ITEM 4 – LED Sign Kits (Retrofit) [Signs] Sign Conversions, Retrofit - UYWU
See General Information for Signs
USE AND INSTALLATION
This category covers retrofit sign conversions consisting of subassemblies or kits intended for field installation in Listed signs. There are several types of sign conversions as specified below.
Scrolling units (motor-operated message assemblies), devices to change the type of illumination ( such as from incandescent to fluorescent), or combinations thereof consist of subassemblies intended for field installation in specific Listed permanently connected electric signs. The conversion identifies the catalog number (or other description) and company name of the sign in which it is intended to be used.
Light-emitting diode (LED) kits consist of the power source, the LEDs and the LED mounting means necessary to change the type of illumination originally contained in the sign to LED illumination. The kit installation instructions specify the type of sign in which the kit is intended to be installed.
These retrofit sign conversions have been investigated to determine that, when used in accordance with the manufacturer's instructions provided with the retrofit device, they do not adversely affect the operation of the complete electric sign.
43
ITEM 4 – LED Sign Kits (Retrofit)
ADDITIONAL INFORMATION
For additional information, see Signs (UXYT) and Electrical Equipment for Use in Ordinary Locations (AALZ).
REQUIREMENTS
The basic standard used to investigate retrofit sign conversions in this category is UL 48, "Electric Signs."
The basic requirements used to investigate retrofit sign conversion LED kits in this category are contained in UL Subject 879A, "Outline of Investigation for LED Kits."
44
UL 879A – SCOPE Par. 1.1.1
1.1.1 This standard covers LED (light emitting diode) kits intended for field installation to retrofit signs already installed in the field and LED kits intended for installation in new signs
Comments:
Should also cover Induction Lighting and Electroluminescent retrofit kits and delete reference to kits for new signs.
46
UL 879A – SCOPE Par. 1.2.1
1.2.1 These LED kits are intended to replace all of the electrical components related to a type of illumination in a sign. For neon signs these components include neon tubes, tube supports, neon supplies, and all secondary wiring from the neon supply. For fluorescent signs these components include fluorescent tubes, lampholders, ballast, and ballast secondary wiring. All types of illumination within a sign must be replaced, unless there are different compartments of a sign for different light sources and they only share the same circuitry at the branch circuit connection point.
47
UL 879A – SCOPE Par. 1.2.1
Comments:
A. Delete last two sentences requiring all light sources to be replaced unless other sources separately enclosed.
B. Revise to add “POWER” - For neon signs these components include neon tubes, tube supports, neon power supplies
C. 1.2.1 is related to specific types is retrofit sign illumination that is limited to neon and fluorescent. This needs to be expanded to include replacement of HID.
D. Revise to read “Retrofit kits include the power supply or transformer, power supply or transformer enclosure, the LEDs, secondary conductors, wire connectors suitable for the voltage, and the LED mounting means.”
E. In 1.2.1 it states that All types of illumination must be replaced. Is this intended to not allow existing components to be used - like power supplies or circuit protection? There are some cases where this equipment can be used again if the evaluation finds it can be reused. Do we want to limit this? If so what is the reasoning behind it?
48
UL 879A – SCOPE Par. 1.2.2
1.2.2 Retrofit kits include the power supply or transformer, power supply or transformer enclosure, the LEDs and the LED mounting means.
Comments:
A. Add reference to HID and electroluminescent and installation instructions.
B. Add “as per NEC Article 600 requirements” at end of sentence.
C. Revise: Retrofit kits include the power supply or transformer, power supply or transformer enclosure, the LEDs,and the LED mounting means all secondary wiring, equipment and primary connection(s) .
49
UL 879A – SCOPE Par. 1.3.2
1.3.2 LEDs, secondary wiring, and LED transformers or supplies may be provided separately.
Comments:
This is a contradiction of what a retrofit Kit is. It is a complete collection of parts for retrofitting an illumination specific sign. This concept has been expressed repeatedly by UL. The practice of the parts being provided separately is the basis for the industries request for a review of 879A.
