SenTRI4 fire system

Battery Standby and Loop load calculator tool

The ‘Battery standby and loop load calculator’ tool can be downloaded from

www.smstoolbox.co.uk website by registered users.

Loop Cable length

The loop cable length is defined as the sum of the length of cable used on the main

loop plus that used on all the spur circuits off the main loop having system devices.

Loop device load and length calculations

There can be up to 200 devices on a loop cable of up to 2Km when using Loop Card

(SENTRI4-LPC-EN), where both device count and cable length are dictated by the

number of alarm devices on the loop and how they are positioned, distributed or

lumped together.

What are Lumped and Distributed alarm device loads?

Distributed alarm device load

Where the alarm load is distributed along the entire length of the loop using:

1.5mm² cable, the loop length can be up to 2Km with up to 200 devices.

2.5mm² cable, the loop length can be up to 2.5Km with up to 200 devices.

Lumped alarm device 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, see also loop

card leaflet which can be downloaded by registered users from www.smsfire.co.uk.
