Abstract (en)
[origin: WO9211431A1] A closure system for one or several locks (L) of one or several openings (T) is remotely controllable by transmitter signals (I) and has a portable transmitter (S) that serves as a key (S) for radiating transmitter signals (I), i.e. unlocking transmitter signals (I) which cause the relevant locks (L) to be unlocked (Z) and/or locking transmitter signals (I) which cause the locks (L) to be locked (Z). After receiving the transmitter signals (I), a receiver (E) generates a control signal (Z) when it is in the range (W) of the transmitter (S). A locking element (B) that can be controlled by the control signal (Z) allows the relevant lock (L) to be locked and/or unlocked. The receiver (E) monitors a parameter of at least some received transmitter signals (I), such as their power or field intensity, and at least from time to time adjusts the range (W), i.e. the sensitivity of the receiver (E), and/or the transmitting power of the transmitter (S), in accordance with the parameters monitored.
