Wireless alerting systems of the lisa and lisa-signolux product range convert acoustic signals, such as when the doorbell or telephone rings, into flashes of light or vibrating pulses. Wherever you are inside or outside the house, you can’t miss a signal.
The transmission and reception equipment is ready to use immediately; there is no need for any elaborate cabling.
Humantechnik's alerting systems are available in two varieties:
a) the lisa RF system and
b) the younger lisa-signolux RF system.
How does an alerting system work?
An alerting system consists of at least one transmitter and one receiver. The transmitter picks up signals from a variety of different sources - such as the telephone or the doorbell - and transmits them to the receiver. The reproduces the transmitted information as light or vibrating pulses.
Means of transmission
RF transmission: Both the systems »lisa RF« and »lisa-signolux« use radio frequency. No wiring is necessary between the transmitters and receivers. The receivers of both systems can be placed as needed or even used in a portable manner.
The newer signolux system uses digital coding when transmitting. This enables interference-free operation without restrictions due to defined radio channels. Thus, for example, the operation of a large number of separate systems within a building is possible without any problems.
Due to the different transmission format, lisa-RF and signolux devices are not compatible with each other.
