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 and Sounders.
The protocol and internal memory are constructed in such a way that there are certain loading rules
which must be strictly enforced.
1. Maximum 200 devices per loop
2. Maximum 60 sounders/beacons/sounder beacons (set low) per loop.
3. Maximum 20 I/O units per loop which assumes each I/O uses 3 output channels;
4. Maximum 120 Output channels based on 2 + 3 above.
Certain devices have been constructed to circumvent these rules ef
fectively ‘fooling’ the panel to
offset some of the totals. The maximum 200 per loop CAN NOT be changed.