50
UL 879A – COMPONENTS Par. 2.2
2.2 A component is not required to comply with a specific requirement that:
a) Involves a feature or characteristic not required in the application of the component in the product covered by this standard;
b) Is superseded by a requirement in this standard.
Comments: Revise to read
2.2 A component is not required to comply with an additional requirement not specific to the application a specific requirement that:
.
51
UL 879A – COMPONENTS Par. 2.3
2.3 A component shall be used in accordance with its rating established for the intended conditions of use
Comments: Revise to read
2.3 A component shall be used in accordance with its rating Listing established for the conditions of use..
52
UL 879A GLOSSARY - SECTION 5
Comments:
A. Add definition for retrofit kit.
B. (5.4) – Delete reference to 45 degree box
C. (5.8) – Question on LPS equivalence to Class 2
D. Correct to read 5.11 WEATHERPROOF - See Wet Location, 5.10 5.12.
.
53
UL 879A – POWER SUPPLIES AND TRANSFORMERS Par. 6.1.3
6.1.3 Power supplies and transformers may have more than one Class 2 or LPS output
Comments:
A. What about class1? If it is not mentioned in this section, does that mean it is not allowed?
54
UL 879A – POWER SUPPLIES AND TRANSFORMERS Par. 6.1.3
6.2.1.1 Except for features specified in this standard, power supplies shall comply with the requirements of the Standard for Electric Sign Components, UL 879.
6.3.1 Except for features specified in this standard a transformer shall comply with the requirements of the Standard for Electric Sign Components, UL 879.
Comments:
A. Add reference to NFPA 70
55
UL 879A – LED Units and Modules C of A’s
15.1.2 Tubular LED lamps that are intended to replace fluorescent lamps and use existing lampholders only for mechanical support and are powered by separate supply connections shall comply with:
a) The requirements for tubular lamps in the Standard for Self-Ballasted Lamps and Lamp Adapters, UL 1993; and
15.2.4 Each LED circuit is restricted to Class 2 or LPS limits.
15.2.5 Suitability of electrical enclosure and secondary wiring shall be determined if single circuit power requirements exceed Class 2 or LPS limits.
Comments:
A. Need access to UL 1993 to comment
B. 15.2.4 and 15.2.5 seem to contradict each other. Should there be clarification as to when 15.2.5 is acceptable?
56
UL 879A – Secondary Wiring – Sec 16.2.2
16.2.2 Class 2 wiring methods in accordance with Chapter 725 of the National Electrical Code, ANSI/NFPA 70 shall be used for wiring between the LED unit and remote power units marked Class 2 or LPS.
Comments:
A. Revise to read:
16.2.2 Class 2 wiring methods in accordance with 300, 600.12(C)(1)(2), 600.33, Chapter and 725 of the National Electrical Code, ANSI/NFPA 70, shall be used for wiring between the LED unit and remote power units marked Class 2 or LPS.
57
UL 879A – Secondary Wiring – Sec 16.3.3
Comments:
A. Revise to read:
16.3.3 Class 2 circuits operating at over 15 Vrms ac or 30 Vdc or 12.4 Vdc interrupted at 10 to 200 Hz in a wet location shall use Class Chapter 3 wiring methods. These wiring methods are specified in Chapter 3 725 of the National Electrical Code, ANSI/NFPA 70. Examples include PLTC cable marked "Sunlight Resistant" or "Sun Res", SJTW or SW cord may also be used. Suitable rain tight fittings are required to keep water from entering the LED unit or the remote power unit.
58
UL 879A – Supplement – SA 11.1
SA11.1 Accessible non-current-carrying metal parts that could be energized from within and where the voltage is greater than 150 V shall be bonded to ground or be made inaccessible.
Comments:
We are dealing with Class 2 or your equivalent LPS and there is no safety reason to allow accessible non-current carrying parts with a potential line current above 30V to not be connected to an equipment grounding conductor per the NEC
59
UL 879A – General
Comments:
How will the Type L labeling be addressed? Will there be a new requirement for a retrofitted sign capability? I know this requirement exists for rebuilt signs.
60
UL 879A – General
