Overview
What it is and how it fits the system.
The Xtralis VPS-250-STX5 is a 3A VESDA-E (Style E5) power supply unit finished in STX black to complement the appearance of VESDA-E Aspirating Smoke Detectors. Supporting 12-24Ah battery capacity (batteries not included), it delivers the current and charging capacity needed to meet EN54-4:1997+A1:2002+A2:2006. It provides external LED indicators and relay outputs via GPI for fault monitoring, and carries VdS approvals G220003 and G220018 alongside CE 0786-CPR-21681 and 0832-CPR-F2659.
Technical overview
VPS-250-STX5 pairs a 3A output with 12-24Ah battery sizing in an Xtralis VESDA-E power supply unit finished in STX Black. Cable knockouts and the overall housing line up with VESDA-E detector styling, so the unit sits alongside a detector as a visually matched installation, and charging is temperature-compensated to prolong battery life.
Certification is to EN54-4:1997+A1:2002+A2:2006, with approvals recorded as VdS: G220003 & G220018 and CE: 0786-CPR-21681 & 0832-CPR-F2659. Fault conditions report through relay outputs tied to a General Purpose Input, while external LED indicators show status at the enclosure.
Application guidance names the VESDA-E VEU detectors VEU-A00 and VEU-A10 as hosts supported at all fan speeds, within broad compatibility across VESDA-E aspirating smoke detectors; wiring and terminal detail belongs to the installation and application documentation. VPS-250-STX5 supersedes the earlier VPS-250-STX, and the VPS-220-STX5 provides a smaller 0.5A alternative in the same range.
