Description
Create an impenetrable perimeter barrier with the Paradox NV780 Series Outdoor Dual Side-View Digital Motion Detector. Specially designed for early-warning boundary protection, this innovative hardwired sensor incorporates two independent, side-by-side passive infrared (PIR) detectors into a single compact housing.
By projecting narrow curtain beams parallel to your exterior walls, the NV780 protects windows, doors, and long corridors before an intruder even attempts entry—all while keeping your property free and clear for daily movement.
Key Performance Highlights
-
- Massive 24-Meter Boundary Protection: Delivers bi-directional coverage up to 24 meters (78 feet) total, reaching up to 12 meters (39 feet) independently on both the left and right sides.
- Dual-Side Active IR Anti-Masking: Features advanced optical monitoring that detects sprayed liquids or blocking items up to 30 cm away within 20 seconds, preventing bypass attempts.
- Full Authority Digital Control (FADEC): Utilizes high-speed digital algorithms and temperature compensation to accurately tell the difference between human movement and environmental noise.
- Cross-Beam Interlocking Array: Each side uses a dual-element sensor configuration that only triggers an alarm when both the upper and lower narrow beams are crossed, effectively neutralizing false trips from falling leaves or ground anomalies.
- Patented 40kg Pet Immunity: Safely ignores pets, stray animals, and large birds weighing up to 40 kg (90 lbs) moving below the lower curtain threshold.
- Configurable Zone Outputs: Can be customized to report as a Single Zone (both sides trigger one unified output) or Dual Zones (each side operates as its own completely independent zone input).

Frequently Asked Questions (Q&A)
Q: How does the dual-side coverage option work?
A: You can select between Single or Dual Zone modes via an internal DIP switch. In Single Mode, a breach on either the left or right side sends an alarm to the exact same zone on your panel. In Dual Mode, the sensor treats the left and right sides as two independent zones, allowing your system to identify exactly which side of the building is being compromised.
Q: Can the beam distance be altered to avoid neighborhood properties?
A: Yes. Each lower beam can be vertically shifted into 5 distinct positions to shorten the range. You can adjust the detection boundary on either side from its maximum 12m down to 10.5m, 7.5m, 5.25m, or 3m.
Q: What happens if someone tries to mask or paint over the lens?
A: The NV780 features active infrared emitter/receiver pairs on both sides. If an intruder covers the lens with cardboard, tape, or sprays it with liquid lacquer, the detector flashes its orange LED indicator and opens its dedicated anti-mask relay to alert your panel instantly.
Q: Can the beams be pushed outward to avoid wall pipes or window shutters?
A: Yes. The internal lens trays can be adjusted horizontally. They can sit at 0° (parallel to the wall) or be moved to a 3° angle. This shifts the outer edge of the beam outward by 60 cm (24 in) to cleanly clear any architectural obstacles.
Installation & Wiring Guide
1. Mount Alignment & Placement Rules
-
- Installation Height: Ensure the NV780 is mounted at 1.5 meters (4.9 feet) or higher from the ground to preserve true pet immunity.
- Levelling: Use the built-in leveling bubble tool integrated directly inside the back plate structure to guarantee a perfect vertical mount.
2. Terminal Block Wiring Configuration
The device functions natively in Relay Mode or Bus Mode (Paradox Combus).
Option A: Traditional Relay Mode Connection
-
- RED (+): Connect to 12VDC Auxiliary Power (+).
- BLK (-): Connect to Auxiliary Ground (-).
- RLY L (NC/COM): Connect to the Left Side Panel Zone Loop (Active in Dual Mode).
- RLY R (NC/COM): Connect to the Right Side Panel Zone Loop (Acts as the main joint loop in Single Mode).
- TMP (NC/COM): Connect to the 24-Hour Panel Tamper Loop.
Option B: Addressable Bus Mode Connection
-
- RED (+) / BLK (-): Connect directly to the Paradox system power combus.
- GRN (RX) / YEL (TX): Connect to the panel’s green and yellow communication lines.
- (Note: The panel automatically overrides settings digitally once it reads the green and yellow data connections).
3. DIP Switch Setup
- Switch 1 (LED): ON enables the diagnostic LEDs (Default); OFF disables them for covert operation.
- Switch 2 (Buzzer): ON enables the internal audible walk-test beeper; OFF mutes it.
- Switch 3 (Sensitivity): ON sets detection to High (100%); OFF drops it to Normal (75%).
- Switch 4 (Zone Mode): ON configures the sensor to Single Zone Output; OFF splits it to Dual Zone Outputs.
