Discovery Response Modes
The major goal in designing a detection system is
achieving the best detection performance while keeping the number
of unwanted alarms to a minimum. Unwanted alarms are normally
caused by environmental influences and, generally speaking, the
higher the sensitivity, the more frequent the unwanted alarms.
Each detector in the Discovery range can operate in one of five
response modes. Any of five modes can be selected from the control
panel. Each mode corresponds to a unique response behavior,
which is generally related to it's sensitivity to fire.
Whatever the type of detector, mode 1 will give a higher
sensitivity to fire than mode 5.
Therefore, Discovery detectors set to mode 1 will be most
suitable for environments in which sources of unwanted alarms are
rare, for example cleanrooms and computer labs. At the other
extreme, response mode 5 will be suited to more dusty or smoky
environments such as loading areas where diesel forklift trucks are
operating. Response mode 3 is a general-purpose setting for which
the response is similar to that of the corresponding XP95
detector.
The table below illustrates typical applications and their
modes.
