The TWR0101R from Zhejiang Jiaboer Electronic Technology Co., Ltd. (JBE brand) is a compact 433 MHz RF wireless alarm remote controller for smart home safety systems. Measuring just 60 mm in diameter and 15 mm thick in a white ABS housing, it interlinks up to 40 wireless detectors — including smoke detectors, heat detectors, and carbon monoxide sensors — into a coordinated alarm network with CE, RoHS, and REACH certifications.

How does wireless interlinking work?

Operating at 433 MHz (with optional 868 MHz ±50 KHz), the TWR0101R transmits alarm and control signals at 10 dBm with under 25 mA transmit current. In standby, consumption drops below 10 μA, enabling up to 10 years of operation from a single CR2450 3V lithium coin cell. When any interlinked detector triggers, the TWR0101R receives and relays the alarm signal across the network, activating all connected alarm devices simultaneously.
