Toxalert CM203 - Manual (Page 2)

The Model CM200 series has a two color LED (light-emitting diode) to indicate its operating status.
When the LED is flashing green, operation is normal and unit is not in alarm. When the LED is flashing
red, the unit is sensing CO above its setting. A continuous red or green indicates failure; and LED off
indicates power failure.
Model CM201 is a single stage carbon monoxide monitor with audible alarm. A red LED and audible
alarm activate when the concentration of CO exceeds the factory-set (user-adjustable) level.
Model CM202 is a two stage carbon monoxide monitor with a relay output for each stage. If the CO
concentration rises and stays above the warning stage setpoint (field adjustable) for a delay period of
thirty seconds continuously, the warning relay, amber warning LED, and a three minute minimum on
timer shall activate. The warning stage shall be activated for a minimum of three minutes and then deacti-
vate if the CO concentration is below the warning stage setpoint. Should the CO concentration remain
above the warning stage setpoint for longer than three minutes, the warning stage shall remain activated
until the CO concentration falls below the warning stage setpoint. If the CO concentration should con-
tinue to rise above the alarm stage setpoint (field adjustable) and remain above the alarm setpoint for a
period of ten minutes, then the alarm stage relay and red alarm LED shall activate.
Model CM203 is a two stage carbon monoxide monitor with a warning stage relay and an audible alarm
with silence switch that is activated by the alarm stage. The operation is the same as the Model CM202
except that the audible alarm replaces the alarm relay.
