Planning Instructions Fire alarm system EBL512 G3, V1.1.x
In addition, a special password is required to change the parameters
for fire alarm.
Parameters for heat algorithms
The "alarm" levels are fixed, i.e. there are no offset values. The
sensor values can be 0-200, which is equivalent to 0-100° C. The rise
time and step down gives a rate-of-rise function (used in the A1
algorithm only). See also chapter "Algorithms for analog heat
detectors", page 96.
The following example is for the A1 algorithm for the 3308 detector.
The values for other algorithms and the 4300 detector are different.
Level, pre-warning: Level, default 92 (46° C).
Level, alarm: Level, default 112 (56° C).
Level, heavy alarm: Level, default 180 (90° C).
Rise time: Default 8.
Step down: Default 20.
NOTE! Changing these parameters will affect the sensitivity and
detection time and should be done by authorised personnel only!!!!!
In addition, a special password is required to change the fire alarm
parameters.
Parameters for combined decision algorithm
Offset, see "Parameters for smoke algorithms" above. Level, see
"Parameters for heat algorithms" above. See also "4300", page 41.
The following example is for the Dec algorithm for the 4300 detector.
Offset, pre-warning: Offset value, default 50 (5.0%/m).
Offset, alarm: Offset value, default 58 (5.8%/m).
Level, pre-warning: Level, default 50° C
Level, alarm: Level, default 58° C.
NOTE! Changing these parameters will affect the sensitivity and
detection time and should be done by authorised personnel only!!!!!
In addition, a special password is required to change the fire alarm
parameters.
