LiteMesh-Local – Wireless Emergency Monitoring System

LiteMesh Local is Liteplan’s simple wireless emergency lighting operating system gathering data from DALI compliant emergency lighting control gear. The system creates a secure, robust mesh using IQRF long range mesh technology. The data is displayed on a local user interface touchscreen. This features a simple floor plan layout of each level of the building showing the exact location of each emergency light fitting or exit sign. Any issues are displayed in a simple graphical format. As the DALI control gear carries out its function test on a monthly basis and duration test on an annual basis, compliance reports are generated by the user interface. These reports are held securely for a five year period, and can be accessed and downloaded at anytime. In addition to this, real time fault reporting is also generated, indicating what part requires replacement and its exact location, allowing for a fix first time resolution. One of the main features of the system is the installer led commissioning tool. This strong, contractor friendly tablet, features our LiteWork software that allows the scheme to be commissioned in a fraction of the time of traditional emergency lighting monitoring systems. Each emergency light fitting or exit sign is placed onto the pre-installed floorplan as its operator navigates their way around the building. Once this plot has been completed, the information is automatically sent directly to the user interface to become the final working layout of the touchscreen. Grouping and scheduling of emergency lighting tests is handled via commissioning tool, so no two adjacent fittings will test at the same time allowing for maximum emergency lighting coverage.

LiteMesh-Local – Wireless Emergency Monitoring System

Specifications

  • Simple to Navigate Touchscreen User Interface
  • Compatible with any Manufacturer's DALI Control Gear
  • Fault Locations show in Floorplan Format
  • Simple Installation and Commissioning Process
  • Robust and Secure Mesh Technology

The LiteMesh network uses the IQRF protocol. This features mesh hopping capability. A secure, scalable and resilient mesh network. The network becomes stronger, the more it grows.

Technical Mesh Data:

IQMESH® routing protocol utilising optimised directional flooding brings outstanding network robustness

IQRF® DPA commands (a standardising language) assure simple integration and interoperability

Multilayer security based on industry standard 128-AES is extended by dynamic keys generation and exchange which makes wireless communication significantly more immune to cyber-attacks.

FRC® (Fast Response Commands) dramatically increases network throughput and reliability.

SW: OS + DPA + Appl. + SDK

Band: 433 / 868 / 916 MHz

Network topology: Mesh

Range (device to device): 500+ meters line of sight, up to 100 meters within a building.

Range (device to gateway): Tens of kilometres

Native multi-hop: 240 hops per packet

Routing algorithm: Optimised directional flooding

Security: Multilayer, AES-128, dynamic keys

Directionality: Bi-directional

End Devices OTA Management: for all operations needed

Main benefit: easy adoption / reliability

LOW POWER

With 240 hops and robust routing, IQRF® is the best fit for large control applications, such as street lighting, emergency lighting or parking, where reliability and security is a must.

Each mesh hops data to the gateway which then reports to the user interface touchscreen, which displays information in a simple graphical format. The gateways are persistent without communication. Therefore, if for any reason communication is lost, data is held at the gateway until the signal is re-established.

The LiteWay gateway does not connect to the internet. Communication is sent from each fitting, through the mesh, to the user interface via the gateway, without the need to connect to the outside world. This reduces cost due to the mitigation of data management and storage.
