5. Setup and Installation
Follow these steps to install your WSDCAM Freezer Door Alarm:
- Insert Batteries: Open the battery compartment on the back of the alarm unit and insert two AAA alkaline batteries (not included), ensuring correct polarity.
- Choose Installation Location: Select a clean, dry, and flat surface on your door/window frame and the corresponding door/window. Ensure the surfaces are free of dust and grease.
- Prepare for Adhesion: The alarm unit and magnetic strip come with pre-applied double-sided adhesive tape. Peel off the protective backing from both the alarm unit and the magnetic strip.
- Mount the Alarm Unit: Attach the main alarm unit to the door/window frame.
- Mount the Magnetic Strip: Attach the magnetic strip to the door or window itself, aligning it with the alarm unit. Ensure the alignment arrows on both parts point towards each other. The installation distance between the alarm unit and the magnetic strip should not exceed 0.78 inches (2 cm) when the door/window is closed.
- Test Installation: Close and open the door/window to verify that the alarm detects the change in state.
6. Operating Modes
The WSDCAM Door Alarm offers four distinct operating modes, selectable via the buttons on the unit. The video below demonstrates these modes.
6.1. Power On/Off
- To Power On: Press and hold the On/Off button until the LED indicator lights up.
- To Power Off: Press and hold the On/Off button until the LED indicator turns off.
6.2. Mode Selection
Press the corresponding button on the alarm unit to switch between modes:
- Normal Alarm Mode: The alarm sounds when the door/window opens and stops when it closes. Ideal for general security where immediate alert and self-resetting are desired.
- Constant Alarm Mode: The alarm sounds continuously once the door/window opens, even if it is closed again. This mode is suitable for situations requiring a persistent alert until manually disarmed.
- Time Delay Alarm Mode: Designed for refrigerators and freezers. The alarm will only sound if the door remains open for a pre-set delay time (3, 15, 30, or 60 seconds). This prevents false alarms during normal use. The sound starts from 0dB and gradually increases to 108dB.
- Doorbell Mode: The unit will sound a 'DingDong' chime once when the door/window opens. Perfect for notifying you of arrivals or departures without a loud alarm.
6.3. Setting Time Delay (for Time Delay Alarm Mode)
To adjust the delay time in Time Delay Alarm Mode, refer to the specific button on the alarm unit (as shown in Figure 5.2). Repeatedly press the Time Delay Mode button to cycle through the available delay options (3, 15, 30, 60 seconds). The LED indicator may provide feedback on the selected delay.
7. Maintenance
7.1. Battery Replacement
The alarm unit is powered by two AAA alkaline batteries. When the batteries are low, the LED indicator will flash once every second. To replace the batteries:
- Carefully remove the alarm unit from its mounted position (if necessary).
- Open the battery compartment cover on the back of the unit.
- Remove the old batteries and insert two new AAA alkaline batteries, ensuring correct polarity (+/-).
- Close the battery compartment cover securely.
- Re-mount the alarm unit if it was removed.
7.2. Cleaning
To clean the alarm unit and magnetic strip, use a soft, dry cloth. Do not use abrasive cleaners, solvents, or immerse the device in water, as this may damage the electronics.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Alarm does not sound when door/window opens. | 1. Batteries are dead or incorrectly inserted. 2. Magnetic strip is too far from the alarm unit. 3. Alarm is powered off or in an incorrect mode. | 1. Replace batteries and check polarity. 2. Realign the magnetic strip and alarm unit; ensure gap is less than 0.78 inches. 3. Power on the alarm and select the desired mode. |

9. User Tips
- For optimal performance, ensure the alarm unit and magnetic strip are installed on a flat, clean surface.
- When installing on a refrigerator or freezer, consider placing the alarm unit on the door and the magnetic strip on the frame, or vice-versa, ensuring the alignment arrows face each other and the gap is minimal when closed.
- Regularly check the LED indicator for low battery warnings to ensure continuous protection.
- Experiment with the different delay times in Time Delay Alarm mode to find the setting that best suits your needs for appliances.
