    Abstract: A fire suppression system has a plurality of tank units (40, 42, 44, 46) each having: a tank body having a first port and an interior for storing at least one of fire suppressant and driver gas; a discharge assembly mounted to the first port and comprising: a discharge valve (50, 52); and a first monitoring switch or sensor (230; 240). A first monitoring unit (100) is coupled to the first monitoring switch or sensor of each said tank unit and configured to communicate with a remote monitoring location. For each of the tank units there is: a second monitoring switch or sensor (260, 280, 290); and a second monitoring unit (340) coupled to said second monitoring switch or sensor and configured to communicate with the remote monitoring location.

    Abstract: A light detection system is provided for association with a light source. The light detection system includes a light detector and circuitry. The light detector includes semiconductor film and phototube devices and is disposed with at least one line-of-sight (LOS) to the light source. The circuitry is coupled to the light detector and the light detector and the circuitry are configured to cooperatively identify a presence and a characteristic of a light emission event at the light source.

    Abstract: A control system of a detection system for measuring one or more conditions within a predetermined area includes a control unit having at least one processor for implementing an algorithm and a fiber harness having at least one fiber optic cable for transmitting light, the at least one fiber optic cable defining at least one node arranged to measure the one or more conditions. A sensor is operably coupled to the at least one node, wherein the sensor receives scattered light associated with the at least one node and generates signals corresponding to the scattered light. A switch is operably coupled to the sensor and to the control unit. The switch selectively provides signals from the sensor to the control unit for processing to determine at least one of a presence and magnitude of the condition within the predetermined area.

    Abstract: An indoor air quality monitoring system (20) is adapted to function within a space (26) utilizing a building subsystem (22), such as a heating ventilation air conditioning (HVAC) unit, configured to control an ambient parameter, such as temperature, humidity or lightning, in the space (26). The system (20) includes an agent detector (30) configured to detect an agent in ambient air, such as smoke, biohazards or particulate matter, and sequentially output an initial agent measurement signal and a subsequent agent measurement signal. A controller (34) of the system (20) includes a processor and a storage media. The controller (34) is pre-programmed with an agent threshold value, and configured to receive the initial agent measurement signal, compare the signal to the agent threshold value, and if the signal exceeds the agent threshold value, then send a command signal (42) to the subsystem (22) to alter the ambient parameter associated with the agent detector, and then receive the subsequent agent measurement signal from the agent detector associated with the altered ambient parameter.
