➢ Disarming diagnostics Extra disarm chirps are the Tamper Alert. If four chirps are heard when disarming, the system was triggered in your absence. If five chirps are heard, a zone was triggered so many times that Nui­sance Prevention® Circuitry has bypassed that zone. In either case, the status LED will indicate which zone was involved. (See Table of Zones section of this guide.) The system will retain this information in its memory, and continue to chirp four or five times each time it is disarmed, until the next time the ignition key is turned on. ➢ System status chirps The siren will chirp when arming/disarming the system. The pattern of chirps will audibly report the system's status as described below.
