Roteck's Pattern Detector is a remotely-operated add-on unit that is able to determine certain patterns from the weapon detector, for the purpose of alerting the next level of security in situations where it might not otherwise have been alerted. After installation and connection to any alarm system, the pattern detector is on alert 24/7.
The detector transmits a pre-adjusted high-alert signal to the pattern detector. When a signal is received, the internal beeper sounds and the first stage alarm will trigger. If there is no further high-alert signal detected within the following 30 seconds, the unit will automatically reset and return to idle mode. If there are further high-alert signals within the 30-second time frame, the unit will trigger the second stage alarm. The silent panic alarm will then be triggered after 30 seconds and can only be stopped by pushing the reset button.
