Overview
Y901 is a wireless alarm terminal for distributed sites. Pressing the built-in latching button activates the local alarm and the alarms on linked nodes. No external DI or platform remote-trigger command is provided. All triggered buttons must be reset before the network-wide alarm clears.
Typical applications
- Tunnels, utility corridors, underpasses, and inspection routes.
- Pump stations, equipment rooms, factories, and outdoor alarm points.
- Sites where alarm wiring is difficult or too expensive.
Key Features
- Any-node trigger with network-wide alarm linkage.
- Built-in latching button: press to latch the alarm; press again to reset.
- Y901-L uses LoRa automatic relay networking: standard open-area range up to 5 km, with an optional 10 km version. Y901-G uses a 4G platform or server to synchronize alarms, not LoRa relay networking.
- 95 dB buzzer and flashing red LED.
- 9 to 36 VDC power input and IP67 enclosure.
How it works & selection
Safety Boundary
For auxiliary alarming and personnel notification only. Do not use it as the sole emergency-stop or life-safety circuit.
Selection notes
Send the site distance, node quantity, communication version, and required communication architecture. Wireless distance depends on terrain, antenna installation, and obstruction level.
