Abstract: A tool for performing diagnostics on a fire detection system includes an induction coil which includes two halves that may be selectively opened and closed to surround a wire in the system and sense current through the wire. A diagnostic module and a conduit provide communication of data of the sensed current between the induction coil and the diagnostic module. The diagnostic module is configured to decode the data to interpret communications sent through the wire.

Abstract: A chamberless smoke detector includes a source laser, a grating coupler, a transmitting optical phase array, a receiving optical phase array, and a processing unit.

Abstract: An electrical shut-off device (10) is provided and includes a housing (11), first and second inputs (12, 13) and an output disposed on the housing, a transmission/reception (T/R) module (14) coupled to the first input, an input device (15) coupled to the second input, an electrical device coupled to the output and a processor (20). The processor is in signal communication with the T/R module, the input device and the electrical device via the first and second inputs and the output, respectively. The processor is configured to issue an instruction via the T/R module and to take an action relative to the electrical device responsive to a signal being received by the T/R module and to take an additional action in accordance with an actuation state of the input device.
