Panasonic Electric Works Nordic ABMEW01090 Rev: 3 EBL128 Planning Instructions V1.1.x822. pre-warning will be activated at a lower level (smaller offset)than for fire alarm, i.e. pre-warning will be activated before firealarm will be activated.3. heavy smoke alarm will be activated at a higher level (biggeroffset) than for fire alarm, i.e. heavy smoke alarm will beactivated after fire alarm has been activated. Heavy smoke alarmwill be saved in the event log.89The pre-warning offset and the heavy smoke alarm level can, for alldetectors, be set in Win128, see chapter "Alarm Algorithms", page121. See also Win128 help.The fire alarm offset can, for all detectors, be set in Win128, seechapter "Alarm Algorithms", page 121. See also Win128 help.NOTE! Changing these parameters will affect the sensitivity anddetection time and should be done by authorised personnel only!!!!!In addition, a special password is required to change the fire alarmparameters."Pre-warning", "Fire Alarm" and "Heavy Smoke Alarm" can activateprogrammable outputs respectively, see chapter "Control expression",page 69. See also the EBL128 Operating Instructions.13.1.5 Alarm algorithm / Alternative alarm algorithmAlarm algorithmIn order to secure real alarms and reduce nuisance alarms90, sixdifferent alarm algorithms are available. See Figure 17., page 85.The alarm algorithms are based on: Normal, high or low sensitivity Normal (15 sec.) or slow (35 sec.) detection time (alarm delay)Normal sensitivity. 3.0 % smoke obscuration per meter is required toactivate fire alarm (i.e. fire alarm offset=30). This is default in theN-15 algorithm and should normally not be changed.High sensitivity. 2.4 % smoke obscuration per meter is required toactivate fire alarm, i.e. less fire alarm offset than for normalsensitivity. High sensitivity can be used when an "early" fire alarm iswanted.Low sensitivity. 3.6 % smoke obscuration per meter is required toactivate fire alarm, i.e. a higher fire alarm offset than for normalsensitivity. Low sensitivity can be used to get an extra delay time inorder to reduce nuisance alarms90 but might not fulfil the EN54-7specifications.week average sensor value is re-calculated (and adjusted) the fire alarm levelwill also be adjusted. The detector sensitivity is accordingly constant.89 No other heavy smoke alarm information if not an ext. FBP with printer isavailable. If so, the heavy smoke alarm information will also be printed out.90 So called false / unnecessary alarms.
