Networkable Analogue Addressable Fire Alarm Panel XFP


Context Plus’s XFP range of networkable analogue addressable fire panels offer high performance at a competitive price.

Certified to the latest versions of EN54 parts 2 & 4 by the Loss Prevention Certification Board, two versions are available – a cost-effective single loop 16 zone panel in a plastic enclosure and a robust 1 or 2 loop 32 zone metal panel.

Ideal for use in office blocks, shopping complexes and big industrial sites as well as smaller stand-alone applications, both versions offer an array of user and installer-friendly features, including:-

  • Full compatibility with Apollo’s XP95/Discovery and Hochiki’s ESP protocols
  • The ability to interconnect up to eight XFP main panels (any variant) onto a two wire RS485 network. Alternatively, up to eight XFP repeaters can be connected to a non-networked XFP main panel
  • Combined keypad / keyswitch entry to Access Levels 2 & 3
  • Two independently programmable conventional sounder circuits
  • Two programmable inputs
  • A fault output relay and three programmable relay outputs with voltage free changeover contacts
  • Three zone dependency functions (A, B & C to EN54-2 Clause 7.12) A day/night (building occupied/unoccupied) function
  • An investigation delay period function
  • Individual sensitivity settings for each device
  • A phased evacuation and delays to outputs facility (to EN54-2 Clause 7.11)
  • An alarm counter that records the number of times the panel has been in an alarm state (to EN54-2 Clause 7.13)
  • Powerful short circuit protected loop drivers, capable of supporting up to 40 loop
  • powered 10mA sounders per loop
  • An integral EN54-4/A2 switch mode PSU rated @ 185-260V a.c. 50/60Hz (1.4A on a 16 zone panel, 3A on a 32 zone panel)
  • Earth fault monitoring
  • An easy to read, 80 character back-lit display
  • 40 characters of custom text per device
  • 999 event monitoring
  • Comprehensive test facilities (to EN54-2 Clause 10) and a wide range of maintenance & commissioning functions including auto-learn loops, monitor a point, test outputs, one man walk test and loop continuity test
  • An intuitive Windows based upload-download PC program that allows the system to be programmed quickly and easily
  • Full compatibility with Context Plus’ Hush Button fire alarm solution for houses of multiple occupation
  • Optional flush-mounting stainless steel enclosures available (for 32 zone XFP panels only)
