• 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.
