Panasonic Eco Solutions Nordic ABMEW01622 Rev: - EBL128 Planning Instructions V2.0.x99The 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.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 "Class A1 algorithm" will detect a fast temperature rise (rate-of-rise > 4° C per minute) some minutes earlier than the "Class A2algorithm".13.5.2 Class A2 S algorithmConforms 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.13.5.3 Class B S algorithmConforms to Class B S.Typical / max. application temperature 40 / 50° C.Max. / min. static response temperature 69 / 85° C.The algorithm is as follows:Fire alarm level is 74° C.Pre-warning level is 64° C.Heavy heat alarm level is 90° C.The "Class B S algorithm" can be used when the applicationtemperature is "high" (compare with the "Class A1 an A2 Salgorithms).13.6 Self verificationThe analog detectors 430x / 440x in NORMAL mode have a built-inself verification function. The detector's H/W is always supervised bythe detector's S/W and CPU. Every minute, each detector will receivea question from EBL128. If the self verification function has detectedany fault it will be reported back to EBL128. A fault will be activatedin EBL128 and the following fault message will be shown:FAULT: Detector xx-xx →FAULT: Detector techn. address nnn ←
