Wi-Fi Exclusive Warning Light Anywhere, Warning Girl-chan [DN-1600W]

ISA Corporation (abbreviated as ISA, located in Shinjuku, Tokyo, President: Koji Yanagihara) will launch the USB bus-powered warning light "Keiko-chan 7UX" on January 10, 2023. The "Keiko-chan 7UX" has been developed as a successor to the three-light model "Keiko-chan 4UX," which was discontinued in August 2022, in response to the long-awaited requests from repeat customers. This popular warning light allows for easy power supply and control via a USB cable, maintaining the basic functions of the 4UX, while the 7UX introduces two new interface options: a USB-only type (DN-1770UX) and a USB/contact input (DI) connection type (DN-1780UX). Both models can be controlled as external commands using a dedicated command tool for Windows, allowing for operation through command prompts, batch files, or applications. Additionally, control can be performed from Linux through device files, enabling users to notify workers and those nearby of "status" using lamps or buzzers on production lines, or to alert of "abnormal conditions" in server rooms in combination with temperature sensors, thus assisting users in their "awareness."

The DN-1600W series, which specializes the interface for Wi-Fi-only functionality, allows for the easy construction of warning and alarm systems in a Wi-Fi environment without the need for LAN installation. It can be used in various locations such as offices, server rooms, medical and caregiving sites, as well as in conference rooms and management offices where personnel are not always present. Operating as a Wi-Fi client, it lights up or flashes lamps based on commands sent via applications (HTTP, MQTT) and activates the built-in buzzer to quickly inform surrounding workers and stakeholders of the "status." The newly announced DN-1600WD is a model equipped with DI (dry contact signal input) functionality, which has been added to the already available DN-1600W. It directly controls lamps and buzzers from external device contact signals. Many devices and sensors can output state changes as contact signals, and by connecting this signal to the contact input terminals of the DN-1600WD, it can easily be added as a reporting device. For example, it can notify of "state changes (abnormalities in equipment or temperature, intrusion of individuals, etc.)" when combined with motion sensors, security cameras, temperature sensors, or door sensors.

ISAI Corporation has developed a compact, palm-sized warning light called "Doko Demo Keiko-chan," which takes into account the changes in lifestyle such as "recent work styles" and "new living standards" from the Keiko-chan series. Following the USB-compatible model, the first Wi-Fi-only model, "DN-1600W," will be available for sale starting December 9, 2020. This warning light works in conjunction with applications and service programs on PCs and servers, combining buzzer sounds and lamp flashing via Wi-Fi to quickly inform surrounding workers and stakeholders of the "status." For example, when linked with Meru Maru-kun, it will notify the Doko Demo Keiko-chan installed on the same network with light and sound when a specific important email that should not be missed is received. It contributes to "awareness" in various settings such as offices, schools, tutoring centers, and commercial facilities.
