OPERANDS TYPE 1 (CONTINUED)
Notes:
1. When entering numbers, leading zeros need not be entered.
2. Alarm and Fault refer to the latched status for a latching zone and the current status
for a non-latching zone.
3. None of these zone tokens are affected by the programming of a zone as MAF
mapped, non-MAF or status only.
4. The circuit input refers to the "debounced" circuit input prior to the 2.3 second filter
and zone "latch". That is, it takes 80-240 milliseconds to change state, is a non-
latching condition, and is independent of zone programming or isolation (including
the automatic isolation in Auto-Reset mode). Refer also to Section 7.4.10.
WARNING
The zone operands ZnD (detector operated) and ZnM (MCP operated) can return a value
which is not the true condition of the circuit input in a number of situations as follows:
1. During zone reset (other than AVF reset or Auto-Reset mode reset) the ZnD and
ZnM operands will be the value that existed at the start of the reset. This includes
the 2 second post reset delay, a total of 7 seconds. After this they will be the current
state of the circuit input. This is true only for V1.10 software onwards. For earlier
V1.0X versions of software ZnD and ZnM are both FALSE for the duration of the
reset.
2. During AVF reset and Auto-Reset mode reset the state of the circuit input is forced to
be B1 (Band 1) during the actual 5 second/15 second circuit reset and at the end of
this period may temporarily be any of the values B1, B2, B3, B4 or B5 until the circuit
and detectors power up again.
Thus the operands ZnD and ZnM may be true during these times depending on the
programming of the circuit.
Band B2 always maps to detector operated/alarm. Bands B1 and B3 may be
programmed to map to any of MCP operated (instant alarm), Detector Operated
(alarm), fault and normal. During AVF Reset and Auto-Reset mode reset the tokens
ZnD and ZnM will follow the state of the circuit. E.g. If B1 is programmed as instant
alarm then ZnM will return true during the reset when the state of the circuit is B1.
3. During System Test and Auto-Test circuit alarm testing, any circuit which has an
alarm test applied to it will be in band B3. Operands ZnD and ZnM will return true or
false according to the programming of band B3.
Note that not all zones are tested by System Test and Auto-Test. Zones which are
not tested include:
1. Isolated zones.
2. Zones which are already in alarm or fault at the start of the test.
3. Status only zones.
4. Zones where the current input state is B1 and B1 is programmed to be
normal.
4. During zone alarm test the ZnD operand will return true if the test operates correctly.
