Generating stop flow
The detector has a dedicated switch output, called “stop flow” that becomes
active when a heater, gas flow, or lamp failure occurs.
To use the stop flow function, make the connections shown in the following
table and figure.
Warning:
Fire and explosion hazard. Failure to connect the stop flow
output could cause the detector to flood.
