Some DRY-O-TRON

units may be connected to fire/smoke alarms, which may be tested periodically. In this
case, activation of the alarm will cause an immediate shut-down of the unit. Activation of the fire/smoke alarm may
also cause fire dampers (by others) or other devices to close.
After the test, and when safe to do so, restarting the unit requires:
For units with automatic
fire/smoke-alarm reset
1. Reset the fire/smoke alarm system (by others). Be sure that the alarm’s isolated output to the DRY-O-TRON
®

2. Confirm that any fire dampers or fire doors are back to the normal operating position.
3. The unit should re-start automatically.
For units with manual
