XV. NV-LSI12 Local Source Interrupt
A lower cost alternative to the LSA40 is the LSI12. This is a non-amplified local source interrupt. It is installed in the same way the LSA40
is installed, but the incoming local signal must be amplified, fig 20. This is a useful accessory where a local amplified signal is already
present.
