Controlled Relay Module BR3-I for Efficient Fire Safety Automation

Block of controlled relays BR3-I is designed to control various fire automation devices as part of the integrated security system "Strelets-Integral". For data exchange with the ISB segment controller in BR3-I uses a network interface S2. BR3-I has three relay outputs.

For each relay output the BR3-I monitors the integrity of the line to the load and the line to the voltage source that activates the load. BR3-I has three inputs for monitoring the status of fire automation devices. The BR3-I has three inputs (FLT1, FLT2, FLT3).

These inputs can be configured as remote start inputs, as start interlock inputs or as external equipment fault inputs. The state of FLT and DMP inputs is monitored by the resistance of the external circuit.Power supply is provided from an external DC source of 9-28 V with the possibility of controlling the main and backup power supply.
