DS-PDSKM-VG3 Wired Seismic Detector (Shock Sensor)

Model / SKU: DS-PDSKM-VG3

DS-PDSKM-VG3 Wired Seismic Detector (Shock Sensor). Wired seismic (shock) detector with high‑quality G‑sensor for early impact detection. Adjustable sensitivity, front/rear tamper protection and IK10 die‑cast metal housing for indoor installations. Detection range: up to 5m radius 8 sensitivity levels via DIP switch; gross attack override Wired output (Normally Closed), 9–16 VDC supply 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.
