IS Isolator Recommendations
BR385 Sounder alone IS Isolator Recommendations
Option 1 – Single Sounder Installation: The BR385 Sounder requires a single intrinsic safety barrier with safety/entity parameters not exceeding the following values: Uo/Voc=28V, Io/Isc=93mA, Po/Po=660mW
Suitable Barrier: GMI D1048S /D1049S / D5048S / D5049S using output “C” terminals in each case.
Option 2 – Multiple Sounders, Use of Multi-Channel Barrier for Economy:
Suitable Barrier: GMI D1042Q (quad channel) with each output separately powering an individual BR385 sounder.
Note that while each sounder has its own dedicated barrier channel, a complete failure of the barrier module will affect all alarm notifications associated with it.
Sounder and Beacon IS Isolator Recommendations
Option 1 – Mutual Two-Wire Connection: The BA386 Beacon & BR385 Sounder Combination may be powered from a single intrinsic safety barrier providing 16VDC @ 35mA and with safety/entity parameters not exceeding the following values: Uo/Voc=28V, Io/Isc=93mA, Po/Po=660mW.
Suitable Barriers: P&F KFDO-SD2-Ex1.1045; MTL5025
Note that failure of the single barrier will negate both alarm notification modes.
Option 2 – High Integrity Four-Wire Connection, Beacon and Sounder Powered Separately:
The BA386 Beacon requires a single intrinsic safety barrier with safety/entity parameters not exceeding the following values: Uo/Voc=32V, Io/Isc=110mA, Po/Po=800mW.
Suitable Barrier: GMI D1048S /D1049S / D5048S / D5049S using output “B” terminals in each case.
The BR385 Sounder requires a single intrinsic safety barrier with safety/entity parameters not exceeding the following values: Uo/Voc=28V, Io/Isc=93mA, Po/Po=660mW. Suitable barrier: GMI D1048S / D1049S /D5048S / D5049S using output “C” terminals in each case.
Note that the failure of one barrier will leave the other alarm notification mode working.
Option 3 – Multiple Beacon & Sounder Combos, Use of Multi-Channel Barrier for Economy:
Suitable Barrier: GMI D1042Q (quad channel) with each output separately powering either a beacon or a sounder. Under no circumstances may two barrier channel outputs be connected in parallel to power one beacon-sounder combination.
Note that while each beacon and sounder has its own dedicated barrier channel, a complete failure of the barrier module will negate all alarm notifications associated with it.
