Multiple Entry Modular systems require the following dipswitch settings on the back of the
TSMB3 unit:
Switches 4,5, &6 identify the entrance number. In the above example:
Entrance #1 = 4 OFF/ 5 OFF/ 6 OFF Entrance #2 = 4 ON / 5 OFF/ 6 OFF
Switch 3 If the door strike is connected to the SP333 (Tö2) = OFF (as shown at Entrance 2)
If the door strike is connected to the TSMB3 (Tö) = ON (as shown at Entrance 1)
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.
