● Control for synchronising the travelling speed of two identical 24 V- actuators of the series G, S or SG on a Vent or Smoke and Heat Vent (SHV). Not suitable for actuators type G201, G205, G209, G401, G405, G409

● Current input of each actuator max. 4 A (SYN 2d-8) or 8 A (SYN 2d-16)

● Both actuators are de-energised if any of them should fail

● Power supply and control must be provided by a single 24 V- actuator output of a SHEVS Control Centre / Control. The use of K + G / Grasl Control Centres is recommended. Compatibility is to be checked for thirdparty controls. The travel direction of the actuators must not be switched directly. Not to be operated with the Control Centre RWZ 1a and the Control RWD 1a

● Selectable functions:
− “Sxxxx actuator” (must be activated for actuators type Sxxx)
− “Synchronisation OFF” (there is no synchronisation of the travelling speed of the actuators, but both actuators are switched off if one of them fails)

● Internal indicators a and z

● Plastic enclosure, light grey (like RAL 7035)
