Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang DUAL-LITE dari 3G Electric.
What UL standards do DUAL-LITE emergency lights comply with?
DUAL-LITE emergency lights, such as the EZ-2L, are listed to UL 924, which covers emergency lighting and power equipment. This standard ensures the units provide adequate illumination for egress paths during power loss, and includes requirements for battery charging, lamp operation, and environmental ratings. Always verify the specific model's listing for your jurisdiction.
Are DUAL-LITE exit signs available with self-diagnostics?
Yes, DUAL-LITE offers exit signs with self-diagnostics, such as the EVEUGWEI and EVEURWEI models. These units automatically test battery and lamp function per NFPA 101 requirements, reducing manual inspection frequency. Models without self-diagnostics, like the EVEURW, are also available for applications where manual testing is acceptable.
Can DUAL-LITE remote heads be used with any emergency light?
DUAL-LITE remote heads, like the EVR2, are designed for compatibility with specific models, such as the EV4D and EVC-D4 series. They operate at 4.8 V and are adjustable for directional lighting. For other DUAL-LITE units, check the product specifications for remote capability; some models, like the Dynamo DYN12I-4X-06L, support remote heads, while others do not.
What is the difference between DUAL-LITE EZ-2 and Dynamo series emergency lights?
The EZ-2 series, such as the EZ-2L, is a plastic emergency light rated for damp locations, with 1 W LED lamp wattage and 1 W emergency wattage, suitable for indoor use. The Dynamo series, like the DYN12I-4X-06L, is rated for wet locations, has 12 W lamp wattage and 24 W emergency wattage, and supports remote heads. The Dynamo is designed for harsher environments and higher light output.
What battery technology do DUAL-LITE exit signs with emergency backup use?
DUAL-LITE exit signs with emergency backup, such as the EVCURW and EVCURWD4, use lithium iron phosphate (LiFePO4) batteries. This chemistry offers longer life and stable performance compared to sealed lead-acid batteries, and is commonly used in LED emergency lighting for reduced maintenance. Always confirm battery type in the product datasheet.
