FF520 MFP 20 Zone Conventional Fire Panel View larger

MFP 20 Zone Conventional Fire Alarm Panel (expandable to 28 zones)



  • Microprocessor based design.
  • Robust metal enclosure c/w lift off lid & heavy-duty base connections.
  • 20 conventional Zone circuits (expandable to 28).
  • 4 conventional Sounder circuits.
  • Separate indicators for open circuit, short circuit, head-out, sounder & battery/power supply faults.
  • Non-latching class change sounder input, latching fire & non-latching fault outputs (via expansion loom).
  • Zone selectable short circuit=fire facility (pre-1980 BS, no resistors in call points).
  • Up to 8 two-wire Repeaters per Main panel.
  • Multi-lingual variants (subject to quantities).
  • Space for 2 x 12V 7Ah VRLA batteries.
  • Compatible with virtually all known conventional fire detectors including C-TEC's ActiV range.
  • Designed to comply with BS 5839-4 (this panel in not compliant with EN54-2/4 and should NOT be used in new UK or European installations).
