摘要： A detector comprises a housing (1) having a window (3), a measuring and processing unit (2), a source (4) of electromagnetic radiation, a plurality of sensors (7), and a reflector (6). The measuring and processing unit (2), the electromagnetic radiation source (4) and the sensors (7) are mounted within the housing (1). The reflector (6) is mounted outside the housing (1). The reflector (6) is positioned to reflect electromagnetic radiation passing through the window (3) from the electromagnetic radiation source (4) onto the sensors (7) via the window. The sensors (7) are operatively associated with the measuring and processing unit (2) to provide that unit with an input indicative of the level of electromagnetic radiation reaching the sensors.

摘要： A self-monitoring smoke detector comprising a housing (11) defining an internal chamber (12). An optical transmitter (13) is mounted within the housing (11) so as to direct light into the optical chamber (12). An optical receiver (14) is mounted in the housing (11) and in optical communication with the optical chamber (12). The optical transmitter (13) and the optical receiver (14) are so positioned that light from the transmitter cannot directly reach the receiver. Monitoring means is provided, comprising first and second light-scattering means (13a and 14a) positioned respectively in alignment with the transmitter (13) and the receiver (14). The arrangement is such that, in the absence of reflector particles in the optical chamber, light from the transmitter (13) can reach the receiver (14) only after scattering at the first light-scattering means (13a) and then after scattering at the second light-scattering means (14a).

摘要： A method is disclosed for testing the functionality of a sensor (1) of a fire detector during operation thereof. The method comprises applying a current-limited test signal to the sensor (1), the test signal being such that the impedance of the sensor is such as to absorb the current-limited test signal when the sensor is operating normally; and applying the output of the sensor to a test signal detector (7). The arrangement is such that the test signal passes the output terminal of the sensor (1) only when the sensor is not operating normally.

摘要： An interface circuit of a sub-system of a distributed fire detection system having a plurality of sub-systems, wherein the plurality of sub-systems are in communication with each other in a loop configuration to allow data signals to be routed between said sub-systems. The interface circuit connects the internal components of a sub-system to the external bus line connecting all components via at least three input/output ports. It comprises hardware logic components, namely switches and switch controllers listening for incoming data and opening or closing said switches to cause disconnection and connection between said input/output ports accordingly, thereby allowing the routing of data signals to one or more of the other input/output ports. The simpler configurations replaces a routing processor.

摘要： A particulate detector (10) comprises a radiation source (12) arranged to emit radiation in at least first and second predetermined wavebands towards a sampling region (18) suspected of containing particulates, and a detection element (14), shielded from the radiation source (12), and arranged to detect radiation from the sampling region (18) at least first and second instances. The radiation source (12) is such that the emissions in the wavebands temporarily overlap. The detector is such that, at the instances at which the radiation is detected, the relative contributions from the emissions in each predetermined waveband are distinguishable, thereby allowing characteristics of the particulates to be determined. The radiation source (12) may comprise a light emitting diode (24).
