LST SZ58-3 specifications Siren Connection Module, 500mA load current per output, Description

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.

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.
