摘要: A security system continuously monitoring a plurality of spatially diverse events which are reportable to a central monitoring facility, the system including a controller for sequencing the performance of reporting and monitoring tasks according to the requirements of the events. The system also performs the tasks according to a predetermined priority, in particular, alarm message queuing. In addition, alarm conditions and system operation are verified by specified communication procedures and redundancies. Furthermore, system communications capabilities include keyboard entry and output display and an interrupt facility.

摘要: Zone indication is provided for a facility monitoring and control system by providing the system's sensors and control unit with counters which are simultaneously incremented with clock pulses delivered to the sensors via the multi-wire interconnect cable from the system's control unit. Each sensor output circuit has enabling circuitry connected, as with jumper pins, to a counter output corresponding to a predetermined number or count, and this number or count identifies the sensor. In one embodiment, each sensor output is enabled only during the occurrence of the corresponding count or number from its counter as the counters are incremented through their cycle. When the sensors are used to sense alarm conditions, the sensor sending an alarm signal is identified when an alarm condition signal exists simultaneously with a particular count from the counter at the control unit, with the particular count indicating which sensor is sending the alarm signal. When zone indication is utilized in conjunction with remote data gathering, data is transmitted between counter clock pulses. Should transmission of complex data be required, the counter clock pulses are inhibited and complex data is then read out from the sensor actuated when the counter clock pulses are inhibited, with the complex data read out at a rate governed by a different type of pulsed signal transmitted to the sensor. In one embodiment, zone indication signals are made compatible with sensor control signals so as to establish compatibility with previously installed in-place systems. This greatly facilitates retrofitting existing systems with non-home-run zoning.

摘要: An optically-based coded card identification system is provided in which a card having an access code defined by adjacent differently-polarized elements used in a transmissive or reflective mode is interrogated through a deep red or near infrared transmissive filter as the card is pased by a source of illumination. The use of polarization coupled with the adjacency of the differently-polarized elements makes the code nearly invisible to the naked eye, with the code being made more invisible due to the low visible light transmission of the filter on the face of the card. In one embodiment, coding for the cards is provided by overlying layers of material polarized in different directions, with portions of the layers provided with offset apertures so that light through an aperture in one layer is polaried by an unapertured portion of the adjacent layer immediately thereunder. Alternatively, the same coding effect may be achieved by providing two differently stretched overlying layers of specially prepared transparent material, overprinted front and back with offset iodine patterns, with the iodine causing a polarization characteristic to be imparted to the material at the overprinted area to provide the access code. In one embodiment, the coding elements are arranged in two rows defining complementary codes such that areas of complementary polarizations are simultaneously decoded to provide complementary signals for increasing security and the signal-to-noise ratio for the system. In a further embodiment, an unpolarized detector coupled to a pulsed output detector is used to detect the pulses produced by the light and dark areas of a bar code provided by ordinary printing of a bogus card and to inhibit access upon detection of such a bogus card.

摘要: A card reader operated in proximity to secured area control point including an operating system therein to provide multiple operating modes. The card reader is operable to provide access to a secured area by entry of an identification code, which is read by the card reader, or entered to the keyboard. The user will be granted access to the controlled area when the user access requested corresponds to the level of access provided by the identification codes presented. The card reader has a programming mode, to allow a station manager to program the reader for presenting a programming code. The card reader system also has a degraded mode of operation, which allows user access after power fail and reader restart. A keypad having an interchangeable faceplate is used for all three modes of operation to provide communication and programming with the reader by the system user. The faceplates are selected to provide labels only for the active keypad areas, and to prevent disclosure of proprietary programming and service information to unauthorized individuals.
