Introduction

This section describes the system design and how this design can support the requirements of a customer.

The information in this section helps with initial sales and designing a system to the situation of the customer.

About the system

PRF/PRA is designed to install, setup and manage a lighting system in buildings of the following types:

  • Office

  • Small industry (for example a small workshop or warehouse)

  • Retail

  • Combinations of the types mentioned

The following tiers can be distinguished:

  • PRF is an easy to install standalone lighting system that doesn’t rely on gateways to connect to the cloud.

  • PRA is a connected lighting system that adds gateways to lighting devices to provide additional features.

PRF/PRA is optimized to connect maximum 200 lights per gateway for PRA (connected) or a light network for PRF (not-connected). This translates to office buildings with a floor area of up to 1000 m2 (10,500 to 11,000 ft2), or larger in buildings with lower lighting requirements (for example up to 10,000 m2 (105,000 to 110,000 ft2) for warehousing).

Multiple networks / gateways can be used to further scale up the system. Interact - PRF can easily be updated to PRA by adding gateway(s) to connect the system to the cloud.

The application areas of the PRF/PRA system are:

  • Newbuild
    The lighting installation is optimized for the building by design. The lighting design, placement of sensors, user interfaces, and the gateway is discussed with the customer upfront.

  • Renovation
    Existing luminaires will be replaced by new luminaires or lamps, keeping the existing electrical infrastructure and lighting design intact. Only the gateway needs an additional power and network outlet, which in most cases is not problematic.

Target audience

The proposition is aimed at companies who want to install, sell or use a state-of-the-art lighting system.

The target audiences for this document are:

  • Service provider/Installer - users for an organization that install, commission and manage systems on behalf of the customer.

  • Business owner/User (the customer) - users of the company who purchased a system.

The purpose of this section is not to transfer all knowledge needed to design, configure and maintain the system without external support. The aim is to provide sufficient knowledge to interact with the customer or third-party experts during all stages of the system lifecycle.

As there is an IT component part of the system proposition, it is advised to discuss with the customer about connecting the gateway to the customer’s IT network.

Roles and responsibilities

For a better understanding of the stakeholders that are being discussed in this document, below an overview of the different roles and their responsibilities.

Terms and definitions

Abbreviation Explanation

Access port

A switch or router port which is used to connect to an “end device”. An end device in this context is for example the Wireless Gateway.

IPv4

Internet Protocol version 4; IPv4 consists of a set of protocols that together enable communication of packets between network interfaces that are identified by 32 bit IPv4 addresses.

Light point

Either a lamp or a luminaire. When using smart lamps in a luminaire, the luminaire can consist of multiple lights. When using luminaires, each single luminaire counts as a light point.

Task level

Configurable light level on the task plane (80% of full output).

Background level

Configurable light level of 20% of task level, used to save energy when a space in not occupied.

Hold time

Configurable delay time from the moment the last movement has been detected until the start of the grace fading time.

Prolong time

Configurable time the background level is maintained at a fixed level.

Vacant level

Configurable light level used when an area is vacated. Prevents the light to switch off completely in case of security reasons (for example security cameras), or for comfort reasons. The level can also be set to completely off.
