Data Sheet
24LI
24 Line Module
The DVS-21 is capable of connecting not just our own but also third-party de-
vices. The module 4NPA makes possible an LF (low frequency) connection and
control over the C and V point of four devices.
In order to meet other control requirements the line module 24LI is additionally
required.
Application example for the 24LI with PA and intercom systems
The line module 24LI manages various control functions when using one or more
4NPA modules.
The individual lines are independent of one another. If, for example, third-party
devices are connected with line technology, a key/button is required for each line,
which means e.g. with a 24LI-module four call stations each with three double
toggles can be switched in.
More about the various applications can be found in the data sheet for the 4NPA
module.
