Quickly alerting colleagues to the risks of gas poisoning and oxygen deficiency" "Functionality expansion of the gas detection remote monitoring system through a software update.

HERUTU ELECTRONICS CORPORATION

Hertz Electronics Co., Ltd. will provide a software update to expand the functionality of the "En-Guard(R)" series "Remote Monitoring System for Gas Detection," which ensures the safety of workers operating in hazardous environments, starting September 25, 2025. The "Remote Monitoring System for Gas Detection" quickly alerts nearby workers and supervisors in distant locations when gas detectors manufactured by RIKEN KEIKI Co., Ltd. (portable gas monitors "GX-3R Pro," "CO-04BT(C-)," "CX-04BT," and the hazardous gas detector for manhole and pit work "GX-2100") detect the risks of gas poisoning or oxygen deficiency, thereby protecting worker safety. This software update will add three features to expand the means and range of transmitting alarms (gas alarms, man-down alarms, panic alarms, etc.) triggered by the gas detectors to distant colleagues: 1. Lighting alarm lights located at a distance when an alarm is triggered. 2. Acquiring alarm information via Web API. 3. Extending the wireless transmission distance of alarms (increasing the number of relay devices that can be introduced from a maximum of 2 stages to a maximum of 4 stages).
