In an emergency, life safety is the number one priority. By using central lighting inverters to power existing indoor and outdoor luminaires in lieu of self-contained emergency lights, occupants are more likely to evacuate to a public way in a safe and orderly fashion. Central lighting inverters not only make occupants feel more at ease during a crisis, but they also maintain the architectural integrity of the building and typically yield the lowest total cost of ownership during normal operation. Greater value – increased safety!

Life Safety Code
When interior or exterior lighting extinguishes due to an interruption in the normal power supply, the Life Safety Code (NFPA 101) requires egress pathway illumination, which can be provided by a Dual-Lite inverter system. This requirement includes illuminating both the path of egress from inside the building to the nearest exit point and from outside the building to the “public way.”

According to the Life Safety Code, emergency pathway illumination is required for:

  • Stairs
  • Aisles
  • Corridors
  • Ramps
  • Walkways
  • Parking lots
  • Escalators
  • Exit passages
  • Outdoor pathways

When compared to other emergency lighting solutions, Central Lighting Inverters are:

  • Safer than other emergency lighting solutions because they typically provide full lumen output of the luminaire resulting in higher emergency light levels.
  • Are more reliable because they are centrally located for easy maintenance and have the capability to email test results or alarm conditions to maintenance personnel .
  • Offer greater value by using existing light sources, which maintains architectural design.
    Dual-Lite’s central lighting inverter product line offers both interruptible and non-interruptible emergency AC power systems in single- and three-phase configurations.

Advantages of a Central Lighting Inverter System

Full Lumen Output
Occupants feel more at ease and are less likely to panic when emergency lighting is provided by existing luminaires. Central lighting inverters power designated luminaires to full lumen output during a power outage ensuring a bright, evenly illuminated path of egress in emergency situations.

Aesthetics
Using existing luminaires allows occupants to enjoy the original architectural intent and integrity while simultaneously satisfying life safety requirements.

Ease of Installation
In most installations a single central lighting inverter will provide code required power to the emergency lighting vs multiple fluorescent battery packs or unit equipment. This reduces the amount of time and labor required for initial installation.

Ease of Maintenance
With a centrally located inverter system there is only one location for maintenance vs unit equipment which is located throughout the building, reducing maintenance time and labor costs.

HID Compatibility
Luminaires using HID lamp technology are often selected for a given lighting system because of their energy efficiency, long life and tolerance to high or low ambient temperatures. However, HID lamps are susceptible to voltage drops and have long re-strike times that could exceed life safety code requirements. Where HID luminaires are in use or being considered, an uninterruptible central lighting inverter is the ideal choice as an emergency AC power supply, even when an engine generator set is installed by code requirement. An uninterruptible power supply ensures voltage sensitive loads, such as HID lamps, will operate normally as power transitions from utility power to emergency battery power to emergency generator power and back to normal utility power.

Outdoor Applications
In the absence of lighting due to an interruption in the normal power supply, the Life Safety Code calls for illumination of an egress pathway to safely guide building occupants to a “public way.” Some Authorities Having Jurisdiction (AHJs) will interpret a “public way” to include luminaires in outdoor applications. Inverters can remain located inside the building so cold or wet conditions that can impact performance, cost or life of the product are eliminated.

Area of Coverage
The ability to generate the required level of illumination in large venues, such as stadiums or gymnasiums, is beyond the capability of most emergency lighting unit equipment. A properly sized central lighting inverter powering existing fixtures at full light output is the logical choice for these applications.

Auxiliary Critical Loads
In addition to providing emergency AC power for lighting loads, a central lighting inverter can also be used to provide emergency power for other critical equipment such as:

  • Fire detection and protection equipment
  • Directional egress systems
  • Building management systems
  • Automated door mechanisms
  • Climate control systems
  • Patient care support functions
  • Security systems
  • Communications equipment

Total Cost of Ownership
Dual-Lite realizes the initial price of an emergency lighting system is only one consideration when evaluating the total cost of ownership when comparing a centralized vs a decentralized emergency lighting system. Energy costs to operate the unit and annual maintenance expenses can significantly add to the total cost of ownership. Incorporating a central lighting inverter into your emergency lighting system will typically reduce your operating and maintenance costs to yield the lowest overall total cost of ownership. By incorporating energy efficient designs and intuitive interfaces with the latest in remote communications technology, Dual-Lite central lighting inverters are designed to lower the total cost of ownership even further.

LiteGear Compact Single-Phase Inverters
LiteGear Compact Single-Phase Inverters
Available with 100VA or 250VA capacity, Dual-Lite’s LiteGear® compact central lighting inverters provide emergency AC power to existing indoor and outdoor lighting fixtures. The LiteGear® series is compatible with incandescent, compact fluorescent, linear fluorescent and LED lamped fixtures.

Features and Benefits:

  • AC LOCKOUT – Prevents battery damage by shutting off DC battery power prior to AC power being supplied during installation.
  • BROWNOUT PROTECTION – Protects loads from low AC line voltage by automatically transferring the inverter to emergency mode to provide full output power.
  • LOW VOLTAGE DISCONNECT – Protects the batteries from damaging ‘deep-discharge’ conditions during prolonged power outages.
  • MULTIPLE MOUNTING OPTIONS – The compact size of LiteGear® inverters allows the LG2 to be surface wall mounted while the LG1 may be surface wall, recessed wall, or recessed into a T-Grid ceiling.
  • LED LAMP COMPATIBILITY – LiteGear® inverters are typically more cost effective than decentralized battery packs at providing emergency power to a luminaire, especially luminaires using today’s LED lamp technology.
  • GENERATION I STATUS & CONTROL INTERFACE – Two multipurpose LED indicators provide a simple, intuitive interface to notify the user of operating status.
