It is necessary to calculate current consumption figures for the system in standby (mains fail) and alarm
conditions in order to select the correct battery capacity.
3.1 PANEL CURRENT
Details of panel currents for standby and alarm are shown in the 6300 specification later in this manual.
3.2 LOOP CURRENT
Figures for the loop device current for battery capacity calculations are contained in tables 2, 3 and 4. These
provide details of the quiescent and alarm currents of both the addressable and non-addressable loop devices.
Note: -
1. Loop isolators, devices that isolate sections of the loop if short circuit wiring faults occur, are available
as separate units. Some ‘6000 series’ devices contain an isolator. Check device literature.
2. When using Zone interfaces the current per detector / sounder must be added to the current requirement
of the Interface Units (refer to note 2 of table 3).
3. The alarm loop current figures may differ from the figures quoted in other Protec literature. The figures
here assume a limit on the number of devices lighting their fire led so this reduced led current is
averaged across all the loop devices.
