4. Operation
The ZFD Model 85A security tag operates by interacting with an AM58Khz EAS system and through its internal cut-lanyard alarm.
- EAS System Interaction: When a secured item passes through an AM58Khz security gate or sensor, the tag will trigger an audible and visual alarm from the sensor system.
- Lanyard Cut Alarm: If the metal lanyard is tampered with or cut, the tag itself will activate an internal sound and light alarm, providing immediate notification of a potential theft attempt.

5. Maintenance
The ZFD Model 85A security tag is designed for durability and reusability. To ensure optimal performance and longevity:
- Cleaning: Wipe the tag with a soft, dry cloth to remove dust or dirt. Avoid using harsh chemicals or abrasive materials.
- Storage: Store tags in a clean, dry environment when not in use.
- Battery: The tag includes 1 CR2 battery. Replace the battery as needed to ensure the lanyard cut alarm function remains active.
6. Troubleshooting
Tag Not Alarming with EAS System
- Frequency Mismatch: The most common reason for a tag not alarming is an incompatibility with the EAS system's frequency. The ZFD Model 85A operates on AM58Khz. Ensure your security sensors are also AM58Khz. If your system operates on a different frequency (e.g., RF8.2Mhz), this tag will not trigger an alarm.
- Sensor Placement: Verify that the security sensors are correctly installed and calibrated according to their manufacturer's instructions.
- Tag Placement: Ensure the tag is properly applied to the merchandise and is not obstructed by other materials that could interfere with the signal.
Lanyard Cut Alarm Not Functioning
- Battery Check: The internal alarm requires a functional battery. Check if the CR2 battery needs replacement.
- Lanyard Connection: Ensure the lanyard is correctly inserted and locked into the tag's mechanism. A loose connection may prevent the alarm from activating.
