Overcoming Voltage Drop
There are several ways to overcome voltage drop:
Use thicker lower resistance cable. Standard 7/0.2 alarm cable
has a resistance of 8 per 100m
Double up on the power connections – this will require using a
6 or 8-core cable rather than a 4-core cable
Install a power supply to power the device locally, remember to
common the two negative connections
Use of pull up resistors
Devices lost from the network, or high levels of network
errors can sometimes be cured using pull-up resistors.
Poor quality cable and/or installation practices are the most
common cause of continued faults with network devices.
The diagram details the type and placement of the resistors.
