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.
