1. Overview
The Y901 is a multi-point wireless mesh alarm that integrates a latching switch and an audible/visual alarm. With IP67 protection, it enables rapid on-site alerting with "one-touch triggering, local alarm, and network-wide linkage." It is available with 4G or LoRa communication, corresponding to the Y901-G and Y901-L models.
The system supports a multi-node self-organizing wireless network. When the latching switch on any node is triggered, or when an external alarm contact closes, the local audible/visual alarm is activated immediately and the alarm status is synchronized to the other nodes. Once the signal is received, the other nodes also activate their audible/visual alarms. If one node is triggered, all nodes enter the alarm state. The network-wide alarm is cleared only after all trigger sources have been reset.
Trigger Methods
The Y901 supports multiple trigger methods to meet different alerting requirements:
| Method | Description |
|---|---|
| Manual Button (Default) | Built-in latching button maintains the trigger state after being pressed; suitable for on-site emergency assistance or incident reporting |
| Sensor Input | Supports external sensors such as door contacts, float switches, and PIR sensors; alarm is triggered through a dry contact input |
| Remote Command | Supports alarm triggering by remote command from a monitoring center |
| Custom | Additional trigger methods can be customized on request |
Network Topology
The Y901 employs a multi-point wireless architecture with automatic relay networking, extending alarm coverage across multiple nodes without complex wiring.
Operating Principle
- When the latching switch on any node closes, that node enters the alarm state immediately
- The alarm status is synchronized to the other nodes through the wireless network
- After receiving the alarm signal, the other nodes also activate their local audible/visual alarms, so all nodes alarm simultaneously
- The nodes support automatic relay networking, and the system automatically searches for better communication paths to extend coverage
- The network-wide alarm stops only after all trigger conditions have been cleared
Application Scenarios
- Emergency alerting in long-distance areas such as tunnels, underpasses, and utility corridors
- Distributed linkage alarm applications for factory production lines, equipment rooms, and pump stations
- Assistance and warning applications in construction sites, inspection routes, and hazardous areas
- Multi-point wireless interlocked alarm applications where wiring is impractical
- Alerting scenarios in humid, dusty, or outdoor environments where waterproof protection is required

6. Important Notes
- Linkage retention logic — As long as any node remains in the triggered state, the network-wide alarm remains active; one triggered node causes all nodes to alarm
- Communication variants —
-Gindicates4G, and-LindicatesLoRa - Antenna installation — The wireless antenna should be kept away from enclosed metal cabinets to avoid affecting wireless performance
- Field reset — After the latching switch is triggered, it must be reset manually before the system can exit the alarm state
- Networking method — The device supports wireless mesh linkage and can extend multi-node alarm coverage without complex wiring
- Protection capability — The unit is rated
IP67, but prolonged immersion and abnormal pressure should still be avoided during installation - Product parameters — Structural details, mounting method, and configuration details are subject to the actual shipped version
