Sequence of Operations
These are the standards in SynC Standards that cover Sequence of Operations. Each one is a complete, plain-language specification: the scope it applies to, the requirements that govern it, and a structured equipment datasheet listing the values a project has to decide, with the standards each is verified against. All of it is written and maintained by SynC, free to read without an account, and published under CC BY 4.0.
A standard usually carries several topics, so most of the entries below also appear under neighbouring subjects. The topics each one carries are listed on its own page.
Standards
- Control Systems Integration and Testing
The integration, configuration, and acceptance-testing scope performed by the control system integrator on an industrial, process, or water and wastewater treatment project, whether the plant is new, expanded, or migrated to a replacement control platform. Covers the division of responsibility between the integrator, the electrical trade, the mechanical and process trade, and the packaged-equipment vendors; the authorship and content of the control narratives; tag and point naming per ANSI/ISA-5.1; the controlled I/O list and the loop diagrams per ANSI/ISA-5.4; the software configuration management workflow from first baseline through as-built; the integration of packaged-skid controls into the plant SCADA; the integrator's secure delivery of the configured system; the integration-seam verification of safety instrumented functions; the factory acceptance test, site acceptance test, site integration test, loop checks, performance verification test, and endurance test under ANSI/ISA-62381 and ANSI/ISA-62382; the commissioning sequence; training on the narratives and the maintenance of the delivered configuration; as-built documentation; the integration warranty; and the turnover of source configuration.
- Fire Alarm Systems
Protected premises fire alarm and signaling systems for commercial, institutional, industrial, mercantile, assembly, healthcare, educational, and multi-family residential buildings. Covers the fire alarm control unit, annunciation, addressable and conventional architectures, automatic and manual initiating devices, waterflow and supervisory signal devices, audible and visible notification appliances, in-building emergency voice/alarm communications, circuit class and pathway survivability, primary and secondary power, off-premises signal transmission to a supervising station, fire alarm wiring, emergency control function interfaces, and acceptance testing.
- Lighting Controls
The interior lighting control system of a commercial, institutional, or industrial building: the occupancy and vacancy sensors, daylight sensors, time schedules, manual control stations, relay panels, lighting contactors, lighting-control panelboards, room controllers, networked and luminaire-level control systems, and the management software that together decide when each luminaire is on, off, or at an intermediate level. Covers the control architecture and its network, the control signal and protocol delivered to the luminaire driver and the minimum light level the system commands, occupancy and vacancy sensing, daylight-responsive control, time scheduling and override, manual control, branch-circuit switching equipment, automatic receptacle control, demand-responsive control, the interfaces to the building automation system, motorized shades, and other building systems, the UL 924 override device that returns a controlled egress luminaire to full output, the low-voltage control wiring, the documented sequences of operation, startup, programming, functional testing, training, warranty, and spares.
