Sentry IT Gas and Fire Detection Solutions
Facilities ranging from small CNG filling stations to fleet maintenance buildings, wastewater lift stations to wastewater plants, compressors, pipelines, refineries and even data rooms and cell tower huts present a common set of risks of hazard gas. Combustible gases such as natural gas (Methane) or Hydrogen represent a risk for facilities due to fire or explosion. Toxic gases including Carbon Monoxide, Hydrogen Sulfide, Chlorine and many others represent a risk to personnel, while inert gases such as Nitrogen can cause Oxygen displacement leading to asphyxiation. Facility managers must identify hazardous gas risks, mitigate the possible causes and design continuous monitoring systems to warn of dangerous conditions. Many facilities also need to protect themselves from flame hazards.
Protection from gas hazards is not a one-size-fits-all proposition. Systems must be designed to provide the appropriate level of protection and response commensurate with the risk level and the resources available to install and manage the system. Sierra Monitor’s Sentry IT fire and gas detection solution includes standalone sensor modules that can be integrated into the user’s safety and control system, controller based systems with extremely flexible logic for customized response, and enterprise wide systems that incorporate Industrial Internet of Things (IIoT) functions such as network connectivity, web-server graphics capabilities, and cloud data analytics.
Selecting the Right Partner
As a top-tier supplier with 35 years of experience in a highly regulated industry, Sierra Monitor’s products carry numerous third party approvals including Underwriters Labs, Factory Mutual, and Safety Integrity Level ratings; and comply with most relevant international standards. Sierra Monitor has deep technical experience and the resources to advise, develop and integrate the correct facility safety solution. While selecting a fire and gas detection solution from a short list of top-tier suppliers, facilities safety managers should ask the following questions to compare the Return on Investment (ROI) between the alternatives:
- How long will it take to install the solution at my facility?
Facilities are complex constructions, and installing and wiring gas and flame sensor modules across the facility can be time consuming and therefore expensive. Sierra Monitor offers a range of wiring connectivity options on each sensor module, thereby simplifying and speeding up the installation process. The installer can choose the option that is right for a particular construction type or zone. The options include traditional analog 4-20 mA connectivity and various digital wiring options that can be configured in daisy chain, hub, or star topologies as required, minimizing wiring complexity.
- How long will it take to commission the entire system?
Sierra Monitor’s Sentry IT solution includes a unique AutoDiscovery capability that enables the controller to automatically discover all the sensor modules connected to the controller, thereby saving time and preventing errors from manual commissioning. A very simple programmable logic environment enables the facility manager to quickly implement closed loop detection and response workflow that is appropriate for their facility. A “one-button” test feature rapidly tests the logic and health of all the actuator devices like lights, horns and strobes that participate in the response workflow. A “one-step” upgrade capability allows the USB port to be used to rapidly update the operating system, firmware, application logic, and user programs; making it equally easy to re-commission a system.
- Over the life of the solution, how much time will be spent calibrating and recalibrating the sensor modules?
Sensor modules are often located in hard-to-reach places. Accessing and calibrating each sensor module individually is time consuming and requires multiple people. Sierra Monitor’s unique GlobalCal™ technology enables a single-person, non-intrusive, all-at-once based approach to calibrating all sensor modules at one time from the controller. There is no need for personnel to go the each sensor module to calibrate it. Another factor that adds to the cost associated with calibration is the frequency of re-calibration. Many of Sierra Monitor’s modules are approved by the various agencies for recalibration every six months versus the more standard three month re-calibration cycle required by most other vendors. The longer recalibration cycles are enabled by Sierra Monitor’s use of advanced Digital Signal Processing (DSP) based filtering algorithms. The combination of GlobalCal and less frequent re-calibration results in labor cost savings of up to 75% for Sierra Monitor’s customers.
- How can ongoing maintenance and replacement costs be lowered?
Predictive maintenance and replacement or re-calibration of sensor modules is superior compared to reactive maintenance or schedule-based maintenance. With Sierra Monitor’s SenseSafe™ technology, the controllers use raw voltage information from the sensor modules to assess drift, along with statistical process control algorithms to determine when re-calibration would be required for a particular sensor, or when a module might require replacement. The facilities safety manager can use this information to potentially further extend the re-calibration interval, or use this information to make a more informed decision on when to replace individual sensor modules.
- Does the solution support advanced analytics that could proactively highlight a safety issue well before it becomes critical?
The Sentry IT controllers have a very large amount of memory to log alarm and events. By defining different alarm levels, large amounts of time series data can be collected at the individual sensor module or zone level, and that data can be analyzed to identify low-level safety anomalies that can be addressed proactively.
- How long will it take to integrate the system with an existing building management system or Programmable Logic Controller (PLC) or to the cloud for remote monitoring and analytics?
The Sentry IT solution from Sierra Monitor incorporates a FieldServer gateway, the industry’s leading multi-protocol gateway product. The FieldServer gateway makes it very easy for the installer or integrator to complete the integration step in minutes or hours rather than days or weeks. From Navy ships to data centers and from pipelines to CNG facilities, Sierra Monitor’s gas and fire detection solutions are the preferred choice for the diligent and ROI-oriented facility management professional.
