2. Important Safety Information
Read all instructions carefully before installation and operation. Failure to follow these instructions may result in property damage, injury, or death.
- Disconnect all power to the circuit before installing or servicing the device.
- Installation should be performed by a qualified technician in accordance with all local and national electrical codes.
- Do not expose the device to extreme temperatures or direct sunlight for prolonged periods.
- Ensure the device is installed in a location where it can effectively detect moisture without being accidentally triggered.
3. Installation Guide
Follow these steps for proper installation of your Wet Switch Flood Detector:
- Power Disconnection: Ensure the main power supply to the area where the detector will be installed is turned off at the circuit breaker.
- Mounting Location: Select a flat, stable surface at the lowest point where water is likely to accumulate. Ensure the sensor pads on the bottom of the device can make direct contact with any pooling water.
- Wiring:
- Connect the 24 VAC power supply wires to the detector. The red wire typically connects to the positive (+) 24 VAC terminal, and the black wire connects to the common (-) 24 VAC terminal. Refer to the device label for specific wiring details: "24 VAC RED BLACK".
- Connect the output signal wires (Orange, White, Green) to your control system or alarm panel as required. The specific function of each wire (e.g., normally open, normally closed) will depend on your system and the detector's internal relay configuration. Consult your control system's manual for proper integration.
- Secure Mounting: Secure the detector firmly in place using appropriate fasteners (not included).
- Power Restoration: Once all connections are secure and verified, restore power to the circuit.
4. Operation
The DiversiTech WS-1 Wet Switch operates automatically once installed and powered.
4.1 Indicators
- POWER ON: A green indicator light illuminates when the device is receiving 24 VAC power.
- MOISTURE: An orange or red indicator light illuminates when moisture is detected by the sensor pads. This also triggers the internal relay, sending a signal to the connected control system.
4.2 Testing the Device
To ensure proper functionality, periodically test the detector:
- Press and hold the green "PUSH TO TEST" button.
- The "MOISTURE" indicator light should illuminate, and the connected alarm or control system should activate, simulating a flood detection event.
- Release the button. The "MOISTURE" light should turn off, and the alarm should deactivate.
4.3 Resetting the Device
After a moisture detection event or a test, the device may need to be reset:
- Ensure the area around the sensor pads is completely dry.
- Press and hold the red "PUSH TO RESET" button until the "MOISTURE" indicator light turns off.
- Release the button. The device is now reset and ready for further detection.
5. Maintenance
The DiversiTech WS-1 Wet Switch requires minimal maintenance to ensure reliable operation.
- Regular Cleaning: Periodically inspect the sensor pads for dust, debris, or corrosion. Gently clean with a soft, dry cloth if necessary. Do not use abrasive cleaners or solvents.
- Periodic Testing: Test the device monthly using the "PUSH TO TEST" button to confirm it is functioning correctly.
- Environmental Check: Ensure the installation area remains free from obstructions that could prevent water from reaching the sensor pads.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No Power Indicator | No 24 VAC power | Check power supply and wiring connections. Ensure circuit breaker is on. |
| Moisture Indicator On, No Water | Sensor pads are wet or dirty; device needs reset | Dry sensor pads thoroughly. Press "PUSH TO RESET" button. Clean sensor pads if dirty. |
| Device Not Triggering with Water | Sensor pads not making contact; faulty wiring; device malfunction | Ensure water reaches sensor pads. Check wiring connections. Test device with "PUSH TO TEST" button. If issue persists, contact support. |
| Test Button Not Working | No power; faulty button | Check power indicator. If power is on and test fails, contact support. |
