4.1 The motherboard
The SmartLoop motherboard has a 32 bit microprocessor that controls all the control panel functions,
and 2 peripheral microprocessors (one per loop) that manage communications with the system
peripherals. INIM’s R & D professionals have developed and designed the SmartLoop motherboard
using ground-breaking new generation fire technologies that ensure maximum precision and
performance. Deployment of the most advanced reflow technology ensures high-noise immunity and
extreme accuracy. Each connection terminal is protected against electrical surges and is high-noise
immune capable. All terminals on the motherboard are clearly marked and easily identifiable (see
Figure below). The motherboard has been especially designed to accommodate with ease the various
SmartLoop attachment boards.
