Abstract: A control system for silencing an alarm signal of an alarm device comprises a sensor to receive the alarm signal, an input interface for an operator instruction to silence the alarm signal, and control logic to silence the alarm signal. The control logic determines if the alarm signal exceeds a signal threshold indicative of the proximity of the alarm device. If the signal threshold is not exceeded, the control logic prevents the silencing of the alarm device. The control system provides a silencing mechanism that allows remote actuation while requiring a user to be close enough to the alarm device.

Abstract: A remote alarm monitoring system (10) for recording and processing alarm event data. The alarm system (10) comprises one or more alarm devices (12) in connection with an interface (14), wherein the interface (14) is configured to receive alarm event data; a server (18) in communication with the interface (14), wherein the server (18) is configured to receive and process alarm event data from the interface (14); and one or more networked client devices (22) in communication with the server (18), wherein the server (18) is configured to transmit a message to the networked client device (22), said message based upon the processed alarm event data.

Abstract: An alarm for detecting radiation and/or pollutants such as smoke, carbon monoxide or the like, the alarm comprises: an alarm circuit (12) including detection means (14) for detecting the radiation and/or pollutants, and an audible alarm (16); a power supply circuit (24) connectable to an external AC power supply for supplying standby power to the alarm circuit (12); and a battery (20) for supplying power to the audible alarm (16) when the alarm is energized. The power supply circuit (20) is configured to supply current to the alarm circuit (12) at a level less than that required to energize the audible alarm (16).

Abstract: An alarm for detecting radiation and/or pollutants such as smoke, carbon monoxide or the like has a housing (500), an alarm circuit (400) including a detector (DET1) for detecting said radiation and/or pollutants, first electrical connections (PL1, PL2) connectable to an external power supply for supplying power to the alarm circuit, and a control circuit (300) responsive to receipt of a preselected number of pulses over a preselected time period to apply a preset control signal to the alarm circuit (400). The alarm circuit (400) is responsive to the preset control signal to reset or test the alarm in dependence on the preset control signal.
