Y811-95AV — Seven-Color Sounder-Beacon Technical Manual
This manual covers the Y811-95AV seven-color sounder-beacon. Use the Y811-95AV specification as the authority for the ordered supply, protection rating, dimensions, mounting, and interface configuration.
1. Safety and scope
Y811-95AV provides auxiliary audible and visual warning. It is not an emergency-stop circuit, a certified fire-alarm panel, a life-safety system, or a safety-rated control circuit.
The catalog lists DC 12-24 V or AC 220 V. Confirm the delivered voltage marking before wiring. Only qualified personnel may install an AC 220 V configuration. Disconnect all power before opening the enclosure or changing wires.
2. Confirmed configuration
| Parameter | Supplied catalog value |
|---|---|
| Product function | Seven-color audible-visual alarm |
| Trigger inputs | Three switch inputs |
| Communication interfaces | RS485 and RS232 listed |
| Output power | 10 W |
| Memory | 8 MB |
| Supply | DC 12-24 V or AC 220 V |
| Enclosure | ABS |
| Mounting | Screw mounting |
| Dimensions | 94 x 76 mm |
| Ingress protection | IP65 |
The catalog does not provide the RS485 protocol map, default serial parameters, RS232 electrical level, connector pinout, or seven-color command table.
3. Installation and wiring
- Confirm the supply voltage and interface configuration on the delivered unit.
- Confirm the three-input wiring and active level from the production drawing.
- Use screw mounting appropriate for the enclosure and site vibration.
- For RS485, use a twisted pair, keep the bus away from switching noise, and use a daisy-chain topology for multiple devices.
- Do not connect an RS232 port to an RS485 bus.
- Disconnect power before changing any connection.
The supplied catalog does not define RS485 A/B polarity, RS232 level, connector, or wire colors. Follow the delivered cable label and production drawing. Do not infer these details from Y811-52V, Y811-52AV, or Y811-75AV.
4. Communication status
| Interface | Status |
|---|---|
| RS485 | Listed in the catalog; protocol and default serial parameters require confirmation |
| RS232 | Listed in the catalog; electrical level and pinout require confirmation |
| Modbus RTU | Not confirmed for this model |
| Seven-color command map | Not supplied |
Do not apply the Modbus register map, default address, baud rate, CRC settings, or light-command values from another Y811 model. Request the exact protocol sheet for the ordered Y811-95AV configuration before software integration.
5. Commissioning and troubleshooting
Use one device and a short test cable during initial commissioning. Record the delivered interface, serial parameters, address, protocol revision, and connector definition in the service record.
| Symptom | Likely cause | Action |
|---|---|---|
| No light or sound | Wrong supply, disabled output, or wiring error | Check voltage, polarity, terminal labels, and local control wiring |
| RS485 device does not reply | Unknown parameters, A/B reversal, or wrong connector | Stop testing and obtain the model-specific protocol sheet and pinout |
| RS232 integration fails | Wrong electrical level or pinout | Stop wiring and obtain the production drawing |
| One input behaves incorrectly | Wrong common terminal or active level | Confirm the three-input wiring and trigger logic |
| Light command is ignored | Command map from another model was used | Use only the Y811-95AV command reference |
Inspect terminals, cable routing, mounting hardware, the light window, and sound openings during scheduled maintenance.
