Attention Houston Building Managers & Elevator Contractors – are you ready to meet ???????? ????????.?? ?????????????????? ???????????????? ?????????? ??????????????????? ?? By December 31, 2026, every elevator hoistway located within the 100-year or 500-year floodplain (and buildings with elevators that travel below grade level) must have a pit flood protection system in place that does the following three things: 1?? Takes the elevator to an approved floor where both the cab and counterweight are safe and removes the elevator from service. 2?? Provides visual or audible notification to building management. 3?? Can only be returned to service by a Texas-licensed elevator contractor. Our comprehensive, universal solution—featuring the ????????-?????? ?????? ?????????? ?????????????????? paired with the ????????-?????? ?????? ?????????? ?????????? ???????????? is the quickest and most cost-effective way to ensure compliance with 3003.4: ?????????????????? ??????????????????????????:? Seamlessly integrates with all microprocessor-based and relay-based controllers from Dover, EC, Fujitec, KONE, MCE, OTIS, Schindler, ThyssenKrupp (TK), Virginia Controls, Westinghouse, and more. ????/?? ???????????????????? & ?????????????????? ????????????????: The A100-PFS detects as little as 1 inch of water in the pit and triggers the system to automatically move the elevator to a predetermined safe floor above the floodplain, open its doors for passenger exit, and disable further operation until manually reset by a licensed Texas elevator contractor. ?????????? ???????????? ????????????????????: Mitigates costly repairs and operational downtime caused by heavy rainfall, hurricanes, tropical storms, and other flooding events.

???????? ??: ?????? ???? ???????????? ?????? ???????????????????? This is the sixth and final installment in our six-part series on door lock monitoring (DLM). In this series, we addressed some of the most common questions we receive about DLM. If you still have additional questions after reading, we’d be happy to schedule time to discuss them further. In our previous post, we explored how to tell if an elevator already has DLM implemented. Today’s post is on what to do if don’t have DLM implemented and how to become compliant. ??????????????: ??????? 1?? ?????????????????? ???????????????????? In our last post, we discussed how controllers from the early 2000s may have the hardware for door lock monitoring, but the functionality may not be activated. In these cases, it might be as simple as activating a parameter. After confirming this with your controller company, they can guide you through the steps to enable it. 2?? ???????????????? ?????????????? Similarly, your elevator may have the proper hardware in place, but it might require a firmware upgrade to enable door lock monitoring. Once confirmed with your controller company, they will provide instructions on how to perform the upgrade. ???? ???????????????? ???? ?????? ???? ??????????: 3?? ???????????????????? ?????????????? Replacing the controller is a more expensive option than adding a stand-alone DLM device. If a controller upgrade is only being done to add DLM functionality, it might not make sense financially. However, if the controller is near the end of its life, causing frequent issues, or if the customer wants to add additional functionality, a controller replacement could be the right solution. A new controller will come equipped with DLM functionality. 4?? ?????????????????????????? Modernization solely for achieving DLM functionality is rarely a cost-effective choice, either. However, there comes a time in an elevator’s life when the cost of replacing components and keeping it operational exceeds the cost of full modernization. In such cases, modernization might be the best option. 5?? ?????? ???????????? If the above options are not cost-effective or feasible, a stand-alone DLM device offers an excellent solution. For example, the Argus A100-DLM Elevator Door Lock Monitor provides door lock monitoring functionality for any controller and is compact enough to fit within the existing enclosure. This is a quick and cost-effective way to bring any elevator into compliance. ?????????????? ??????????????: This is the final post in our series. We hope you found it informative and helpful.

???????? ??: ?????? ???? ???????? ???? ???????? ???????????????? ?????????????? ?????? ?????? ??????????????????????? - ?????????? ?? & ???? This is the fifth installment in a six-part series on door lock monitoring (DLM). In this series, we’re addressing some of the most common questions we receive about DLM. If you still have additional questions after reading, we’d be happy to schedule time to discuss them further. In our last post, we looked at the first two ways to determine if your elevator has door lock monitoring implemented. In today’s post, we will look at the third and fourth ways. ?3?? ???????? ?????? ???????????????? ?????? ?????? ?????????????????????????? As discussed in Post 2 of this series, elevators have two main requirements: a Door Closing Restriction and a Car Motion Restriction. Controllers that implement DLM enforce both of these requirements, so to determine if an elevator has DLM implemented, we can focus on testing the easier and safer of the two: the Door Closing Restriction. To test the Door Closing Restriction, we provide the following steps with every set of revised engineering prints: ???????? ?? - ???????? ???????????? ???????? A. With the car parked at a floor and with the car doors and hall doors fully open, close the Gate Switch contacts and place a call to a floor different than the current one Result: The car will not close its doors and the car will not move ???????? ?? - ???????? ???????????????????? ????????

