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

Wheelock PS-8-LP POWERPATH

Wheelock PS-8-LP POWERPATH

The Wheelock PS-8-LP POWERPATH by Eaton is a supervised remote power supply and battery charger housed in a compact low-profile cabinet designed to drive and supervise fire alarm Notification Appliance Circuits (NACs) with an additional 8 amps of regulated, filtered 24 VDC power distributed across four outputs. It connects to any 12 V or 24 V (FWR or DC) Fire Alarm Control Panel via a NAC input or a dry contact, making it a versatile NAC expansion and auxiliary power resource on nearly any modern FACP. Out of the box, it supports four Class B, two Class A, or a 2 Class B + 1 Class A combination; with the optional plug-in PS-EXP module, capacity climbs to eight Class B or four Class A NACs.

Features

8 amps of filtered, regulated 24 VDC NAC power across 4 outputs
Supports 4 Class B or 2 Class A NACs (flexible configurations)
PS-EXP optional module expands to 8 Class B or 4 Class A NACs
Connects to 12 V or 24 V FACPs via NAC input or dry contact
Auxiliary power output: 2.5 A (alarm/AC-loss disconnected) or 0.240 A constant
Onboard 7 AH battery capacity within lockable chassis
External battery cabinet option for up to 33 AH (pending UL testing)
Steady or Code 3 temporal horn output with strobe-sync options

Benefits

The PS-8-LP POWERPATH addresses one of the most common fire alarm design headaches: a panel’s onboard NACs aren’t enough to notify the whole building, especially once ADA-compliant strobes are added room-by-room. Instead of replacing the control panel, integrators drop in a PS-8-LP to add 8 amps of clean supervised NAC current plus flexible NAC class mixing that matches whatever the specification calls for. The optional PS-EXP module doubles capacity again, which is often enough to cover an entire renovated floor without additional power supplies. Auxiliary output flexibility (alarm-disconnect vs constant) lets the same unit power ancillary accessories safely. For engineers, the result is cleaner drawings; for facility owners, it’s a cost-controlled path to NAC compliance.

Why Choose QuickShipFire?

Ready stock of the PS-8-LP for integrators expanding notification under ADA
Bundled quoting of PS-8-LP + PS-EXP when total NAC headroom is the real concern
Guidance on whether NAC input or dry contact is the right FACP interface for your panel
Battery sizing advice for the 7 AH chassis vs external 33 AH cabinet option
Quick answers about class mixing and per-output load balancing pre-purchase
