  How do I take care of this?
  Your BBB is requesting a written response to this complaint within the next 7 calendar days.  Your prompt and professional response greatly enhances the chance for a successful resolution and will further your reputation as a BBB Accredited Business.  If you received this complaint via email, the fastest and easiest way to view and respond is to the simply click on the “Respond to this Complaint”, link located on the left.  All responses will be copied to the complainant. 
  
  

  If you received this complaint via Postal Mail, you may respond online using the link below or respond by mail using the address above.
  To access/respond to this complaint online:
  Go to: ****************
  Enter the following code: **************

  What should I include in my response?
  Please provide an explanation of the events from your perspective and/or a concrete plan for how to work toward a resolution. Remember that the more factual information we have about the case, the easier it is for all parties to develop a full understanding of the situation. 
   
  Please understand that the complaint content and your response may be publicly posted on the BBB web site (BBB reserves the right to not post in accordance with BBB policy). Please do not include any information that personally identifies your customer. By submitting your response, you are representing that it is a truthful account of your experience with this consumer.

  What will happen if I do not submit a response and what can I expect to happen next?
  If you do not respond promptly to this complaint, it may be closed as Unanswered.  This may result in a substantially lower rating with BBB, which could adversely influence potential customers. Once we receive your response, we will forward it to your customer and ask them to tell us in writing whether your response resolves their concerns.  If they continue to express dissatisfaction, the case will be reviewed by BBB staff to determine if the remaining concerns warrant an additional response.  The overall standard applied in the review process is: Did the company act in good faith, and do everything that could be reasonably expected, or is responsible for, to resolve the issue?
  
  We look forward to helping you and your customer work toward an amicable resolution.

  Dear Aryeh ******:
  
  Thank you for contacting the Better Business Bureau. This message is in regard to your complaint submitted on 9/6/2023 against Universal Security Instruments.  Your complaint was assigned ID ********* 
  
  Now that I have filed, what is the next step?
  We have forwarded your complaint to the business for their response. We have asked the business to reply promptly, but some disputes may take longer than others to conclude.  Please be patient as we work to ensure that your concerns are addressed. 
  
  What if I do not agree with the response from the business?
  It is important for both parties to maintain realistic expectations and respond in a professional, fair and courteous manner.  Our goal is for you and the business to be able to work towards an amicable solution. Should this prove difficult, we may offer you and the business the opportunity to participate in binding arbitration.  More information about these options can be found at www.bbb.org
  
  What happens if a business does not respond?
  BBB will make every effort to obtain a response from the business, but some businesses simply do not ever contact us.  BBB is not an enforcement agency. We cannot force a business to respond. However, failure to do so may result in a negative impact on their BBB rating, which may drive away future customers. BBB can also refer you to other agencies that may be able to assist you, depending on the specific nature of your complaint. 
  
  Feedback from consumers is vital to BBB. We appreciate your willingness to report this information to us. We look forward to helping you and the business work toward a resolution. Please do not hesitate to contact us with any additional questions or concerns.

  I have been trying to contact this company regarding doing a warranty exchange for 2 of my smoke detectors that went bad and they completely refuse to contact me back. I have called and left voice messages and have emailed them with no reply. The model number for the 2 smoke detectors is mdscn111 and the date manufactured is July 21st 2020. They dont need replaced until 2027 and already dont work. The carbon monoxide detector endlessly goes off and the fire department has been by for testing and there is no detection of carbon monoxide at all but just faulty smoke detectors. I would like to replace these ASAP since its dangerous not to have them installed but this company refuses to reach back out to help me. Im assuming all they care about is sales and not helping me with a warranty exchange.

  We have not received a voice mail message or an email from this customer. We are requesting a copy of the alleged email that was sent to investigate this claim. If we had received a voice mail or an email, we would have responded as quickly as possible.

  Please see our response regarding warranty replacement below. 

  (2) MDSCN111, 2020JUL21 - False Alarming at Random

  Please make sure you are properly resetting the units by pressing and holding the test button for over 10 full seconds before releasing it. You must count slowly for ***** seconds to make sure that reset has time to take place. Itll be an audible reset thatll go through the interconnection,which will reset all your hardwired units at the same time if theyre all our brand. This reset is best done while connected to ********* However, it may be done individually when unplugged with an approved battery installed.
  
  Remember to always turn off the circuit breaker to the units before removing or installing a unit. This will avoid a break in the interconnection which causes nuisance alarms, beeping, chirping, or shorting out the unit by the live voltage or shock to your person. While the breaker is off, check all the wiring at the wire nuts to make sure everything is still securely connected. Once the breaker is turned back on all the hardwired units will equally interconnect if theyre all the same brand, even if one or more have been removed.
  
  Always use an approved 9-volt battery listed in the manual, such as an Energizer 522 or a Duracell MN1604. The battery drawer will not be able to close if the battery is not properly positioned. An unapproved battery will cause a chirp or beep that cannot be resolved by a proper reset.However, it will not cause an alarm.
  
  Please also make sure the unit is clear of any dust or debris. You may use a vacuum to remove any loose debris from inside the unit by going around the perimeter and over the vents.
  
  If the two units will not properly function after all troubleshooting efforts have been taken, they may be replaced under the 7-year limited warranty. You may send them without the batteries to USI Electric at ******************************************************************************************************* *******.
  
  Please be sure to include a note with your name, phone number and return shipping address inside the package, along with an $18.00 check or money order made payable to USI Electric. This covers the current postage and handling cost of two MDSCN111 replacement units. The units themselves will be replaced at no cost under the limited warranty as noted on the last page of the manual.         
  
  Do not use tape or staples inside your package as it will only slow the process of your return. Once we receive the contents of your package the replacement order will be processed as quickly as possible.
  
  I have attached a copy of the MDSCN111 manual for your review and records. Please make sure to follow all placement and maintenance instructions to avoid nuisance issues, contamination, and voiding the warranty.