This is the definitive step we always recommend. By contacting the controller company, they can confirm whether the elevator has DLM in place or if it can be easily upgraded through a parameter activation or firmware update. We hope you learned something new today and enjoyed reading our fifth post in this series. Keep a lookout for our next installment in a few days. In the next post, we will cover the ways to make an elevator compliant for DLM. #ArgusElevator #Elevator #Elevators #ElevatorIndustry #ElevatorSafety

???????? ??: ?????? ???? ???????? ???? ???????? ???????????????? ?????????????? ?????? ?????? ??????????????????????? - ?????????? ??& ?? ?? This is the fourth installment in a six-part series on door lock monitoring (DLM). In this series, we're addressing some of the most common questions we receive about DLM. If you still have additional questions after reading, we’d be happy to schedule time to discuss them further. In our last post, we explored the reasons for door lock monitoring. In this installment, we’ll cover two steps to see if an elevator has DLM implemented. Steps three and four will be discussed in the next installment. This post is intended for OEMs and independent contractors. If you are a building owner or maintenance professional, we recommend contacting your elevator contractor or consultant to perform an on-site compliance assessment for door lock monitoring. 1?? ???????? ?????? ?????????? If you're unsure whether DLM is implemented in an elevator, a good starting point is to examine the hardware or wiring. DLM requires monitoring the door locks and gate switches, so these must be measured independently. ???? ??????:??If the gate switches and door interlocks are wired in series without a way to measure them independently, it’s a clear sign that DLM is not in place. ?????????????????? ??????: If the gate switches and door locks are wired independently, there’s additional circuitry on the schematics to isolate portions of the circuit, or one side of the gate switches and door locks is labeled as a monitor input to the controller, these are signs that DLM may be in place. Important Note: Even if the wiring and circuitry for DLM are present, this doesn’t guarantee it is implemented. The controller may require activation of this functionality via parameter settings or a firmware upgrade. 2?? ?????????? ?????? ???????????????????????? ???????? ???????????? ????????: DLM was first adopted in the 2000 edition of ASME A17.1. Elevators installed before 2000 typically lack the necessary hardware for DLM. ?????????? ??????????: Elevators installed in this period may have DLM-related hardware, as controllers were being designed to comply with the 2000 code. However, since not all states mandated DLM, it often requires firmware updates or parameter activation to enable the feature. ??????????: Elevators installed during this time are likely to have both the hardware and firmware for DLM, with parameters activated. While it’s probable that DLM is active, you should confirm this with the controller manufacturer to be certain. ???????? ?????????? ?????? ????????????: If your state implemented DLM for new installations before requiring it for existing elevators, check the specific requirement date. If your elevator was installed after this date, it’s very likely that DLM is in place. We hope you learned something new today and enjoyed reading our fourth post in this series. In the next post, we will cover steps 3 and 4.

???????? ??: ???????????? ???????????????????????????? & ?????????????????? – ?????? ?????? ???????? ???????? ???????????????????? ?????????? ???? ?????? ????????? ?? This is the third installment in a six-part series on door lock monitoring (DLM). In this series, we’re addressing some of the most common questions we receive about DLM. If you still have additional questions after reading, we’d be happy to schedule time to discuss them further. In our last post, we explored the two main requirements of door lock monitoring. Today, we’ll focus on the practical safety considerations and provide links to some of the accidents that led to door lock monitoring being implemented. Elevators are designed to move only when their doors are closed. However, like any complex piece of equipment with many moving parts, elevators experience wear and tear over time. This includes the door locks and gate switches, which, if worn or damaged, may incorrectly report their status—open when they are closed or vice versa. Additionally, actions taken by mechanics during troubleshooting or repair, if not properly undone, can cause gate switches or door locks to give false readings. This is where door lock monitoring (DLM) adds an extra layer of safety. DLM improves elevator safety by double-checking all sensors against each other and comparing them to the door's open and closed limits. It ensures that an elevator cannot move if the doors are open and verifies that the door locks and gate switches are functioning correctly, allowing the system to accurately detect whether the doors are open or closed. By doing so, DLM helps prevent horrific accidents. Without door lock monitoring, an elevator could begin moving with its doors open, because the controller mistakenly believes the doors are closed. This can result in severe injury or death if a passenger becomes trapped between the car and the floor as the elevator moves unexpectedly. Although rare, accidents caused by elevators moving with open doors occurred in the absence of Door Lock Monitoring, often making the news due to the resulting fatalities: https://lnkd.in/dptvWYFd https://lnkd.in/dKY4hqQ4 https://lnkd.in/dmeDAyQ2 Thankfully, as Door Lock Monitoring is implemented in additional jurisdictions, these accidents can be prevented from occurring in the future. As more states adopt this critical safety feature, Argus is looking forward to partnering with OEMs and independent contractors to ensure these accidents become a thing of the past. While elevator accidents are never a pleasant topic, we hope this post has helped you understand the importance of door lock monitoring. Be sure to check back for our next installment in a few days. In the next post, we’ll explain how to determine whether an elevator already has DLM implemented. #ArgusElevator #Elevator #Elevators #ElevatorIndustry #ElevatorSafety

