Hartte SF-series

Hartte SF-series

Certified electric strikes for fire-protection systems from SF-series are applied in fire-doors with classification EI120 according to Resolution CPR 305/2011 and the EU harmonized standard for electric strikes 14846.

SF-series feature symmetric housing and 4 mm adjustment of the latch, which simplify mounting and punching process in fire doors.

Characteristic:

  • fire-rate EI120  
  • fail-secure (NC normally closed) or fail-safe (NO normally open)
  • symmetric housing
  •  size: width 20,5mm, height 75mm, depth 28,5mm, size of version with door status monitoring: width 20,5mm x height 81,8mm x depth 28,5mm
  • mechanical strength – break-in resistance 3500 N (350 kg)
  • mechanical strength – opening cycles 200.000
  • DIN-left and DIN-right doors
  • latch adjustable up to 4mm

Models of HARTTE SF line:

  • normally closed
  • normally open(mounting on additional lock)
  • normally closed low consumption

Above models available with door status monitoring (M) and/or varistor (V)
