Loop loading

(VIG-LPC-EN and COMPACT-LPC-EN)

4188-1075 issue 3_Part 2_08/14

This document shows how to determine the loop load and loop cable length for a Post March 2014 Loop Card 

fitted in a Vigilon panel:

 

 

VIG-LPC-EN   (for use in Vigilon 4-6 loop panels only)

 

COMPACT-LPC-EN  (for use in Vigilon Compact panel only)

A precise battery standby calculation result is obtained using the ‘Battery standby and loop load calculator’ 
tool. The tool can be downloaded from www.gentexpert.co.uk website, accessible to registered users.

Distributed alarm device load 

This is where the alarm load is distributed along the entire length of the loop and when using:

 

1.5mm² cable, the loop length can be up to 2Km with up to 200 devices and up to 400mA alarm current for standard 
mode of loop card operation  / 800mA alarm load for enhanced mode of loop card operation. 

 

2.5mm

²

 cable, the loop length can be up to 2.5Km with up to 200 devices and up to 400mA alarm current for 

standard mode of loop card operation  / 800mA alarm load for enhanced mode of loop card operation.

U

se table 1 to calculate the loop alarm load.

Always use the 

‘Battery Standby and loop load calculator tool’

 to determine loop load and panel battery standby.

Lumped alarm devices load

If the alarm devices are lumped together on a loop circuit then there is a trade off between the number of alarm devices and loop 
cable length possible, which must be calculated.
Use the 

‘Battery Standby and loop load calculator tool’

 to determine  the precise loop length, loop load and panel standby. In 

the absence of the tool a rough method to determine

 loop length and loading only

 is shown here. Use table 1 to determine alarm 

load and respective table 2, 3, 4 or 5 to determine loop length and loop load.
