H-MOSS® Occupancy Sensors
Key Features
• All-Digital, Dual Technology Sensor
• Adaptive Technology – No Manual Adjustment Required
• Built-In Photocell with SuperSaver Mode
• Two Relays for Two Level Switching or Dual Load
Control (AD1277x2 and AD1277x2N)
• Zero Arc Point Switching
Dual Technology Single or Dual Circuit Wall Switches
The H-MOSS® Dual Technology single and dual
circuit wall switch, represent the state-of-the-art
in sensor technology utilizing both ultrasonic and
passive infrared motion sensing technology. They
also have Adaptive Technology that continuously
analyzes its environment and auto adjusts the
sensitivity and timer based on environmental history,
eliminating the need for manual adjustment. This
helps provide true maintenance free “Install and
Forget” operation. The AD1277 Series also feature
selectable operating modes - automatic ON/OFF or
manual ON/automatic OFF, and a built-in photocell
for automatic daylight harvesting.

Features and Benets
Features Benets
Adaptive Technology Sensor automatically determines optimum setting. Self-adjusting timer and
passive infrared sensitivity.
No manual sensitivity and timer adjustments required – providing
maintenance free “Install and Forget” operation.
Automatic false-on, false-off correction.
All-Digital, Dual Technology sensor Combines excellent ultrasonic minor motion detection with outstanding
passive infrared long-range motion detection.
Auto ON or Manual ON operating modes Provides Auto ON / Auto OFF or Manual ON / Automatic OFF operation.
Two relays for two level switching or dual
load control
Controls two circuits independently (120V AC or 277V AC) —
AD1277x2 and AD1277x2N.
No minimum load requirement Allows for connection of loads from 0 to full load capacity.
Hard lens Impact resistant IR lens.
Built-in photocell with manual SuperSaver
mode for daylight harvesting.
Increases energy savings by preventing the lights from turning on when there
is sufcient natural light
Manual SuperSaver mode – in addition to above, turns lights off during
periods of occupancy if ambient light levels increase sufciently to illuminate
the area.
Tamper-proof automatic only
version available
Automatically turns lighting loads on and off. Manual override button is not
provided — AD1277x1N and AD1277x2N.
