VENTILATION CONTROL
Should a high gas concentration occur (above user-adjustable alarm level), an alarm signal from any
sensor unit starts a 30 second delay. Should the concentration persist through the delay period, the
“alarm” clock is activated. The “on” time of this clock, is user-adjustable in discrete settings from 5 to 55
minutes. Upon activation of the “alarm” clock, the “fan-on” relay energizes and remains energized until
the “alarm” clock” times out. Should the high concentration still be above the alarm level, the “fan-on”
relay will remain ON and the “alarm” relay will energize. This condition is maintained until the high
concentration drops.
