Passive Infrared Single or Dual Circuit Wall Switches
The H-MOSS® Passive Infrared single and dual
circuit wall switch, represent the state-of-the-art
in sensor technology utilizing passive infrared
(PIR) 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 AP1277 Series also feature
selectable operating modes - automatic ON/OFF or
manual ON/automatic OFF, and a built-in photocell
for automatic daylight harvesting.

maintenance free “Install and Forget” operation.
Automatic false-on, false-off correction.
All-Digital, Passive Infrared sensor Excellent 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)
— AP1277x2 and AP1277x2N.
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 sufcient natural light.
Manual SuperSaver mode – in addition to above, turns lights off during
periods of occupancy if ambient light levels increase sufciently to illuminate
the area.
Tamper-proof automatic only
version available
Automatically turns lighting loads on and off. Manual override button is not
provided — AP1277x1N and AP1277x2N.
