Connection interface CB-ST New
Interface for connecting ST-3s column beacon with contact outputs of control modules
The CB-ST interface is designed to connect a column sounder type ST-3s with the contact outputs of control modules. It makes it possible to easily configure the parameters of the column optical/acoustic signaling device by setting switches/jumpers.
It is possible to:
- setting the illumination of 3 LED lights in continuous or flashing mode;
- switching on the built-in siren and assigning its operation to the corresponding state ALARM1, ALARM2, ALARM3 and/or EMERGENCY;
- setting the operation of the siren with a continuous or intermittent signal;
- setting the EMERGENCY condition as a flashing green light, with or without siren sound.
The interface is housed in a sealed terminal box. It is designed for installation outside gas or dust explosive areas.
Features
- 24V= power supply (green light confirming the presence of voltage);
- power circuit fuse 1A (required for ST-3s/Ex control);
- a set of 4 jumpers for setting the function of flashing lights, siren switching on and pulsing, and the method of signaling the EMERGENCY status;
- a set of removable connectors for connecting the 7-core cable from the column siren and the power cable (2 wires) and connecting to the contact outputs of the control module (4 wires);
- connection of 1 pc ST-3s siren or 1 pc. ST-3s/Ex in any configuration;
- parallel connections of up to 3 ST-3s sirens with light/silence only in continuous mode;
- choke-free, sealed housing (IP44) with diaphragm vents.
