In March 2023, we installed a utility tunnel fire monitoring system for Company L. DTS equipment and fiber optic sensing cable measure temperatures at one-meter intervals, with monitoring through an R-type fire alarm receiver and dedicated clients.

The disaster prevention room and utility operations room provide two monitoring locations. The R-type receiver is linked to the fire service for automatic notification when fire is detected.

The system detects fires through DTS and optical sensing cables, transmits zone alarms to the fire alarm receiver and displays their locations, and provides one-meter temperature data on a dedicated monitor. It continuously shows current tunnel temperatures as well as fire conditions.

Functions include two alarm levels for caution and fire, temperature rise trend alarms, Patrol views, automatic hourly/daily/monthly statistics, and reports exportable to Excel.

Topics: fiber optic fire monitoring, certified fire monitoring equipment, utility tunnels, R-type receiver integration, CCTV and panoramic camera integration, and 2D/3D Patrol functions.
