1. Overview
Y905-G is a 4G remote audible-visual alarm that starts and stops its local alarm in response to network commands. It combines 4G connectivity and local audible-visual indication in one terminal. Y905 is available only as the Y905-G 4G model; there are no Wi-Fi or RJ45 Ethernet versions.
After the device connects to its network, a platform, server, host application, or configured remote-control path can send an alarm-on or alarm-off command. Y905 then starts or stops the local audible-visual alarm. Typical uses include remote equipment-fault indication, pump-room and equipment-room alarms, and warning at unattended sites.
Y905 differs from Y901 and Y902. It receives remote network commands; it does not use their local multi-node push-button trigger architecture.
Operating Principle
- The device connects through
4Gand maintains communication with the configured server or platform. - A remote platform, host system, or control application sends an alarm-on command.
- Y905 activates the local audible-visual alarm.
- A subsequent alarm-off command stops the local alarm.
- Platform logic can issue commands from a schedule, condition, or manual operator action when that logic is included in the project.
Typical Applications
- Remote alarm indication in unattended equipment rooms, pump rooms, and distribution rooms
- Warning at construction sites, warehouses, and temporary stations
- Remote linkage from equipment faults, limit violations, or abnormal operating conditions
- Alarm endpoints controlled by a cloud platform, edge gateway, or network command

6. Installation and Use
Installation
- Install the unit where personnel can see and hear the alarm.
- Keep the 4G antenna away from metal shielding and strong interference.
- Size the power supply for simultaneous network communication and alarm operation.
- If mounted inside another cabinet or enclosure, provide adequate signal clearance and thermal space.
- Verify network registration, communication accessories, and upstream connectivity after installation.
Commissioning
- Configure the network and upstream platform or server before use.
- Test the complete remote alarm-on and alarm-off sequence before service.
- If the project uses platform linkage rules, test reconnection and command behavior after a network interruption.
- Use Y905 for remote alarming and notification. Do not use it as a hard real-time safety interlock.
7. Important Notes
- Control purpose: Y905 receives remote commands to start and stop a local audible-visual alarm.
- Network dependency: Remote control requires the device, network, upstream service, and command path to be available.
- Communication version:
Y905-Guses 4G. Y905 has no Wi-Fi or RJ45 Ethernet version. - Architecture boundary: Y905 is a network-command alarm, not a Y901/Y902 local push-button linkage node.
- Protocol boundary: Confirm the required server, protocol, command format, security, and joint testing before ordering or integration.
- Safety boundary: Y905 supports auxiliary alarming and personnel notification. It must not serve as the only emergency-stop, life-safety, or hard real-time safety circuit.
- Delivered configuration: Confirm the enclosure, mounting, ingress protection, and structural details from the shipped product documents.
