What causes fault code ASRS-FIRE1 (AS/RS Fire Detection / Suppression Activation)?

Actual fire — stored product or packaging ignited. Heat detector or smoke detector false alarm — dust, steam, or temperature spike. Sprinkler head accidentally activated — mechanical impact or corrosion. Fire detection system sensor fault — detector end-of-life or contamination. Fire alarm pull station accidentally activated near the AS/RS area

How do I fix fault code ASRS-FIRE1?

FIRST: Confirm if there is an actual fire — do NOT assume it is a false alarm. If fire confirmed, follow facility emergency action plan — evacuate, call fire department. If confirmed false alarm, identify which detector zone activated — check fire alarm panel annunciator. Check the triggered detector — replace if contaminated, end-of-life, or physically damaged. If sprinkler head activated, water damage to stored product is likely — begin assessment immediately. Fire system reset must be performed by qualified fire alarm technician. Crane restart requires fire system all-clear AND manual verification of AS/RS structure integrity

AS/RS Fire Detection / Suppression Activation

ASRS-FIRE1

Fire detection system in the AS/RS rack structure has activated. Crane operations are halted. Fire suppression may have been deployed.

Probable Causes (ranked)

Actual fire — stored product or packaging ignited
Heat detector or smoke detector false alarm — dust, steam, or temperature spike
Sprinkler head accidentally activated — mechanical impact or corrosion
Fire detection system sensor fault — detector end-of-life or contamination
Fire alarm pull station accidentally activated near the AS/RS area

Fix Steps

1 FIRST: Confirm if there is an actual fire — do NOT assume it is a false alarm
2 If fire confirmed, follow facility emergency action plan — evacuate, call fire department
3 If confirmed false alarm, identify which detector zone activated — check fire alarm panel annunciator
4 Check the triggered detector — replace if contaminated, end-of-life, or physically damaged
5 If sprinkler head activated, water damage to stored product is likely — begin assessment immediately
6 Fire system reset must be performed by qualified fire alarm technician
7 Crane restart requires fire system all-clear AND manual verification of AS/RS structure integrity

Field Trick

After a sprinkler activation in an AS/RS, check the rack structure for water damage to cardboard loads BEFORE running the crane. Water-soaked pallets of cardboard weigh 3x their normal weight and can exceed rack capacity. A collapsed rack section from overweight wet pallets is a catastrophic secondary event.
