Elaho Light Sensor
Overview
The Elaho Light Sensor provides light level measurement and lighting control
for the connected Elaho control system. The sensor measures lighting
conditions to maintain a programmed lighting output in both dimmed and
switched systems.
Light Sensor Head with Controller
Light Sensors are available in three models:
E-LS - Light Sensor head with controller
E-LSC - Light Sensor controller only
E-LSH - Light Sensor head only
Each controller supports one or two Light Sensor heads and is available in
white or black finish. A Light Sensor head may be installed remotely or within
the controller, using up to 1,000 feet (304 m) of 16 AWG (1.5 mm
controller. When using a pair of Light Sensor heads, both sensor heads
transmit their light readings to a single Light Sensor controller. The controller
averages the levels and uses them to control lighting within the space.
Custom Configuration
This document guides you through the installation and local configuration of
the Elaho Light Sensor. For more detailed information about the custom
configuration options available for the Light Sensor using ElahoAccess,
reference the ElahoAccess Mobile App integrated help system.
Note:
switch 2 must be enabled. Reference

The sensor measures lighting conditions to maintain a programmed lighting output in both dimmed and switched systems.
  • Page 2: Wire Specification

    Elaho control system. EchoConnect is a bidirectional protocol that uses one pair of wires (data + and data -) for both data and power. Echoflex recommends using Belden 8471 (or approved equal) Class 2 wire. The total combined length of an EchoConnect wire run (using Belden 8471, or equal) may not exceed 1,640 feet (500 m).
  • Page 3: Installation Environment

    Echoflex Installation Guide Elaho Light Sensor Installation Environment The Light Sensor controller is intended for installation to a finished ceiling surface, soft ceiling tile, or attached to a round junction box or single-gang RACO junction box. The controller operates in ambient temperatures of 0°C to 70°C, non-condensing humidity.

  • Page 5: Soft Ceiling Tile Installation

    Echoflex Installation Guide Elaho Light Sensor If you are installing the Primary and/or Optional (second) Light Sensor Head remotely from the controller, reference Installing Heads Remotely (optional) on page 7 , then return to these instructions. If you are not remoting a Light Sensor Head, proceed to Step 4.
  • Page 6 Echoflex Installation Guide Elaho Light Sensor If you are installing the sensor in series (continuing the data run) to other sensors, sensor controllers, or stations, use the provided EchoConnect pigtail and ESD ground pigtail to make the terminations. If you are not continuing the data run, the pigtails are not required, proceed to Step 3.
  • Page 7: Installing Heads Remotely (Optional)

    These wire runs must remain separate from EchoConnect wiring. Echoflex recommends using Belden 8471 (or equivalent) wire. Prepare a hole in the installation location (3/4” hole without adapter or 1” with adapter). Run Belden 8471 (or equivalent) between the controller and the Light Sensor head installation location.

  • Page 12: Switched Photo Sensor Operation

    Echoflex Installation Guide Elaho Light Sensor Switched Photo Sensor Operation When DIP switch 1 is set to Switched operation, the sensor by default performs threshold based activation of both a “Dark” and a “Bright” condition, which are determined by the lux threshold settings. Lighting actions occur after measurements have been maintained for the configured delay time.
