6.3. Function “Logical AND” of two lines
The function
Logical AND
gives the opportunity to form the following dependence between two
lines: the fire control panel will enter Fire condition, phase Fire condition stage I, using each of the line
(or both of them) upon activation of fire detectors in both lines.
The function does not affect manual call points. Upon activation of a manual call point (value of
the line current between Fire condition stage II and Short circuit) in a line, dependent on function
“Logical AND”, the fire control panel will enter Fire condition stage II in this line.
Upon activation of automatic fire detector (value of the line current between Fire condition stage I
and Fire condition stage II) in a line that is in Logical AND dependency by another line the fire control
panel will enter
−
Pre-Fire condition in this line – if there is no activated automatic fire detector or manual call
point in the other line;
−
Fire condition, phase Fire condition stage I in this line – if there is an activated manual call
point in the other line, i.e. the fire control panel has already entered Fire condition, phase Fire
condition stage II in the other line;
−
Fire condition stage I in both lines – if there is an activated automatic fire detector in the other
line, i.e. the fire control panel has already entered Pre-Fire condition in the other line.
Exit from Pre-Fire condition in a line is done automatically only:
−
Upon activation of automatic fire detector in a line that has settled dependence to a particular
line according the function “Logical AND”, within 60 s after entering Pre-Fire condition, the fire
control panel enters Fire condition stage I in both lines;
−
Upon activation of manual call point in the line that has settled dependence to a particular line
according the function “Logical AND”, within 60 s after entering Pre-Fire condition, the fire
control panel enters Fire condition stage I in this particular line, and Fire condition stage II in
the first line;
−
Upon increased current value in a line within the limits between current values for Fire
condition stage II and Short circuit the fire control panel enters Fire condition stage II in this
line;
−
Where the 60 s of Pre-Fire condition expire and none of the above mentioned three conditions
is carried out, the fire control panel exits Pre-Fire condition in this line and is reset – the power
supply is interrupted for 3 s thus the activated automatic fire detectors in this line shall be
reset.
To settle dependence of two lines on function “Logical AND”, set the parameter “Logical AND” in
one of the lines. (see section 14.2.2).
When using the “Logical AND” in two lines, we recommend one of the two methods:
−
Outputs for fire condition shall be associated to one line only, where manual call points, if
necessary, are already integrated;
−
The same outputs for fire condition shall be associated to both lines (equal for both Fire
condition stage I and II); in this case manual call points can be integrated in both lines.
6.4. Conditions of the fire control panel
FS5100 monitors the fire alarm lines by consecutively scanning their condition. Depending on the
current value, the line can be in normal condition, in fire condition or in a fault condition (short circuit
or break). Simultaneously, a constant control over the controllable outputs of fault condition (short
circuit or break) is being carried out.
The fire control panel FS5100 operates in nine basic modes: Duty Mode, Fire Condition, Pre-Fire
Condition, Fault Condition, Disabled Component Mode, Test Mode, Information and Control Mode,
SetUp Mode and Remote Control Mode.
In each moment the control panel can be in one or in a combination of these conditions: Fire
Condition, Pre-Fire Condition, Fault Condition, Disabled Component Mode, Test Mode and
Information and Control Mode. In Information and Control Mode text messages for other conditions
are being suppressed. Every time the fire control panel enters Fire Condition or Fault Condition, it
exits Information and Control Mode.
Duty Mode, SetUp Mode and Remote Control Mode cannot be combined with another condition:
−
The fire control panel enters Duty Mode after it has exited all other modes;
−
When the fire control panel enters SetUp Mode or Remote Control Mode it exits all other
conditions.
