💡 Key Summary: Stack light–type receiver that centrally manages multi-zone (1–10 channels) leak alarms in one unit
YH-100L is a leak alarm control receiver that receives leak/leakage sensor signals from the field for up to 10 channels and displays each zone status clearly using an LED stack light. When an alarm occurs, a buzzer (70 dB or higher) and indicator lights help operators quickly identify the incident location. Sensitivity and operating modes can be configured to match on-site operating conditions, supporting efficient safety management for industrial equipment and facilities.
● Multi-channel centralized monitoring: Manage signals from 1–10 channels (zones) on one panel for instant visibility of site leak status.
● Flexible sensitivity adjustment: Adjust sensitivity to suit the target medium (water leakage, chemical solutions, etc.) for reliable operation under real site conditions.
● Selectable operating modes: Configure alarm and recovery (reset) behavior to match the facility operation method, improving maintenance efficiency.
● Intuitive status indication: Clearly indicates power/normal/alarm status with color lamps, and supports on-site response with an audible buzzer during alarms.
