Model: GS-101
This manual provides comprehensive instructions for the installation, operation, maintenance, and troubleshooting of your Skylink GS-101 Garage Door Sensor. The GS-101 is designed to notify you when a garage door is open, enhancing home security. Please read this manual thoroughly before installation and use to ensure proper function and safety.

Figure 1: Skylink GS-101 Garage Door Sensor Main Unit. The image displays the main unit of the Skylink GS-101 Garage Door Sensor. It is a grey, rectangular device with a cylindrical extension at the bottom, featuring a small wheel. A red indicator light is visible on the front, along with the 'AAA+' logo. The top section shows mounting holes for installation.
The Skylink GS-101 is a sensor designed to detect the position of a garage door. When installed correctly, it communicates with a compatible receiver (sold separately) to alert users to the door's status. It features a plunger mechanism that is activated when the garage door is closed, and deactivated when open.
Carefully remove all components from the packaging. Ensure you have the GS-101 sensor unit and any included mounting hardware.
The GS-101 requires batteries for operation. Locate the battery compartment, typically on the back or side of the unit. Insert the required Lithium batteries, ensuring correct polarity (+/-). The unit includes batteries.
Select a suitable location on your garage door frame or wall. The sensor should be mounted where the plunger mechanism can be depressed when the garage door is closed and released when the door is open. Avoid direct exposure to extreme heat or sunlight, especially on metal garage doors, as this can affect performance and longevity.
The GS-101 operates with a compatible Skylink receiver (e.g., GM-318R or similar models). Refer to your receiver's instruction manual for specific pairing procedures. Generally, this involves putting the receiver into a learning mode and then activating the GS-101 sensor (e.g., by opening/closing the garage door) to transmit its signal.
Once installed and paired, the Skylink GS-101 operates automatically. When the garage door is opened, the sensor's plunger is released, triggering a signal transmission to the paired receiver. When the garage door is closed, the plunger is depressed, indicating a closed state.
The GS-101 uses Lithium batteries. When the battery level is low, the sensor may exhibit a specific indicator (e.g., a rapid flash of the red LED or a notification from the receiver). To replace batteries:
Wipe the sensor unit with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these can damage the plastic housing or electronic components.
| Problem | Possible Cause | Solution |
|---|---|---|
| Sensor not responding or receiver not receiving signals. |

|
| False alarms or inconsistent readings. |
