A method of calibrating an optical detector includes affixing a calibration material to a first surface of the optical detector and calibrating one or more parameters of the optical detector using the calibration material.

A sounder apparatus 100 includes a sounder 110 having at least two volume settings, at least one detector 120, a micro-controller wherein the micro controller is configured to receive an input signal from the at least one detector 120, and to control the volume setting of the sounder based on the input signal.

Systems and methods are provided for enhanced alert generation based on real-time manipulation of datasets. An example method includes accessing datasets including a plurality of rows each indicating a plurality of values. Occurrences of alert definitions are monitored via applying the alert definitions to the datasets, the alert definitions specifying expressions utilizing one or more of the values, with an occurrence of an alert definition indicating satisfaction of the specified expression and causing an associated alert to be generated for evaluation. Presentation of an interactive user interface associated with customizing alert definitions is caused. The interactive user interface presents a first visual portion, the first visual portion enabling specification of an expression for a customized alert definition. The interactive user interface presents a second visual portion, the second visual portion comparing occurrences of an existing alert definition with occurrences of a customized alert definition specified in the first visual portion.

A method of calibrating an optical detector includes positioning a calibration block relative to the optical detector and determining a first calibration point of the detector using the calibration block.

A component 10 for use in an alarm system includes a component controller 12 and an offline configuration module 14. The offline configuration module 14 includes a passive RFID tag and is configured to receive and store an indication of at least one configuration parameter wirelessly transmitted to the configuration module. Upon initialisation of the component 10, the component controller 12 operates the component 10 in accordance with one or more protocol determined by the at least one configuration parameter indicated by the indication stored by the offline configuration module 14.
