    摘要： The present invention is an alarm system comprising an alarm handset (10) having a housing (30), a detector circuit (100) having means (102, 104) for receiving a preselected signal from a remote transmitter (40) and generating a first detection signal in response thereto, first sensing means for sensing change in a preselected parameter of the handset, warning means (300) for generating a warning signal, alarm means (400) for generating an alarm signal and control means (500) responsive to receipt of the detection signal to activate the alarm means (400). The control means (500) is operable to activate the warning means in response to at least one of receipt of the control signal and sensing of the change in the preselected parameter of the handset.

    摘要： The present invention relates to a system for determining particle transmittance Tx of a filter for use with a particle detection system to provide a filter warning for aspirated particle detection systems by detecting a level of first particles having a size indicative of smoke particles and which pass through the detection system; determining an integrated smoke hours value by integrating the detected level of first particles over time; estimating the smoke particle transmittance Tx of the filter by applying a predetermined weighting operation to the integrated smoke hours value. An empirical measure of a filter's particle transmittance Tx, due to at least first particles having a size indicative of smoke particles may be achieved by way of integrating a level of such first particles passing through a particle detection system over time to determine the proportion of smoke particles arrested by a filter, "integrated smoke hours". The "integrated smoke hours" value is, generally, a measure of cumulative filter blockage over time by smoke like particles and is a measure of a given amount of ambient smoke detected and recorded by a smoke detector system and integrated over the time of exposure of the smoke detector system to the ambient smoke. Using this method it is not necessary to infer the actual "filter load" per-se or, the actual particle mass trapped in the filter.

    摘要： A hazard detector has an electronic circuit with a start-up program for causing emission of a local indicator signal, such as a flashing signal from a LED, if power and ground terminals of the detector are connected with proper orientation, i.e. polarity, to power and ground lines of a power supply. Through this means, a person installing the hazard detector can tell immediately after connection if the detector has been connected with proper orientation, and avoids the need for introducing a hazard such as heat or smoke to test the operation of the detector. A variation uses a more sophisticated program that disables, during a test mode, complex filtering algorithms that are used by detectors to block false alarm signals; if such filtering is not disabled, impedes normal testing of the detectors.
