The DS-PDSKM-VG3 is a wired seismic detector (shock sensor) designed for indoor alarm applications. It uses a high‑quality G‑sensor to detect impacts and offers adjustable sensitivity and installer-friendly configuration to suit different mounting locations and risk profiles.
Key features
- Detection method: shock sensor (G‑sensor) with detection range up to 5m radius.
- Adjustable sensitivity: 8 levels selectable by DIP switch; includes gross attack override.
- Digital processing: advanced background‑noise filter with indication to help reduce false alarms.
- Alarm output: normally closed (wired).
- LED indicators: blue for alarm; red for noise indication.
- Tamper protection: front and rear tamper supported.
- Additional detection: supports rapid temperature rise detection and displacement detection.
- Robust construction: die‑cast metal housing with IK10 impact resistance.
Electrical and environmental
- Power supply: 9 to 16 VDC (typical 12 V).
- Power consumption at 12 V: maximum current 17 mA; quiescent current 17 mA.
- Operating temperature: -40 °C to 70 °C. Storage: -50 °C to 70 °C.
- Operating humidity: 10% to 90%.
- Dimensions (W×H×D): 60 × 80 × 19.5 mm. Weight: 226 g.
- Application scenario: indoor.
Installer guidance
- Adjust sensitivity with the onboard DIP switch to match mounting surface, expected shock levels and desired detection radius.
- Use the red noise indicator and digital background‑noise filter to help identify and mitigate environmental causes of false alarms during commissioning.
- Requires a wired connection and a 9–16 VDC supply. The device provides a normally closed alarm output for integration with alarm panels that accept NC sensor inputs.
- Tamper protection is provided for both front and rear to detect enclosure opening or removal.
- Recommended for indoor use and for mounting on surfaces where seismic/shock transmission is appropriate.
Note: product performance is based on testing in a controlled environment; results may vary due to external and environmental factors. For best results, update the device firmware to the latest version as recommended by the manufacturer.
Frequently asked questions
- What power supply does the detector need?
- The DS-PDSKM-VG3 requires 9–16 VDC (typical 12 V). At 12 V the maximum and quiescent current are specified as 17 mA.
- How is sensitivity adjusted?
- Sensitivity is set using an onboard DIP switch with eight selectable levels. The unit also includes a gross attack override setting.
- How does the detector connect to an alarm panel?
- The detector provides a normally closed alarm output (wired). It can be connected to alarm panels that accept NC sensor inputs.
- Can this unit be used outdoors?
- The product specification lists the application scenario as indoor. The environmental ratings cover a wide temperature range, but the unit is intended for indoor installation.
- What indicates an alarm or noise condition?
- LED indicators: blue for alarm and red for noise indication. The detector also uses digital background‑noise filtering to reduce false alarms.
- Is the unit vandal resistant?
- Yes. The detector has a die‑cast metal housing with IK10 impact resistance and front/rear tamper protection.
