Product Description

Leviton ACS20-DMW Smart Ceiling Mount Sensor, Multi-tech, Switching, 1-zone, 2,000 sq ft coverage, 120-277VAC

Description
The Leviton Smart Ceiling Mount Sensors (CMS) offer high performance, code compliant, advanced room configuration in one easy-to-install device. Installers can download the Smart Sensor App for quick-and-easy room configuration and testing with any iOS or Android device.
The CMS’s features meet advanced design requirements for standalone occupancy/vacancy sensing and ambient light
hold-OFF applications offering easy configuration and operational testing for occupancy/vacancy sensing, options for one or two ambient light hold-OFF zones, area control, demand response, plug load or receptacle control, and UL924 emergency lighting.

Easy Room Configuration
CMS allows you to configure the sensor based on how the space is used and to meet energy code requirements. All configuration is done using the Smart Sensor App. The Leviton Smart Sensor App is compatible with both Android and iOS smartphones or tablets. The app is easy to use with simple, intuitive on-screen menu options.
•Ambient Light Hold-OFF Calibration (AutoCal)
•Passive infrared (PIR) and ultrasonic (U/S) sensor sensitivity adjustments to reduce false ONs and false OFFs
•Ability to wirelessly network with other CMS and Smart Room Controllers to expand FOV coverage
•Define inputs as manual control, demand response, or emergency lighting
•PLVSW Low Voltage Keypads and SBK00 Wireless Switch can be used in manual-ON applications

Features
•Can be used to comply with IECC, ASHRAE 90.1. and 2022 Title 24, Part 6 requirements:
•Occupancy/vacancy sensing
•Demand response
•Plug load or receptacle control
•Available in 450 to 2,000 square foot field-of-view units
•All configuration is done using the Smart Sensor App
•For larger spaces, up to five Smart Ceiling Mount Sensors and Smart Ceiling Mount Room Controllers can be connected wirelessly to expand the FOV up to 10,000 sq ft
•Passive infrared (PIR) and multi-tech (PIR + ultrasonic) models available
•Manual area control available for 3-way/multi-way applications with the PLVSW Low Voltage Keypads or SBK00 Wireless Switch (must all be same style)
•For dual relay models (AC205-DMW and AC220-DMW), two keypads can be connected for manual control of each relay/lighting zone
•UL924 listed for emergency lighting:
•Can be connected to BMS (Building Management System) or any contact closure to force the lights full ON in case of emergency
•Ambient light hold-OFF
•AutoCal feature—Digital Daylighting Level automatically calibrates photocell to specified lighting design
•Two light pipes are included for both open (angled) and closed loop (flat and angled) ambient light hold-OFF
•The angled light pipe provides directional fine tuning and alignment to natural light source for closed loop applications
•Includes two interchangeable lenses for 8-12’ mounting heights and 13-20’ mounting heights as well as aisleway masks

Features (Cont’d)
•Ladderless Commissioning™ and programming through Bluetooth-enabled iOS or Android smart devices
•Visual RGB LED indicator for status and troubleshooting
•Scheduling:
•Change level, operating mode, daylighting mode (based on day of week and/or time of day)
•Easily test room configuration using a smart device as a calibration, measurement and testing tool
•Connect an OPP20 Power Pack to a two circuit room controller for a plug load control solution
•Industry-exclusive H.I.S. (High Inrush Stability) technology
•Tested to 1.2 million switching cycles under standard loads
•Zero-crossing circuitry for extended life of the relay
•Latching relay provides dependability and robust performance for all load types
•Industry-exclusive “fail safe” circuitry: in the event of product failure, return-to-close feature causes the relay to default ON which eliminates life safety concerns

App Features
Download the Smart Sensor App to an iOS or Android smart device and pair to the CMS using Bluetooth technology.
•Create custom templates for quick multi-room replication of sensor settings
•Select between auto-ON/auto-OFF and manual-ON/auto-OFF
•Set occupancy sensor time-out
•Enable/disable receptacle/HVAC control for secondary relay
•Initiate field-of-view walk test
•Select sensing technology for either PIR, U/S or multi-tech (PIR and U/S)
•Set PIR or U/S sensitivity independently
•Monitor status of all inputs
•Integrated occupancy sensor(s)
•Integrated photocell
•Local wall keypad
•Plug load
•Emergency UL924
•Demand response
•Enable 24 hour automatic calibration
•Set the offset of the secondary daylighting zone based off the primary daylighting zone
•Daylighting adjustments: open loop, closed loop, increase/decrease DDL
•Manually adjust DDL set point to fine tune for room type after auto-configuration
•Over-the-Air (OTA) updates: allows user to update SRC firmware in the field via the App
•Reset to factory defaults

Installation
•Easy installation into junction boxes with Leviton-exclusive screw guides, coasters and terminal blocks
•Front cover snaps on and off for ease of installation
•Sensors conveniently mount to a standard 4” x 4” square or octagon electrical box per NEC standards. The square junction box requires a mud ring
•Color matching via paintable front cover - does not affect warranty as long as the room controller is properly masked
