The GC Lock Control SHEV is an additional control unit for SHEV air inlet door solution and enables simple and safe wiring of the components used on a single-leaf or double-leaf door. With the GC Lock Control SHEV the components in a smoke and heat extraction case are supplied with voltage and controlled by the regulated SHEV control unit. Due to the possibility of connecting a DC / DC converter to the GC Lock Control SHEV 24 V and also 12 V motorized locks or a combination of both variants can be operated. For daily access (no SHEV case) the power supply of motorized locks is also possible by connecting power supply units to the GC Lock Control SHEV. Thus, the GC Lock Control SHEV allows easy and safe use of different motorized locks (24 V or 12 V) within a SHEV air inlet door solution.
