Hazard
The product presents a serious risk of injuries because, if an emergency were to occur, there is a risk the system may produce a sound that is too quiet. The INC has a preset alarm volume, however in some firmware versions, there is a defect that can cause an individual volume setting to apply to the entire system. If the alarm is not heard or heard too late by people in the building, they may be delayed in getting to safety and may be at risk of receiving injuries.
The product does not meet the requirements of Regulation (EC) 305/2011.
Corrective action
The product has been withdrawn from the market. Affected customers have been informed of the safety risk and actions to take, including a firmware update.
