INSTALLATION INSTRUCTIONS
1. INTRODUCTION
Your TOXALERT ventilation control system incorpo-
rates the latest in solid state technology to give you
maximum reliability and performance. The system
alarm setpoint can be adjusted to activate fans upon
detection of an unsafe gas concentration such as carbon
monoxide, carbon dioxide, diesel smoke. In addition, a
user definable hourly repeat cycle is provided, allowing
time based, as well as concentration based fan activa-
tion. In both modes of fan control, the “on “ time is
user adjustable from 1 to 8 minutes in one minute
increments. For optimum performance, install, burn-in,
and check out your TOXALERT system exactly as
instructed. If your TOXALERT can’t be calibrated or
fails checkout, please contact your local representative
or TOXALERT International for servicing.
