4.2.1 Alarm Conditions
CP-10
There are three alarm set points available. These alarm points are normally set at established safety levels, such as the OSHA
Permissible Exposure Limit (PEL) for toxic gases or recognized standards below the Lower Explosive Limit for combustible
gases.
These alarm set points can be changed within limits; see the maintenance section of this manual for the procedure.
When the Oxygen, Toxic or combustible gas concentration reaches the alarm set point, the associated red LED is lit, the
associated relay changes state, and the audio alarm is activated.
Pressing the
S
ELECT
button can temporally disable the Audio Alarm. The horn will be disabled for about five minutes. If a
second alarm condition occurs during this time the horn will re-activate. If the alarm condition(s) have ended during this time
the horn will not re-activate.
