where aspirating detection is specified, it eliminates the guesswork of pairing a general-purpose 24 VDC supply.

Features

  • 24 VDC operating power engineered for VESDA aspirating detectors
  • Integrated battery charger with supervision of standby batteries
  • Supports single-unit or multi-unit VESDA detector applications
  • Maintains detection during utility power interruption
  • Certified as a matched power source for VESDA aspirating systems
  • Eliminates guesswork of sizing third-party 24 VDC supplies
  • Designed for integration alongside VLF-250, VLF-500, and other VESDA units

Benefits

Choosing the VPS-100US-120 solves a quietly important problem: VESDA aspirating detectors need clean, stable 24 VDC with proper battery supervision, and mismatched generic supplies can lead to nuisance supervisory troubles, shortened detector life, or marginal backup performance. By specifying the matched VESDA power supply, integrators guarantee compatibility at the electrical-spec level and inherit the supervised battery charger engineered to maintain standby capacity correctly. That translates to fewer service calls, more predictable detector uptime, and cleaner panel logs which in turn helps the protected facility pass inspections without drama. For any organization already investing in VESDA-grade detection, it’s the right place to standardize the power layer.

Why Choose QuickShipFire?

  • Dedicated VESDA accessory stocking including power supplies often backordered elsewhere
  • Sizing guidance for customers running one VLF unit vs multiple VESDA detectors
  • Battery capacity recommendations aligned with local standby-time requirements
  • Fast-ship coordination for service techs replacing failed third-party power supplies
  • Real VESDA-familiar support we know the aspirating ecosystem, not just the datasheet
Why not just use a generic 24 VDC supply instead of the VPS-100US-120?
Generic supplies often lack the supervised battery charger behavior and filtering specified for VESDA aspirating detectors the matched unit removes compatibility and supervision risk.
Can one VPS-100US-120 power more than one VESDA detector?
Yes, the VPS-100US-120 is designed to support single-unit or multi-unit VESDA applications; the exact count depends on load calculations for your specific detector models.
How long can VESDA detectors run from the supervised batteries during a power loss?
Standby runtime depends on battery amp-hour rating, the connected detector load, and local standby-time codes your integrator should size batteries to meet the required duration.
Does the VPS-100US-120 supervise the batteries automatically?
Yes. The integrated charger supervises and maintains standby batteries, so degrading or missing batteries are reported rather than silently leaving you without backup.
Is this power supply only for VLF-family detectors or the entire VESDA line?
It's designed to power the entire line of VESDA by Xtralis aspirating smoke detectors, including VLF and other product families, subject to specific detector load compatibility.
What happens if utility power is lost during an active alarm?
Because the VPS-100US-120 maintains standby battery charge, the VESDA detectors can continue operating through a utility outage, maintaining early-warning coverage when it matters most.
Where does the VPS-100US-120 typically get installed in the protected space?
It's usually mounted near the VESDA detector(s) it powers in the same equipment room, electrical closet, or protected space with battery enclosure sized per the site standby plan.
