The following limitations apply to zone doubling:
1. Only normally closed contacts (n/c) may be used.
2. If the zone input to the panel is short or open circuited at the
panel, both the zone and its double will be violated.
3. If the 12K resistor is ìopen circuitedî the primary
zone will indicate a violation i.e. assuming zone 8 is doubled in
this case zone 8 will be indicated as violated.
4. If the 4K7 resistor is ìopen circuitedî the secondary
zone will indicate a violation i.e. assuming the example in 3 above
zone 16 would indicate the violation.
5. The colour codes for the 4K7 and 12K resistors are shown in
Figure 4.

The box tamper input does not require an end-of- line resistor and
requires a normally closed contact.
