Litemesh Local

As many organisations, companies and facilities are working towards the new target of Net Zero 2030, the wireless control of emergency lighting is paramount on many agendas. This is a major first step in the reduction of a building’s CO2 impact, whilst maintaining compliance. 

As many organisations, companies and facilities are working towards the new target of Net Zero 2030, the wireless control of emergency lighting is paramount on many agendas. This is a major first step in the reduction of a building’s CO2 impact, whilst maintaining compliance. 

LiteMesh-Local is Liteplan’s robust, scale able and secure wireless emergency lighting platform. Providing the ultimate in compliance with a simple installation and commissioning process.

Operates away from crowded Bluetooth signals that have the potential for cross platform security issues.

A robust mesh system reporting the status of your building’s emergency lighting. Commands are processed using industry standard DALI (digital addressable lighting interface) protocols enabling multi-manufacturer compatibility.

The local user interface touchscreen displays faults in an ergonomic graphical format, guiding the user directly to any issues that require attention. Following function or duration tests, compliancy reports are held at the system and can be downloaded when required. 

The system operates with DALI emergency control gear which the system programs to carry out functions test once a month and a three-hour duration test once a year. This is all in keeping with the testing requirements of BS (EN) 50172:2004 and as referenced in the UK Emergency Lighting Code of Practice BS 5266-1:2016. Rather than using DALI bus cables, we employ a robust and secure 868MHz mesh network as the vehicle for the data. 

The schedule and timing of the function and duration tests can be programmed in keeping with the requirements of the building and its occupants. The system not only accurately reports on failures for a fix first time scenario, but can help large estates schedule maintenance more efficiently.

Testing can be set into unlimited groups, so that no two adjacent fittings are set to test at the same time. This allows for maximum coverage whilst emergency lighting batteries are recharging following duration tests. 

Historic compliance reports are held at the system for accountability and can be downloaded at anytime.

LiteWork Commissioning Tool

The LiteWork Commissioning Tool is a rugged tablet designed with the demands of site conditions in mind. It has the ability to communicate with individual emergency luminaires on the LiteMesh network. 

Each emergency fitting is signal strength located as the operator navigates the area and subsequently plotted directly onto the floorplan of the building. Once this simple process has been completed, the information is uploaded to either the LiteMesh-Cloud platform, or the LiteMesh-Local user interface.
