• Staircase time switch, electronical
  • Zero-cross switching for relay-saving switching and high lamp loads
  • Multi-functional device with 10 available functions, set at the front of the device
  • Additional multi-voltage input electrically isolated for AC/DC 8...240 V, e.g. für intercoms
  • Switch-off pre-warning (two double flashes) in accordance with DIN 18015-2 to avoid sudden darkness
  • Extended function activated via long button press
  • Immediate secondary switching (stair light switch) or prematurely switched off (pulse switch with switch-off delay)
  • Permanent switch
  • Electronic pulse light
  • Terminal layout same as ELPA 8
  • Extremely accurate
  • Push button input with electronic overload protection
  • Automatic 3 or 4 conductor detection (4 conductor with connection for floor lighting, 3 conductor no longer permitted for new systems)
