Dsc LC-203 Dual-tech Hardwired Motion Detector

Product Description

The DSC LC-203 is a hardwired dual-technology passive infrared motion detector designed for security system installations. Dual-tech detection combines two sensing technologies to reduce false alarms — both must trigger simultaneously before an alarm event is registered. This design makes the LC-203 well suited for environments where single-technology PIR detectors produce nuisance trips. Licensed security technicians and alarm installers are the primary trades who specify and install this device.

The LC-203 is applicable to residential and light commercial hardwired security panel installations. It is used in spaces where environmental conditions — such as HVAC airflow, temperature fluctuation, or pet activity — can challenge standard single-technology PIR detectors. Typical deployment includes living areas, retail spaces, storage rooms, and other interior zones requiring reliable motion coverage without frequent false activations.

Key Features

• Dual-technology detection requires simultaneous trigger from both sensing elements before alarm activation
• Hardwired connection provides reliable, battery-free signal transmission to the security panel
• Designed for interior zones where false alarm reduction is a priority
• Single-unit package suitable for individual zone wiring

Compatibility

Designed as an OEM-style hardwired motion detector compatible with standard hardwired security panel zone inputs requiring a dual-technology PIR sensor.

Installation Notes

Installation should be performed by a licensed alarm or low-voltage security technician in accordance with local codes and the panel manufacturer wiring guidelines. Power down the security panel and disconnect auxiliary power before wiring the detector. Mount the unit at the manufacturer-recommended height and angle for optimal coverage, and avoid positioning the sensor directly in line with HVAC vents or heat sources that could affect detection performance.
