Multiplex System Sample Clauses

Multiplex System. For superior system integrity, the networked multiplex system shall meet the following minimum component requirements: • The network system must be Peer to Peer technology based on RS485 protocol. No one module shall hold the programming for other modules. One or two modules on a network referred to as Peer to Peer, while the rest of the network consists of a one master and several slaves is not considered Peer to Peer for this application. • Modules shall be IP67 rated to handle the extreme operating environment found in the fire service industry. • All modules shall be solid state circuitry utilizing MOS-FET technology and utilize Deutsch series input/output connectors. • Each module that controls a device shall hold its own configuration program. • Each module should be able to function as a standalone module. No “add-on” module will be acceptable to achieve this form of operation. • Load shedding power management (8 levels). • Switch input capability for chassis functions. • Responsible for lighting device activation. • Self-contained diagnostic indicators. • Wire harness needed to interface electrical devices with multiplex modules. • The grounds from each device should return to main ground trunk in each sub harness by the use of ultrasonic splices. All harnessing, wiring and connectors shall be manufactured to the following standards/guidelines. No exceptions. • NFPA 1901-Standard for Automotive Fire Apparatus • SAE J1127 and J1127 • IPC/WHMA-A-620 – Requirements and Acceptance for Cable and Wire Harness Assemblies. (Class 3 – High Performance Electronic Products) • All wiring harness securement shall be provided with stainless steel hard clamps with a minimum of plastic wire ties used in these areas. The overall covering of the conductors shall be loom or braid.
