Branch speaker wiring
Signature modules are used to connect individual floor branch
speaker circuits to the main riser. Single channel branch speaker
circuits can be wired as Class A (Style Z) using the SIGA-UM
module. Class B (Style Y) circuit configuration can be
accomplished using either the SIGA-UM or SIGA-CC2 modules.
The branch speaker circuits of two channels can be wired as
Class B (style Y) circuits using the SIGA-CC2 module.
