TOXALERT’S Model TOX-REFRIG Refrigerant Leak
Monitoring System consists of a remote refrigerant sensor
or sensors and a controller/annunciator panel. The TOX-
REFRIG system is designed to continuously monitor
mechanical refrigeration equipment rooms for refrigerant
leaks and upon detecting a leak, the unit shall start
ventilation equipment and annunciate alarm conditions.
ANSI/ASHRAE Standard 15-2010 calls for the use of
refrigerant leak detectors.

The controller’s first stage or “Warning (Purge) Stage”
activates a set of relay contacts to operate exhaust fan(s) or
other mechanical equipment, and the sensor LED on panel
front will light green. The second stage or “Alarm Stage”
activates an audible alarm with reset and silence
pushbutton switch, an auxiliary set of relay contacts, and
the sensor LED on panel front will light red. On a
decrease in refrigerant concentration, the alarm stage
automatically resets and the warning stage is field
selectable for manual or automatic reset- (manual reset
select). If the manual reset select option is turned on and
the sensor detects a warning or alarm condition, the
warning relay will remain activated and the sensor LED on
panel front will blink green, even after the concentration
has decreased. That function can be manually reset via a
reset button located on panel front.

A “Purge” switch on the controller front has two positions-
ON & AUTO. In the AUTO position, the warning stage
relay energizes automatically from sensor monitoring; in
the ON position, the warning contacts are manually
energized.
