£79.20 (inc VAT: £95.04)
Summary
The C-TEC XFP501/PSU is a replacement power supply unit designed for use with the C-TEC XFP range of addressable fire alarm control panels. Engineered as a direct service replacement, this PSU restores reliable mains and battery-backed power to XFP panels in the event of a fault or end-of-life replacement, helping installers quickly return systems to a fully operational state.
Featuring a 3A 24V DC switch mode design, the XFP501/PSU combines the functions of a power supply, battery charger, battery monitor and earth fault monitor in a single unit. It is compatible with the full XFP single and dual loop panel range, including XFP501, XFP502 and the related E-variant models, regardless of whether the panel is configured for Apollo XP95/Discovery or Hochiki ESP protocol.
Third-party certified by the LPCB to EN54 parts 2 and 4, the XFP501/PSU ensures any panel it is fitted into continues to meet the stringent power supply requirements demanded by BS 5839-1 compliant fire detection installations. It is supplied as a board-level assembly ready for fitting into the existing XFP enclosure by a competent fire alarm engineer.
