8.2 Speaker Wiring

Each SKE-V70 supplies one NAC (Notification Appliance Circuit) for speaker connection.
The speaker circuit can be supervised and wired Class B (Style Y) or Class A (Style Z). The
speaker circuit is capable of 50 watts of power 70.7 Vrms (using the SKE-V70 Module). Refer
to Table 3-7 for wire lengths.

Note: When the SKE-V70 Module is installed, all speaker wiring must be separated by a minimum of 1/4” from

the low voltage wiring, and must exit the cabinet through its own opening.

Connecting the SKE-V70 to the Main Control Panel

Connect the SKE-V70 to the main control panel using the supplied wire harness. See Figure
8-3.

Note:

Speaker outputs of the SKE-450 must not be used when using the SKE-V70 because supervision will not

be provided at the SKE-450.
