💡 Key Summary: Self-Alarming Wireless Leak Transmitter that Triggers On-Site Alarm and Sends Signals to a Receiver
YH-RF410L TX is a self-alarming wireless transmitter that, when a leak detector (sensor) alarm occurs, wirelessly transmits the signal to a receiver/alarm system while simultaneously activating a signal tower light and buzzer on the transmitter unit itself. It supports 1–10 channel expansion and a sensitivity adjustment function to match site conditions. With an optional backup power (battery), the alarm function can remain active during power outages and other emergency situations.
● Dual Alarm (On-Site + Wireless Transmission): Sends wireless signals to a receiver while also activating the signal tower and buzzer locally for faster response.
● Easy Wireless Installation: Ideal for areas where signal wiring is difficult. Supports easier installation, relocation, and expansion.
● Sensitivity Adjustment Support: Adjustable sensitivity helps stable operation and reduces false alarms in varying site conditions.
● Multi-Channel Expansion: Configurable from 1 to 10 channels to match site scale and number of zones.
● System Consistency: Matches the design tone of Yoohantech standard leak alarm receivers (YH-100L series) for a unified system look.
