China Emergency Light – Emergency Light Control Emergency: 7 Points
China Emergency Light indicates that emergency lighting can be safely and reliably controlled economically to save energy and meet design requirements and code compliance with these guidelines:

  1. Avoid installing the normal control emergency circuit on it as much as possible. Instead, use the device emergency lighting that will be switched to combine lighting and automatic switching with normal conditions.

  Emergency lighting when power is off.

  2. The control device must be installed in an emergency (such as a dimmer) circuit to ensure that the device will be completely bypassed in the power situation.

  3. Use only these product designs and UL lists emergency circuits that use these applications. While components not listed may be installed with features similar to approved transfer switches or ALCR, the lack of proper listing exists for many risks that apply to designers and owners. Signator may not be willing to sign the project

  Use an unlabeled device. Because components may not be affected for rigorous testing, they may fail critically. In addition, insurance adjusters can cite non-listed equipment as a reason for delay or delay to reduce claims related to emergency situations.

  4. Monitor the normal power circuit on the branch close to the actual load, not just the main power supply through a, the system will respond to local failures and failures, providing maximum utility and addressing the branch-related code requirements circuitry.

  5. Review technical specifications. In addition to the appropriate UL list, the equipment should be designed and constructed for emergency circuits to minimize failure and still provide protection in case of failure. Avoid the use of devices that are easily fused to fail when selecting devices. Extend relay life with zero-crossing device switching technology. Understand the normally closed relays for emergency control so that they fail, they will fail to turn on the lights due to an emergency.

  6. To protect maintenance personnel, select a device with clear visual indications to indicate an emergency and

  Normal strength. Also, make sure all equipment has an appropriate warning label on the emergency circuit.

  7. Design emergency circuits in consideration of test requirements. Code requirements to test emergency systems

  Regularly (usually every 30 days, there is a longer interval between extended tests) and records are saved for inspection of AHJ. The specified product should provide convenient testing options. Remote switch is not convenient if the device will be desirable
