Closing sequence control device for two-leaf door with door closer transmits modulated and encoded signals between resting leaf and outer leaf or actuator

摘要

The door has a resting leaf (1) with a position sensor and an outer leaf (2) with an electrical actuator which blocks or releases the opening leaf based on the position of the resting leaf. Modulated and encoded signals or signal packets are wirelessly transmitted between the resting leaf and the outer leaf or the electrical actuator. In an active transmission system, signals are emitted from one or more transmitters and received by one or more receivers. In a passive transmission system, one or more interrogation devices are used to interrogate one or more read units, TAGS, or transponders, defining the state.
