Description
Before installing, please read the Directional Sound Applications Guide, avail- able through System Sensor. The installation must meet the requirements of the authority having jurisdiction, CAN/ULC S524 and CSA C22.1. Directional sounders are used as supplemental signals on a fire alarm system to aid in the evacuation of building occupants. Although directional sounders may be con- nected to notification appliance circuits (NAC) for fire alarm service, they are not a replacement for audible or visible notification appliances as required by the authority having jurisdiction.
