Table 2 lists specifications for the Eagle’s standard sensors. Your Eagle
model may not include all of the sensors listed below. The alarm
settings are user-adjustable (see “Updating the Alarm Point Settings”
on page 33.)

4 The PPM range represents the same range as 0 to 100% LEL for that gas. For example, 100% LEL for methane
= 5% by volume = 50,000 PPM. Therefore, the PPM range for methane is 0 to 50,000.
