INSTALLATION MANUAL

Switches

There are three types of switches located on the rear of the SPP Precision panel: The INT 12V-EXT 16V switches
(one per zone), the ZNET/VNET switch and the SS/SC4-NO SS/SC-4 switch. These switches affect the function of
the S128P Multi-Room Controller in various ways depending upon system configuration.

INT 12V-EXT 16V Switch

As previously described, the INT 12V-EXT 16V switch selects between internally generated voltage from the S128P
Controller (+12 Volts DC) for use with Z•Pad Keypads and Olé Touchpads, or externally generated voltage from a
power supply connected to the front of the SPP Precision Panel to be utilized by Olé Touchpads and VIA! Touch
Panels. This selection applies only to the "Z#B 16V/12V OLÉ/ZPAD" punchdown location. Select INT 12V (UP) when
12VDC is required for keypads or touchpads. Selects EXT 16V (DOWN) when using an external 16VDC power supply
for touch panels or touchpads.

ZNET/VNET Switch

The ZNET-VNET switch selects between systems based on ELAN's ZNET (S66A and S128P Multi-Room Controllers)
and VNET (S86A/P ). This switch will always be in the ZNET position when installing the SPP with the S128P
Controller.
