H280, H280NC
OPERATION
The H280 and H280NC load status switches monitor both voltage and current on
manually switched loads (e.g., lights/fans in bathrooms). This device provides status
monitoring for loads that are not, or cannot be, controlled by a building control
system. The H280 has a normally open (N.O.) output switch, while the H280NC is
normally closed (N.C.). Dual colored LEDs provide easy indication of output, with
green for normal output and red for alarm status. The H280 and H280NC require no
external power to generate the output.

NOTE: Incidental loads as small as 30 mA AC connected in parallel to the sensed load (e.g. pilot
lamps or control circuits) might draw enough current to give a false load presence signal, even
though the true load has been interrupted.
