How to Become DLM Compliant
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.
Options:
1. Parameter Activation
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. Firmware Upgrade
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.
If Hardware is Not in Place:
3. Controller Upgrade
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
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. DLM Device
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.
