As more loop devices are added, they are summarised in the “Summary of loop units”
providing information for total quiescent and maximum consumption in the “Properties for

under their respective loops.

Quiescent and alarm current must be added correctly for each brigade unit e.g. Romtec, Tyco ASE, etc. Separate power
supply and batteries may be required.
Totally up to eight 1736 and/or 1728 units might be used.
OWS must be powered from a separate power supply and battery backup.
