Product Information Optical Smoke Detector NOM/NOM K 100 LSN PI − 34.62c 5. Device Design The NOM 100/NOM K 100 comprises a detector module and a detector base. The housing is made from impact−resistant ABS plastic. The NOM K 100 is supplied with a dust filter and the appropriate mounting clamp. The detector module contains the photo−electronic part with the light source and the light receiver, a electronic evaluation switching, a wire mesh for insect protec- tion in the smoke entry opening, shielding against electrical interference fields and...
Product Information Optical Smoke Detector NOM/NOM K 100 LSN PI − 34.62c 6. Functional Description Smoke and contamination are measured separately with the NOM 100/NOM K 100. For smoke measurement, a light source sends 15 light flashes through the mea- suring area one after the other at one second intervals.
Product Information Optical Smoke Detector NOM/NOM K 100 LSN PI − 34.62c 6.1. Smoke measurement Inside the black interior housing, a light source (infrared LED) sends light flashes through the measuring area at one second intervals. A photo cell located opposite is trained on the unlit interior wall, below the LED.
Product Information Optical Smoke Detector NOM/NOM K 100 LSN PI − 34.62c 6.2. Contamination measurement Contamination is measured using a different method. A second light source (infrared LED) sends a light flash to the opposite interior wall. If the detector is not contaminated, the light beam is absorbed almost completely by the black interior wall.
Product Information Optical Smoke Detector NOM/NOM K 100 LSN PI − 34.62c 6.3. Monitoring Stages Alarm signaling takes place at different thresholds for smoke and contamination. For smoke The evaluation is made during smoke measurement using the scattered light measured and the resulting current. If specific thresholds, defined in the detector, are exceeded, the detector issues a corresponding message.

Alarm Triggering Alarm triggering when detector is not contaminated Current Alarm Alarm 100% Pre−alarm Pre−alarm Quiescent state value Time If there is smoke or contamination, the current provoked by the photo cell increases. A pre−alarm is issued by the detector if 50% of the alarm current is reached.

Product Information Optical Smoke Detector NOM/NOM K 100 LSN PI − 34.62c 6.5.2. Detector not sensitive enough The detector is automatically switched off if the measured value is approx. 20% below the 0% threshold. Reliable detection of smoke particles is not possible as the detector is no longer sensitive enough.
Product Information Optical Smoke Detector NOM/NOM K 100 LSN PI − 34.62c 6.6. Planning Monitoring/Change in Functionality In addition to the monitoring and message functions, the detector can also be used to call up the analog measured volume in realtime using a special operating mode. These values can be used for later information.

Change in functionality Current Fault Exchange Change in functionality Slight contamination Quiescent state value Fault Time The characteristic curve represents the path of a de- tector that has already been operational for some time. The value has increased slightly due to contamination.
