Door Monitor for NYC Compliance

An out-of-the-box solution to match voltage variability

A newcomer to the industry, Argus Elevator has a practical solution for those seeking to comply with stringent New York City (NYC) elevator building codes. The company says it can bring any elevator system into compliance with NYC Building Code 3.10.12 (Appendix K3) with minimal effort and resources compared to other options on the market. The Argus Elevator Door Monitor does not require specific hardware configuration to match the variability in voltage levels of the different signals that need to be monitored. The configuration is accomplished via a built-in graphical user interface, which can be configured by the company before shipment or by the customer after reception.

The patent-pending design is certified to ASME A17.5/CSA B44.1. The unit’s built-in graphical user interface helps configure each input without a hitch, although Argus can set it up prior to shipment if desired. It has a color display for easy wiring verification and uses timestamps to record the eight most recent events. It is designed for ruggedness and is covered by a lifetime warranty.

Each input can monitor voltage levels of 12-300 VAC or VDC and be configured for positive logic (active high) or negative logic (active low) (Figure 1). Another significant feature of the product is its compact size, only 4.1 X 3.3 X 2.3 in. It supports DIN-rail and wall mounting and is designed to fit snugly inside the elevator controller, which Argus says can save a sizeable portion of installation time. Power consumption is less than 3 W.

No hardware configuration is required. Argus adds that, unlike competing devices that rely on hardware logic (usually in the form of relays), its product is firmware based. This means that, in the case of future regulations changes, the device will be brought up to compliance through software upgrades it calls “seamless” via a PC and Argus-provided serial cable. An update that adds Rope Gripper® functionality by utilizing spare inputs and outputs is already in the works.

Argus was founded in August 2018 in Marietta, Georgia, by Omar Gil. Gil, who serves as president, has 10 years of experience in leading the design of electronics and firmware for numerous industries, including automobile, gambling, industrial controls and medical.
