Y811-52V — Visual Signaling Alarm Specification
Product series: Industrial Audible & Visual Alarm
This specification covers one YenGear model and two configurations.
1. Product definition
Y811-52V is a compact, visual-only signaling beacon. It provides colored light indication and does not provide an audio output. The two configurations use the same 52-class product form and are selected by the supported color set.
2. Ordering configurations
| YenGear model | Configuration | Light colors | Control |
|---|---|---|---|
| Y811-52V | Three-color | Red, green, yellow in the catalog configuration | Three switch inputs and Modbus RTU over RS485 |
| Y811-52V | Seven-color | Red, green, yellow, blue, white, cyan, and purple | Modbus control |
3. Key features
- Visual-only alarm indication with selectable light color and light pattern
- Modbus RTU control over RS485 for the documented configuration
- Three-color and seven-color ordering options
- ABS enclosure
- Through-hole or bracket mounting
- Low-power DC operation

5. Interfaces and control
The supplied manual documents Modbus RTU with a default address of 01, a default baud rate of 9600, 8 data bits, 1 stop bit, and CRC16 checking. The same manual identifies the yellow conductor as A+ and the green conductor as B-. Verify the wire labels on the delivered unit before energizing it.
The supplied manual documents light control through function code 06 and the light-control register at 00C2. The output mode and color are encoded in the command value. The Y811 technical manual summarizes the verified command family; use the delivered configuration and protocol revision as the final authority.
6. Installation notes
- Switch off power before wiring or changing the mounting.
- Use a regulated DC 12-24 V supply and observe polarity.
- Mount the beacon through the panel opening or with the supplied bracket.
- For RS485, keep the cable away from high-current and high-frequency noise sources.
- Assign a unique device address before connecting multiple devices to one bus.
- Confirm the final ingress-protection marking after the ordered configuration is received.
7. Confirmation items
- Confirm whether the delivered three-color configuration matches the catalog variant or the seven-color variant described in the supplied manual.
- Confirm the final IP rating because the supplied catalog and manual differ.
- Confirm the available input terminals and the seven-color command values for the seven-color configuration.
- Confirm the final connector and wire-color definition from the production drawing.
