have to be above the fire alarm level to activate fire alarm in EBL128.
(This results in approx. 7 seconds alarm delay).
The same is valid for pre-warning only it is a lower level than for fire
alarm.
The same is valid for heavy heat alarm only it is a higher level than
for fire alarm. Heavy heat alarm will be saved in the event log.
The fire alarm, pre-warning and heavy heat alarm level respectively
can be set via Win128, see chapter "Alarm Algorithms", page 121.
"Pre-warning", "Fire Alarm" and "Heavy Smoke Alarm" can activate
programmable outputs respectively, see chapter "Control expression",
page 69. See also the EBL128 Operating Instructions for more
information.

Class A1 algorithm

Conforms to Class A1.
Typical / max. application temperature 25 / 50° C.
Max. / min. static response temperature 54 / 65° C.
The algorithm is as follows:
For a rate-of-rise < 4° C per minute:
Fire alarm level is 56° C.
Pre-warning level is 46° C.
Heavy heat alarm level is 90° C.
For a rate-of-rise > 4° C per minute:
Fire alarm level is 46° C.
Pre-warning level is 36° C.
Heavy heat alarm level is 90° C.
The biggest difference between the class A1 and A2 algorithms is that
the class A1 algorithm will detect a fast temperature rise (rate-of-rise
> 4° C per minute) faster than the class A2 algorithm.

Class A2 S algorithm

Conforms to Class A2 S.
Typical / max. application temperature 25 / 50° C.
Max. / min. static response temperature 54 / 70° C.
The algorithm is as follows:
Fire alarm level is 60° C.
Pre-warning level is 50° C.
Heavy heat alarm level is 90° C.

Class B S algorithm

Conforms to Class B S.
Typical / max. application temperature 40 / 50° C.
Max. / min. static response temperature 69 / 85° C.

No other heavy heat alarm information if not an ext. FBP with printer is
available. If so, the heavy heat alarm information will also be printed out.
