Wireless alerting systems of the lisa and 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. When using signolux, you may have to register the transmitters on the receivers first - nothing to worry about though, this is an easy task.

Humantechnik's alerting systems are available in a variety of versions:

a) the lisa RF system and
b) the classic lisa plug system and
c) the new 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.

Alerting systems are available with two different means of transmission.

RF transmission: Both the systems »lisa RF« and »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.

Plug-to-plug transmission: The »lisa plug system« makes use of the electrical installation within the house as a method of transmission. The devices are simply plugged in to an outlet. The transmitter is plugged into an outlet closest to the according signal source - for example the telephone - and the receiver is plugged into the room in which the signal is to be received. The transmission between transmitter and receiver is made from plug-to-plug.

Signals of light and vibration in every room - and even outside the house:
