The IC2 Database Chip

The QwikBus™ system has 8 pin nonvolatile IC chips located on the back of each TSMB3

Speaker Microphone Module (in the Modular style Entry Panels) or TT33-2 Speaker

Microphone Module (in the Custom style Entry Panels). Each unit has this chip which

maintains the programming for that specific entry.

Arrows indicate mounting screws

NOTE: Special Tool shown above is required for opening VFS/FS panels as well as servicing

Modular Entry Panels. Part # 13510

If you have to replace a TSMB3 or TT33-2 unit, you can remove

the IC2 from the old unit and install it into the new unit so you do

not have to reprogram that entrance. When doing this

replacement, be sure to install it in the correct polarity indicated

by the mark on the chip.
