3.13 Power Source
Each component of the Backsense
®
system must be separately fused but powered from the
same switched power source detailed in section 3.10.
System components requiring individual fuses include:
• BS-OSD-022 ECU
• BS-9000 Sensor Network, (via a single dedicated Brigade power cable)
• Display Monitor
• Secondary devices connected to Trigger Outputs 1 & 2 (if applicable)
• External warning alarm connected to Trigger Output 3 (if applicable)
Only one power input to the BS-9000 sensor network is permitted (via dedicated Brigade
power cable only) and must be suitably positioned within the network to ensure that loading
from all sensors is balanced and excessive voltage drops are avoided.
The BS-9000 sensor network must be adequately powered under all operating conditions. The
installer must verify that any volt drop throughout the network does not cause the supply at the
sensor to drop below the minimum recommended value during operation, (see BS-9000
Installation and Operating Guide for details)
The table below details the maximum fuse rating for each of the above elements of the
system:
