It prevents annoying repetitive trigger sequences due to faulty door pin switche­ s or env­ ir­on­men­tal con­di­tions such as thunder, jack­ham­mers, airport noise, etc. Example If the alarm triggers three times within a 60-minute period and each time the same sensor or switch triggers the alarm, NPC will interpret those triggers as false alarms. After the third trigger, NPC ignores, or by­pass­es, that sensor or switch (along with any other sensors or switches sharing the same zone) for 60 minutes. © 2008 Directed Electronics - All rights reserved. 15
