Overview

This document details the Naos emergency lighting luminaire by Daisalux, covering its design, components, performance, and compliance with international standards.

Standards and Compliance

• Complies with EN 60598-2-22 and EN 60598-1 for luminaires.
• Meets French standards NF C 71-800 series and UTE C 71-800 series for emergency lighting.
• Adheres to EN 1838 for emergency lighting requirements and EN ISO 7010 for safety signage.
• Conforms to European Directives including Low Voltage (2014/35/EU), Electromagnetic Compatibility (2014/30/EU), RoHS (2011/65/EU), and WEEE (2012/19/EU).

Mechanical and Electrical Design

• Features an independent synthetic polymer mounting plate providing mechanical fixation and electrical connection.
• Screwless locking system enables easy installation and maintenance.
• Connection terminals support cable cross-sections up to 2.5 mm² for input and output wiring.

Battery Technology and Management

• Utilizes LiFePO4 batteries known for safety and long life.
• Microprocessor-controlled charging manages voltage independently per battery module and adjusts charging based on temperature.
• Charging is minimized to a few minutes daily to reduce energy consumption and extend battery lifespan.
• Includes a thermal safety probe to prevent overheating by limiting charging according to temperature.

Electronics and Energy Efficiency

• Compact electronic circuits with low heat generation.
• Energy efficiency achieved through an electronic transformer combined with microcontroller battery management.
• Use of tantalum polymer capacitors in critical areas enhances electronic durability.

LED Lighting Performance

• Equipped with six high-efficiency LEDs operated below nominal power for longevity.
• Thermal management ensures lifespan exceeding 70,000 hours at L90/B10 standard (90% lumen maintenance, 10% failure rate).
• Maintained operation mode provides constant 200 lumens output when ambient light is below a preset threshold.

Optical Features

• Employs MCRLED micro-structured flat diffusers optimizing luminous performance for various ceiling and wall mounting heights.
• Offers three optical configurations:
• Open area and escape route lighting (EVC) for ceiling mounting.
• Wall-mounted lighting (PRD) for safety point illumination.

Physical Dimensions and Protection Ratings

• Dimensions include sizes such as 225 x 110 mm and others depending on model.
• Protection ratings vary by model: IP43 and IP66 for ingress protection; IK04 and IK10 for impact resistance.
• Suitable for diverse installation environments including interior and exterior without direct solar exposure.

Operation Modes and Features

• Non-maintained (NM): Emergency lighting without permanent power supply.
• Maintained (M): Continuous lighting operation.
• Battery autonomy options: 1h, 1.5h, 2h, and 3h durations.
• Centralized power supply versions available without internal batteries.
• DaisaTest (TCA): Enables luminaire monitoring via control computer to optimize maintenance.
• Autotest (A-TEST): Self-testing of battery, light source, and device status with indicator.
• DALI Operation: Compatible with DALI control units, supports self-testing and status indication.
• Remote Control (T): Allows switching on/off during power outages via remote control.

Photometric Characteristics

• Asymmetric optics optimized for evacuation routes with ceiling mounting heights between 2 and 6 meters.
• Symmetrical optics optimized for anti-panic lighting within the same height range.
• Photometric diagrams demonstrate luminous intensity distribution suitable for emergency lighting applications.

Product Variants and Models

• Multiple model references with varying sizes (e.g., 200x100 mm, 205x205 mm) to suit different installation needs.
• Designed for interior use and exterior use without direct solar exposure.

Key Benefits and Best Practices

• Easy installation and maintenance due to screwless locking and independent polymer plate.
• Long battery life ensured by advanced battery management and thermal safety features.
• Energy-efficient LED technology reduces power consumption and heat generation.
• Flexible optical options allow tailored emergency lighting solutions for diverse architectural requirements.
• Compliance with multiple international standards guarantees safety and regulatory adherence.

Critical Parameters and Limitations

• Maximum cable cross-section for connection terminals is 2.5 mm².
• Battery charging is temperature-dependent, which may slow charging under extreme conditions to prevent damage.
• Maintained light output is limited to 200 lumens under low ambient light conditions.
