Eaton CF2000 - Loading and Totals

11 Amended: April 22
EMEA Fire Technical Support: DF6000/CF3000 Applications Guide
Loading and Totals
The general rules are that the panel is capable of supporting up to 200 devices per loop; this can be a
combination of Detection, Callpoints, I/O units, Repeaters and Sounders.
The protocol and internal memory are constructed in such a way that there are certain loading rules
which must be strictly enforced.
Maximum 200 devices per loop
Maximum 60 sounders/beacons/sounder beacons (set low) per loop.
Maximum 20 I/O units per loop which assumes each I/O uses 3 output channels;
Maximum 120 Output channels based on 2 + 3 above.
Certain devices have been constructed to circumvent these rules effectively ‘fooling’ the panel to
offset some of the totals. The maximum 200 per loop CAN NOT be changed.
The totals for EN and UL are the same unless specified in the remarks column.

Note 1 – The figure in brackets is a recommended total for these devices, there is currently no
restriction placed in the Loop loader program.
Note 2 – Where total per loop is shown this is a maximum number or a maximum combination with
other output device
