System Capacity Limits

Quick Reference

This page consolidates all platform capacity limits for the Keilton+autani NLC system in one place. Individual limits are also noted in their respective topic articles throughout this guide.

Overview

The Keilton+autani platform enforces specific capacity limits to ensure reliable wireless communication and system performance. Understanding these limits is essential when planning your installation, especially for larger facilities that may require multiple zones.

Capacity Limits Reference

Category Limit What Happens If Exceeded
Online Nodes Up to 100 online nodes per zone Divide into additional zones
Luminaire / Group A light can belong to up to 20 groups Adding a 21st group removes the light from the first group automatically
Scenes (per light) Up to 32 scenes per light Adding a 33rd scene removes the first scene from that light
Scenes (per zone) Up to 66 scenes per zone Includes Quick Create Scenes and scenes from template creation
Schedules Up to 32 schedules per zone Additional schedules cannot be created
Switches Up to 32 switches per zone Area sensors count toward this limit (see details below)
Zones Unlimited zones per app on a mobile phone No restriction
Data Persistence All settings saved on individual luminaire controllers System continues operating after power outages or without network connection

Online Node Details

Online nodes include the following device types:

  • LLLC sensors — IFS108, EFS106, EFS104, etc.
  • Controllers — PPA102S, PPA104S, FA102, WF20R, PPA109, etc.
  • Area sensors — CS107S, CS107D, etc.
  • Sensor switches — IWS102, etc.
  • Dongles and gateways — CR01, CR02, CR04, BG01, etc.

Exclusions from the 100-Node Limit

Wall switches and battery-powered BCS107 sensors are not counted toward the 100 online node limit. However, they do count toward other limits (see Switch details below).

Zone Sizing Guidelines

When dividing a site into zones, follow these physical constraints to maintain reliable wireless coverage:

Guideline Recommendation
Maximum radius 150 feet
Maximum area 9,000 square feet
Signal obstructions Avoid concrete walls or large metal objects within a zone
Node count No more than 100 online nodes per zone

Switch Limit Details

The 32-switch limit per zone is calculated separately from the 100-node light limit. Adding switches to a zone does not reduce the available online node count.

Devices that count toward the 32-switch limit:

  • Battery-powered switches — WP1013, WP1018, WP1025, etc.
  • Line voltage switches — WP1013S, WP1017S
  • Area sensors — CS107D, CS107S, BCS107

Tip

Because area sensors count toward both the switch limit (32) and potentially the online node limit (100 for CS107D and CS107S, but not BCS107), plan your sensor placement with both limits in mind.

Planning with Capacity Limits

Control Intent Narrative (CIN) and Sequences of Operations (SOO)

Before purchasing and installing an NLC system, facility managers should define owner requirements and control system goals in a design document called the Control Intent Narrative (CIN) and Sequences of Operations (SOO). Two industry standards that can assist in creating these documents are:

  1. ANSI/IES LP-6-20, Lighting Control Systems: Properties, Selection, and Specification
  2. ANSI/IES LP-16-22, Documenting Control Intent Narratives and Sequences of Operations

At a minimum, the CIN and SOO should contain:

  • A floor plan and the functions of each zone
  • Each light's model number, quantity, and position
  • Zone definitions based on lighting functions, observing the 100-node and physical size limits above
  • Group number, group name, scene number, scene name, and approximate scene design for each zone
  • Switch type and number, as well as the function of buttons for each zone
