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 SZ58-3is 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 individually protected by means ofself-healingelectronic fuses. The activation of the siren circuits is carried out by the control panel or manually by means of switches.

The signalling devices can be supplied either directly by the fire 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 supply 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 fire detection control panel.
