1. Introduction
The DSC SS102 Seismic Vibration Sensor is designed to detect shock and vibration, providing an essential layer of security for various applications. This manual provides detailed instructions for the proper installation, operation, and maintenance of the SS102 sensor to ensure optimal performance and reliability within your security system.
2. Key Features
- Seismic vibration detection for enhanced security.
- Adjustable pulse count for false alarm prevention.
- Integrated LED indicator for status and testing.
- Suitable for indoor shock/vibration detection.
- Surface mount installation.
3. Safety Information
Please read all instructions carefully before installing or operating the DSC SS102 sensor. Failure to follow these instructions may result in improper operation, damage to the device, or personal injury.
- Installation should be performed by qualified personnel only.
- Disconnect power to the control panel before performing any wiring or maintenance.
- Ensure all wiring connections are secure and correct according to the control panel's specifications.
- Do not expose the sensor to extreme temperatures or moisture beyond its specified operating conditions.
- This device is intended for indoor use only.
4. Installation and Setup
Proper installation is crucial for the optimal performance of the SS102 sensor. Follow these steps carefully:
4.1 Mounting Location
- Select a solid, stable surface that is directly connected to the area you wish to protect (e.g., a wall, window frame, or safe).
- Avoid mounting on surfaces that are prone to excessive vibration from non-security related sources (e.g., heavy machinery, air conditioning units).
- Ensure the mounting surface is clean and dry.
4.2 Physical Installation
- Carefully open the sensor casing to access mounting holes and terminals.
- Using appropriate screws, securely mount the sensor to the chosen surface. Ensure it is firmly attached to transmit vibrations effectively.
- Refer to the diagram below for typical mounting orientation and component identification.

4.3 Wiring
Connect the sensor to your alarm control panel according to the panel's instructions and the SS102 wiring terminals. Typically, this involves connecting to a zone input and power supply.
- Identify the alarm output terminals and power input terminals on the SS102.
- Connect the power supply (e.g., 12V DC) to the designated power terminals.
- Connect the alarm output to a supervised zone input on your control panel.
- Ensure proper polarity for power connections.
4.4 Sensitivity and Pulse Count Adjustment
The SS102 features adjustable sensitivity and pulse count to prevent false alarms while ensuring reliable detection.
- Sensitivity Adjustment: Use a small screwdriver to adjust the sensitivity screw (refer to Figure 1). Turn clockwise to increase sensitivity, counter-clockwise to decrease. Test the sensor after each adjustment.
- Pulse Count: The pulse count setting determines how many consecutive shock events are required within a short period to trigger an alarm. This helps differentiate between genuine threats from minor environmental disturbances. Consult your control panel or sensor documentation for specific pulse count settings if available, or adjust based on thorough testing.
5. Operation
Once installed and configured, the DSC SS102 sensor continuously monitors for seismic vibrations. When the detected vibration level exceeds the set sensitivity threshold for the specified pulse count, the sensor will trigger an alarm condition, signaling the connected control panel.
- LED Indicator: The integrated LED (refer to Figure 1) provides visual feedback during testing and operation. It typically illuminates briefly upon detection of a shock event, and may indicate an alarm condition depending on the system's configuration.
- Testing: Regularly test the sensor by applying controlled impacts to the protected surface (e.g., tapping firmly near the sensor) to ensure it triggers an alarm at the desired sensitivity level.
6. Maintenance
The DSC SS102 sensor requires minimal maintenance to ensure long-term reliability.
- Cleaning: Periodically wipe the sensor's exterior with a soft, dry cloth to remove dust. Do not use abrasive cleaners or solvents, as these may damage the casing or internal components.
- Testing: Perform functional tests at least annually, or more frequently in high-security applications, to verify proper operation and sensitivity settings.
- Environmental Check: Ensure the sensor remains free from moisture, extreme temperatures, and physical damage.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Sensor not triggering | Low sensitivity setting, improper wiring, power issue, faulty sensor. | Increase sensitivity, check wiring connections to the control panel, verify power supply, test sensor functionality. |
| False alarms | High sensitivity setting, low pulse count, environmental vibrations, improper mounting. | Decrease sensitivity, increase pulse count, relocate sensor if necessary, ensure secure mounting to a stable surface. |
| LED not illuminating | No power, faulty LED, sensor not detecting events. | Check power connections, test sensor for detection by applying a shock, contact support if LED remains non-functional. |
