alarms from birds and flying
insects.
- nuisance alarm can also
result from an insect
crawling on the lens
- Sunlight passing through
windows can heat interior
surfaces

Sensors
32. Passive Infrared Sensors (thermopile or pyroelectric)
o Cautions
- should be installed
away from heat
sources
- should not be
mounted over or near
radiators, heaters, hot
pipes, or other
heating elements

34. Proximity Sensors (capacitance)
o Characteristics
- radiates energy and
detects change in the
capacitive coupling
between an antenna
and the ground
