SYSTEM ARCHITECTURE
1.2.1 Architecture
The diagram illustrates the devices and connections that can eventually be managed by the MP500/4N, MP500/8 and MP500/16
control panels. For the maximum dimensions the system can reach (combinations of devices and their maximum number) see the
paragraph 1.2.3
Maximum system size

1.2.2 Bus Data
Control panel, keypads, readers, expansion modules and radio modules are interconnected by a 4-wire bus.
The 4 wires transmit information among the various devices and supply 12 V
⎓
power from the MP500/4N, MP500/8 or MP500/16
control panel to the keypad, readers, expansion modules, and radio modules.
The use of the bus noticeably simplifies the wiring, given that, for example, the information of a group of detectors located far from the
control panel and concentrated on a remote EP508 expansion module can be controlled with just 4 wires.
