4.2.3 Setting the Address on Loop Units
CAUTION!
Take care to set appropriate addresses for all loop units.
A fault alarm concerning a wrong loop unit address has to be dealt with promptly. A
correct address is essential to communicate alarms from the loop unit to the central
unit.
In order to become operational, all addressable loop units such as detectors, manual
call points, etc. that are connected to the loop module must be given an address
from 1 to 150 according to the definition of the loops in the project specific
documents or drawings.
NOTE!
Loop units connected to a single physical loop-line must be given unique addresses.