???????? ??: ???????? ?????? ?????? ?? ???????? ???????????????????????? ???? ???????? ???????? ????????????????????? ?? This is the second installment in a six-part series on door lock monitoring (DLM). In this series, we’re addressing some of the most common questions we receive about DLM. If you still have additional questions after reading, we’d be happy to schedule time to discuss them further. In our last post, we explored the origin of the term "Door Lock Monitoring." Today, we’ll dive into the two main requirements for door lock monitoring as outlined in the code. Let’s take a closer look: From ASME A17.3 Section 3.10.12: “Means shall be provided to monitor the position of power operated car doors that are mechanically coupled with the landing doors while the car is in the landing zone, in order (a) to prevent automatic operation of the car if the car door is not closed [see 3.4.2(c)], regardless of whether the portion of the circuits incorporating the car door contact or the interlock contact of the landing door coupled with the car door, or both, are closed or open, except as permitted in 3.10.7 (b) to prevent the power closing of the doors during automatic operation if the car door is fully open and any of the following conditions exist: […]” From this section of code, we get the two main requirements: 1?? ?????????????????????? #??: ?????? ???????????? ?????????????????????? This requirement comes from section (a) to?“prevent the automatic operation of the car if the car door is not closed”.?In other words, the elevator must not leave the floor if the car doors are not physically closed, regardless of the status of the door locks and the gate switches. This implies that something additional must be monitored to get the door closed information. This is usually accomplished by monitoring the door closed limit. 2?? ?????????????????????? #??: ???????? ?????????????? ?????????????????????? We touched on this requirement in our last post when looking at where the name “Door Lock Monitoring” came from. Requirement #2 also comes from section (b) of the code, “to prevent the power closing of the doors during automatic operation if the car door is fully open and any of the following conditions exist.”??Summarizing the conditions it describes, the elevator must stay with the door fully open indefinitely if while the car doors are fully opened the gate switch (car door contact) or the door lock circuity, or both, are shorted or bypassed. In total, this gives us two requirements, a Car Motion Restriction and a Door Closing Restriction. Combined, they make up Door Lock Monitoring. We hope you learned something new today and enjoyed reading our second post in this series. Keep a lookout for our next installment in a few days. In the next post, we will cover the reason for door lock monitoring. #ArgusElevator #Elevator #Elevators #ElevatorIndustry #ElevatorSafety

???????? ??: ???????? ???? ???????? ???????? ???????????????????? (??????)? ?? This is the first installment in a six-part series on door lock monitoring (DLM). In this series, we'll address some of the most common questions we receive about DLM. If you still have additional questions after reading, we'd be happy to schedule time to discuss them further. Where does the phrase "???????? ???????? ????????????????????" come from? The phrase "???????? ???????? ????????????????????" does not appear anywhere in the code—it does not exist. Instead, door lock monitoring, abbreviated as "DLM," is the nickname given to the functionality described in ASME A17.1 Safety Code for [New] Elevators and Escalators in Section 2.26.5 and ASME A17.3 Safety Code for Existing Elevators and Escalators in Section 3.10.12 The DLM functionality is described in the code as a "System to Monitor and Prevent Automatic Operation of the Elevator with Faulty Door Circuits"—that's a mouthful. It's too long to remember and too many words to say easily. People needed a shorter name and a better way of describing it. But where did the phrase "???????? ???????? ????????????????????" come from? Under the code, the elevator must follow two sets of requirements for DLM functionality. The name "???????? ???????? ????????????????????" comes from the second set of requirements: From ASME 17.1 Section 2.26.5: "(b) prevent the power closing of the doors during automatic operation if the car door is fully open and any combination of the following conditions exist: (1) the car door closed detection means has detected the closed position or the car door interlock detection means has detected the closed and locked position (2) the door locked detection means of the landing door that is coupled to the opened car door has detected the closed and locked position, except as required in 2.27.3.3.9 (3) the portions of the circuits incorporating the closed detection means or door locked detection means of the car door or landing door that is coupled to the opened car door are bypassed." In other words, a key portion of this code ensures that the door locks are monitored to ensure they are not shorted, bypassed, worn out, or malfunctioning. While this is not 100% of the code's requirements, it is enough to merit the phrase "???????? ???????? ????????????????????" as a nickname. We hope you learned something new today and enjoyed reading our first post in this series. Keep an eye out for our next installment in a few days. In the next post, we will cover the two main sections of the Door Lock Monitoring code. #ArgusElevator #Elevator #Elevators #ElevatorIndustry #ElevatorSafety
