Detector
General Description
The NV780MX is a dual, independent, side-by-side view Passive
Infrared (PIR) motion detector with dual anti-mask in a single
housing, providing boundary protection. Covering approximately
24m / 78 ft. (12m / 39 ft. on each side) and configurable to report
either as a single unit with two sides reporting as a single zone
output or as a dual unit with each side reporting as a separate
zone input.
Installing the NV780MX
Figure 1 : Front View - Open Cover
Minimum Recommended Installation Distance: At least 40 cm /
15.7 in. from the protected area (door, window, etc.)
Anti-Mask Calibration
The anti-mask will only calibrate after the tamper is closed. The
NV780MX performs anti-mask calibration for up to 40 seconds,
indicated by flashing red / green LEDs until completed. On
completion, the LEDs shut off. If the buzzer is set to ON, three
beeps signal that calibration is complete.
IMPORTANT: During calibration, no objects should be within 2m /
6 ft. of the anti-mask field of view (on both sides of the detector).
Wiring
• Digiplex mode is enabled if bus communication with the control
panel exists. In Digiplex mode, the detector’s relay output
remains active and can be used to activate other devices.
• Upon a loss of communication in Digiplex mode, the left LED
flashes rapidly until communication is restored.
• To return to Relay mode, disconnect both the power and the
Digiplex bus connection, and then power-up the module.

• LED: Both left and right LEDs blink red for five seconds.
• Buzzer Switch ON:
• Single Mode: One tone beeping for five seconds.
• Dual mode: Alternate tone beeping for five seconds.
• Anti-mask calibration can take up to 40 seconds, red / green
flashing if Buzzer is ON; three beeps indicates completion.
Alarm
• LED: Red LED indication on the relevant side(s) for three
seconds.
• Buzzer Switch ON:
• Single Mode: Same tone for either side detection.
• Dual mode: Each side has its own tone.
Anti-Mask Detection
• LED: Flashes orange rapidly (pre-alarm state) and then
flashes when in alarm.
• If Buzzer is ON: buzzer beeps for 3 seconds.
NOTE: The anti-mask relay is open during anti-mask detection.
