3.5 The Alarms Menu
Cannonball3 gas alarms are user-adjustable and may be set
anywhere within the range of the sensor channel. When an
alarm set point is exceeded for a sensor, a loud audible alarm
sounds, and the three bright red LED alarm lights blink.
Cannonball3 alarms are self-resetting unless the alarm latch is
enabled. With the alarm latch disabled, visible and audible
alarms cease when readings drop back below the pre-set
alarm levels. With the alarm latch enabled, visible and audible
alarms continue to sound after the atmospheric hazard has
cleared. The user must then manually reset them by pressing
the MODE button.
Alarm latch procedures are discussed in section 3.5.3.
Factory default settings can be restored at any time during
normal operation by using the procedures discussed in
section 3.5.4.
