System Notes – 2 wire COLOR with Single Modular Entry

A Single Entry Modular system requires the following dipswitch settings on the back of the

TSMB3 unit:

Switches 4, 5, & 6 identify the entrance number (all OFF = Entrance 1)

Switch 3 If the door strike is to be connected to the SP333 (Tö1) = OFF

If the door strike is to be connected to the TSMB3 (Tö) = ON

For more information refer to Page 10 - Dipswitch Settings.

Be sure that the End of Line Jumpers are used on the camera circuit board and in the last

monitor on each riser. If the last unit on a riser is an audio only unit, the End of Line Jumper

would still be used on the last monitor on that riser. This is important for best picture quality.

For more information refer to Page 12 - End of Line Jumper Locations.

When connecting C333-2 harness between SP333 and SNT333, ALWAYS observe 24VDC Polarity.
