Siren Connection Module  
SZ58-3  
• Four independent, individually fused  
siren outputs  
• 500mA load current per output  
• Monitoring of the siren circuits  
• LEDs indicate activation and faults of  
siren circuits  
• Activation by means of actuation  
outputs or external switches  
Description  
The Siren Connection Module SZ58-3 is installed in Fire  
Detection Control Panels Series BC216, BC016 and  
BC06 for connecting acoustical or optical signalling  
devices (e.g., sirens) to four independently actuatable  
circuits with line monitoring. The siren circuits are indi-  
vidually protected by means of self-healing electronic  
fuses. The activation of the siren circuits is carried  
out by the control panel or manually by means of swit-  
ches.  
creased current demand, through an external power  
supply. The supply of the siren circuits is automatically  
monitored for undervoltages.  
The componentry is equipped with four fault detection  
outputs which report the fault condition of power supp-  
ly and siren lines to the control panel.  
For each output there are separate LEDs for indication  
of fault and activation.  
The signalling devices can be supplied either directly  
by the fire detection control panel, or, in case of in-  
The siren connection module is mounted on a bracket  
inside the housing of the fire detection control panel.
