Loop driver module BSD-310/N

Loop driver module with capacity for one detector loop with a maximum of 127 loop units (detectors/I/O modules/sounders). Maximum 99 detectors/call points. Maximum number of loop driver modules per control panel/controller is 6. For Ex zone 2.

The loop driver module functions as a modem for data exchange between the control system and the detection loop. It is easily plugged onto a mounting rail inside the fire alarm control panel BS-420 or the controller BC-420.

1 detection loop for connection of 127 loop units can be connected to each loop driver module. A loop unit is defined as either a point (i.e. a detector or a manual call point), I/O unit or an electronic sounder.

BSD-310/N is for use when there are zone 2 detectors of type EXn on the loop. This is for type /N detectors only.

In addition to its main function, the module provides two important monitoring and security features. The loop resistance on the detection loop is continuously monitored to register a possible break or short-circuit on the detection loop. If a communication failure occurs, a Fail_Safe function is automatically activated. A low-frequency modulation on the loop will be detected, and a separate control output (F/S) will then be activated. The module will automatically detect its own address, no Dip-switch or jumper settings are required.
