4. Setup and Installation
Proper installation is crucial for the effective operation of your Techko S187D Safe Pool Alarm. Follow these steps carefully:
- Choose Installation Location: Decide where to install the alarm (e.g., pool gate, door, window, or other entry point to your pool area).
- Clean the Surface: Ensure the installation surface is clean, dry, and free of any debris for optimal adhesive performance.
- Attach Magnetic Sensors: Remove the adhesive backing from the magnetic sensors and attach them to the entry point. Ensure they are aligned and close enough to trigger the alarm when separated.
- Mount the Alarm Unit: Use the included adhesives or screws from the mounting kit to securely attach the main alarm unit to the surface. Position it out of reach of children (typically 54 inches or higher).
- Install Secondary Bypass Button: Attach the secondary bypass button to the opposite side of the door/gate using adhesives. Plug its cable into the bottom of the main alarm unit.
- Insert Battery: Open the battery compartment (usually at the bottom or back of the unit), connect a 9V battery (not included) to the terminal, and place it inside. Close the compartment securely.
- Test the Alarm: Open and close the gate, door, or window. The alarm should sound when the magnetic contact is broken without pressing the bypass button.

5. Operation
The Techko S187D Safe Pool Alarm operates to provide immediate alerts for unauthorized entry into your pool area.
- Alarm Activation: When the magnetic contact between the main unit and its sensor (or secondary sensor) is broken, the high-output 110-115 dB alarm will sound immediately.
- Bypass Function: To temporarily disable the alarm for 10 seconds (e.g., for authorized entry/exit), press the "BYPASS" button on the main unit or the secondary bypass button before opening the entry point. The LED indicator will blink during the bypass period. After 10 seconds, the alarm will automatically re-arm.
- Screen Door Functionality: If using the patented screen door sensor, you can keep the main sliding glass door open without triggering the alarm, provided the screen door remains closed and its sensor contact is maintained.

6. Maintenance
- Battery Replacement: The alarm requires one 9V battery (not included). A red "Low Battery" LED indicator will remain on when the battery needs to be replaced. Replace the battery promptly to ensure continuous protection.
- Cleaning: Wipe the alarm unit and sensors with a soft, damp cloth as needed. Avoid using harsh chemicals or abrasive cleaners.
- Weather Resistance: The unit has an IP65 waterproof rating, making it resistant to moderate rain and snow. However, avoid submerging the unit in water.

7. Troubleshooting
- Alarm Not Sounding:
- Check if the 9V battery is installed correctly and is not depleted (look for the "Low Battery" LED).
- Ensure the magnetic sensors are properly aligned and separate sufficiently when the entry point is opened.
- Verify that the bypass button is not pressed or stuck.
- False Alarms:
- Ensure the magnetic sensors are securely attached and do not shift, causing accidental separation.
- Check for any obstructions that might be interfering with the sensor alignment.
- Bypass Button Not Working:
- Confirm the secondary bypass button is correctly plugged into the main unit.
- Ensure the button is fully depressed and released.
