Kentec launches iNS – Intelligent Networking Solutions

Kentec has launched its Intelligent Networking Solutions (iNS) providing advanced interconnectivity and monitoring of fire alarm control panel networks – critical where multiple panels are installed across a single site.

The sharing of status information between protected areas is essential to the management of site safety procedures, enabling the correct response when an event such as a fire occurs, for example, the direction of emergency responders and phased evacuation of building or areas.

The iNS product range is said to provide solutions for advanced networking of addressable fire alarm systems (both new and already-installed legacy panels such as Taktis and Syncro), and Remote Interface Modules (RIM) for simple interconnectivity solutions for non-networkable systems using ethernet networks. A Transient suppression module (TSM) provides network protection from Transient voltages.

The performance of any networked fire system relies on efficient data flow between panels. Losses in data will slow response times and can result in intermittent fault events as the panels fail to communicate correctly. iNS network analysers are compatible with the full range of Kentec addressable fire alarm panels, and even though Kentec’s panels use the most robust RS485 data protocols, Kevin Swann, Managing Director of Kentec, says the protocol can still be affected by poor-quality cables and extreme external interference:

“iNS network analysers are designed to continuously monitor network performance and where possible automatically compensate for changes in data quality and signal strength, ensuring the network is always preforming at its optimum level,” he says. “One of the key features of these modules is the monitoring and diagnostics function which not only makes fault finding quicker and easier, but also enables preventative maintenance by highlighting performance issues before a critical failure.”

iNS network analysers provide both copper and fibre optic network solutions. The fibre optic analyser can provide single mode, multi-mode and Bi-directional fibre optic solutions within a single module using plug-and-play fibre optic transceivers along with unique Digital Optical Monitoring for early warning of network issues.

RIM modules are said to provide “straightforward interconnectivity of panels” that are non-networkable or where it is not possible to run cables between panels. RIM modules monitor fire and fault status outputs on a fire alarm control panel and can transmit the active state of these outputs to another remote fire alarm control panel using an existing ethernet network. This enables two panels to share simple status information.

Transient Suppression Modules are designed to protect the fire alarm control panel from transients on the network cabling, and can also be used as an RS485 repeater/booster to extend the distance between panel nodes on an RS485 wired network.

“Using iNS products to manage fire alarm panel networks provides full visibility of network performance and mitigates infrastructure degradation by providing warning of any performance reductions,” concludes Kevin. “A highly valuable range of solutions for building occupiers, designed to make their lives more straightforward.”

AP Sensing: above-ground conveyor belt monitoring

AP Sensing is monitoring conveyor belts at the largest salt production site in Germany. The Zielitz Plant extracts approximately 12 million tons of crude salts per year and the mine operator, K+S, is an international mining company with sites across five continents.

K+S pursued an AP Sensing fire detection solution for early detection on conveyor belt bridges. Such bridges typically have a wooden floor, which would burn quickly. AP Sensing’s Linear Heat Detection (LHD) protects these conveyor belt bridges, and due to the project’s success and AP Sensing’s scope of certifications, K+S and AP Sensing entered a firm partnership to equip further sites.

In total, 22 conveyor belts are monitored with 11 LHD devices spread across the entire site. The operator, K+S, conducted trials and a benchmark comparison at the beginning of the project, additionally testing thermo cameras and point sensors. But due to the salty air in the conveyor belt bridges, the other sensor types were unsatisfactory as the corrosion of components is high, visibility low, and the maintenance effort higher.

AP Sensing’s simple approach, combining our sensor cable along the conveyor and LHD units in different control rooms, is the best solution for this type of application and its tough environmental conditions.

Conveyor Belt Monitoring

The conveyor belts are used to transport the salt from the ground to the storage halls, mills, other production facilities and load out ramps. After an incident at another site where one conveyor belt bridge burned, K+S sought out a fire detection system. These conveyor belts are important to monitor as none of them are redundant.

Installation

Following a successful pilot installation, K+S installed 11 fibre optic LHD units. All units have two channels and work in a fully redundant setup. AP Sensing’s Sensor Cable Steel is installed along both sides of each conveyor to achieve maximum coverage and the fastest possible detection. The cable has been fixed with high temperature cable ties along a tension wire.

Fire Coverage

To guarantee quality and reliability in the harsh conditions of the mine, a robust and maintenance free fire detection system is necessary. This solution consists of over 10 km of cable distributed throughout the site, providing area coverage for the conveyors, three reclaim tunnels, the handling and preparation plant, and the train load out conveyor and bin.

Precision of detection is unaffected by wind, dust and harsh environmental effects. All LHD units transmit alarms via relay contacts to different alarm panels on site in order to inform the plant fire brigade immediately. Additionally, AP Sensing’s SmartVision™ asset visualisation software is in use to demonstrate the exact location of temperature events along the conveyors.

The project was successful and K+S used AP Sensing’s LHD solution for other K+S sites. AP Sensing’s DTS technology is ideal for the extreme environmental conditions often found in mines. It is fully certified, resilient and maintenance-free, withstanding extreme temperatures without losing monitoring capabilities. Fibre optic LHD provides a simple and cost-effective solution for minimising serious damage, protecting employees and reducing operational shutdowns.
