Method and apparatus for the inspection, maintenance and testing of alarm safety systems

摘要

A safety system receives inputs from safety related input devices such as smoke detectors and the like and provides triggering outputs to notification appliances such as bells and the like and/or safety functions such as door releases. To facilitate testing of the input devices the system incorporates a timer operative to disconnect the output devices for a period of time during which testing may be achieved, automatically reconnects the output devices at the end of the time, records the number of triggering outputs received at the outputs during that period.

1. A safety system comprising input devices for ambient conditions operative to generate trigger signals and alarm notification output devices and safety activation output devices normally activated by the trigger signals, which facilitates system testing, the safety system further comprising:
an alarm panel for receiving trigger inputs from at least one of said input devices and operative to generate output signals communicated to said alarm notification and safety activation output devices for activating at least one alarm notification device and/or at least one safety activation device; a temporary disconnect circuit comprising a timer that upon activation precludes the output signals by the alarm panel from being communicated to said at least one alarm notification output device and/or at least one safety activation output device for a predetermined period of time, and, after expiration of the predetermined period, restores communication of the output signals of the alarm panel to at least one alarm notification output device and/or at least one safety activation output device; means for generating trigger signals by the input devices during said predetermined period and a recorder for recording the number of trigger signals generated by said input devices during the period of activation of said timer at the inputs to the disconnected at least one alarm notification output device and/or at least one safety activation output device to provide a test result of the integrity of said system from the input devices to the output devices based on the recorded number of generated trigger signals.
