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.

The signalling devices can be supplied either directly 

by the fi re detection control panel, or, in case of in-

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 siren connection module is mounted on a bracket 

inside the housing of the fi re detection control panel.

•   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
