Installation, Startup & Commissioning
Installation Services
At MDC Systems, we specialize in the installation of custom-built gas detection systems for your specific application. With our internal training program and training from the manufacturers along with our C-7 Contractors License, we are fully equipped to install low-voltage gas detection systems in California. MDC Systems utilizes our years of experience, and best-known methods and practices for state-of-the-art GLSS installations. We have adopted the latest technology and expertise to ensure a robust trouble-free code compliant system and to achieve customer satisfaction. Our installation services include:
- GLSS Design Plans: Installs should always start with a good set of plans detailing the area of work, equipment specifications, device locations, wire type/routing, mounting heights, and sequence of operations.
- Mounting of Sensors & Equipment: We install sensors, controllers, PLC panels, seismic sensors, exhaust pressure monitors and audio/visual horns, strobes and/or beacons to optimize system performance.
- Sample Tubing & Duct Installation: We install FEP and PTFE low absorption sample tubing and exhaust duct mounts or saddles for effective gas detection.
- Conduit & Wiring Installation: Our team ensures that conduit and shielded control wiring are installed according to NEC standards for safe and reliable operation.
- Emergency & Safety Systems: We install emergency gas off pull stations, horn/strobes, leak detection systems, seismic switches, and pressure switches for a fully integrated safety solution.
- Signage Installation: Signage is installed to identify horn/strobes, pull stations, and control room locations for ease of use and safety.
- System Labeling: We ensure all sensors, wires, controllers, tubing, and electrical circuit breakers are clearly labeled for maintenance, troubleshooting and operational ease.
- Client-Approved Device Locations: Devices are installed in locations approved by the client with ongoing service and maintenance in mind.
Start-Up and Commissioning Services
A successful system startup requires the right team. MDC Systems ensures that knowledgeable and experienced personnel are on-site to oversee the commissioning process, ensuring a smooth startup of the system, efficient setup and equipment checkout testing. Our approach includes:
- Standby Power Source: Ensure breakers power source is clearly marked on our panel for power isolation and feed. Ensure standby power source handles the load of the system.
- Initial Power-Up: This involves front-end to back-end power up sequence in a safe, controlled power-up of all field equipment, verifying all I/O including failsafe shutdowns.
- Field Device Checkout: Comprehensive testing of each field device input, ensuring every sensor and connection is verified from the end device to the controller or HMI screen.
- Operational System Checkout: Verifying system operations according to the sequence of operations (SOO) shown in functional matrix to ensure everything functions as designed.
- Client Acceptance: We ensure the system meets client expectations by including them in SOO functional testing verifying all alarm output features are operational and satisfactory.
- Third-Party Permit Testing: We provide necessary support for City inspection gas challenge and other system input testing for system functionality verification and permit signoff.
- Operations and Maintenance Manual (O&M): Development of operations and maintenance manual specific to the system and site and turned over to ownership.
- Operations & Maintenance Training: We offer training in system operation and maintenance, providing documentation for ongoing support.
- System Ownership Transfer: Once the system has been permitted, tested and the client has been trained, we proudly transfer ownership to our clients and offer continued support.
