Emergency Lights, Nickel Metal Hydride (NiMH), Self-Testing, Title 20, NEMA4X Rated, Wet Location Products (2 items)

An emergency light is a lighting device with a battery backup that switches on automatically when a building experiences a power outage. Emergency lights are standard in commercial and high occupancy residential buildings, such as college dormitories. Most building codes require emergency lighting be installed in older buildings as well.

A nickel metal hydride battery, abbreviated NiMH or Ni–MH, is a type of rechargeable battery. A NiMH battery can have two to three times the capacity of an equivalent size NiCd, and its energy density can approach that of a lithium-ion battery.

This feature may be added to many exit sign and emergency light fixtures, the SDT feature prolongs battery life, and reduced man hours required OSHA tests. Self testing diagnostic automatically executes a 15 minute test every 30 days and runs a 90 minutes test once per year. The major reasons batteries typically fail is because they remain dormant for long periods of time. With the SDT feature automatically simulates a full discharge and full recharge to keep the batteries in peak performance. If any problems arise during this testing process it will report them through the user interface. This benefit drastically reduces man hours required by OSHA to manually perform the tests.

Title 20 is part of the CEC's Appliance Efficiency Regulation and California Code of Regulations that requires manufacturer certification of "self-contained” lighting control devices in California.

 

"Self-contained” lighting control devices are defined as discrete lighting control devices that can perform their designed function without the requirement of being connected to additional devices.

 

Common devices that may fall under the category of "Self-contained” include:

NEMA rated enclosures are intended for indoor or outdoor use primarily to provide a degree of protection against the entry of water during prolonged submersion at a limited depth. NEMA 12 enclosures are designed to prevent the ingress of dust, water, and oil.

Wet Location emergency lights and exit signs are weatherproof and designed to be used in outdoor environments, as well as indoor locations that are exposed to water and moisture. Wet location emergency lights and exit signs are extremely durable and long-lasting.
