and Combined Decision algorithm Dec respectively.
Detector: Shortening and Type number (e.g. OPT 4301 = Analog
photoelectric (optical) smoke detector and AMD 4300 = Analog
Multi Detector).
Name: Name of the algorithm (e.g. N-15, Class A1 & Decision).
Normally not changed.
Abbrevation: The algorithm abbreviation (< six characters) as shown
in the EBL128 display, menu H4/U3 (e.g. N-15, A1 & Des).
Normally not changed.

Parameters for smoke algorithms

Offset is a fixed value added to the week average sensor value to get
the "alarm" level respectively, e.g. 1 + offset 30 = 31 = the fire alarm
level (equivalent to 3.1 % obscuration per meter).
The step value gives the alarm delay time to the algorithm
respectively, see chapter "Functions / Services / Features", page 81.
Offset, smouldering: Offset value, default 15 (1.5%/m).
Offset, pre-warning: Offset value, default 22 (2.2%/m).
Offset, alarm: Offset value, default 30 (3.0%/m).
Level, heavy smoke: Heavy smoke level, default 150 (15%/m).
Step value: Default 5.
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 parameters
for fire alarm.

Parameters for heat algorithms

The "alarm" levels are fixed, i.e. there are no offset values. The rise
time and step down gives a rate-of-rise function (used in the A1
algorithm only). See also chapter "Analog heat detectors", page 88.
Level, pre-warning: Level, default 46 (°C).
Level, alarm: Level, default 56 (°C).
Level, heavy alarm: Level, default 90 (°C).
Rise time: Default 4.
Step down: Default 10.
NOTE! Changing these parameters will affect the sensitivity and
detection time and should be done by authorised personnel only!!!!!

The week average value starts at "1" for a new (clean) detector. The very
first average value will be calculated within two minutes (after SSD
download & restart) and thereafter every week. The fire alarm level will be
adjusted or not adjusted every week, depending on if the latest calculated
week average value is the same as the previous, if it has increased or if it has
decreased. The week average value will normally increase very slowly in a
long-time period.
