Embodiments described herein can account for sensor drift by adjusting a clear air offset value. | 02-11-2016 |
20160049059 | RECREATIONAL SMOKING MONITOR SYSTEM FOR USE IN OCCUPIED SPACES - A system detects presence of particles in the air of guest rooms of facilities such as motels and hotels for example that indicate that guests are engaged in recreational smoking. The system provides an indication to the facility manager of such behavior. | 02-18-2016 |
20160071386 | DETECTOR UNIT AND SENSING CHAMBER THEREFOR WITH MATTER RETENTION MEMBER AND METHOD FOR MAKING SAME - Embodiments disclosed herein provide a detector unit and sensor chamber with matter retention member and method for making the same. In one embodiment, a smoke chamber can include a detection circuitry member having a surface, a particle trapping member mounted to the surface, and a chamber coupled to the detection circuitry member. The chamber can include a planar member, and several baffles extending away from the planar member in the direction towards the detection circuitry member and disposed around a periphery of the planar member, wherein a distal end of each baffle interfaces with the particle trapping member. | 03-10-2016 |
20160071387 | FIRE SAFETY SYSTEM - A fire safety system is provided. The fire safety system is adapted for waking a sleeping person from a bed when detecting a predetermined level of smoke in a space occupied by the bed, actuating a nearby egress, and then leading them to and through said nearby egress. The fire safety system may provide an alarm system including visual, audio and vibratory delivery mechanisms for awaking the sleeping person. The fire safety system may provide a lighting assembly to guide the wake person to the egress. The fire safety system may provide an actuating assembly operably coupled to at least on locking assembly mounted to the egress so that the actuating assembly may move an egress covering from a locked position to an unlocked position and then from a closed to an opened position. | 03-10-2016 |
20160086468 | IMPROVEMENTS IN AND RELATING TO ASPIRATING SMOKE DETECTORS - Improvements in and Relating to Aspirating Smoke Detectors Disclosed is an aspirating smoke detection system comprising: at least two different types of detector; and a processor operable to receive signals from the at least two different types of detector, and to determine an alarm status, wherein the alarm status is one of: an all clear status; a critical status; and a status intermediate between the all clear status and the critical status. | 03-24-2016 |
20160104358 | METHOD AND SYSTEM TO ENABLE SELECTIVE SMOKE DETECTION SENSITIVITY - There is provided a method to enable selective smoke detection sensitivity onboard an aircraft. The method has the step of installing one or more sensitivity selectable smoke detector assemblies. The method further has the step of electrically or wirelessly coupling the one or more sensitivity selectable smoke detector assemblies installed onboard the aircraft to one or more sensitivity selector controls installed onboard the aircraft. The method further has the step of selecting an alarm setpoint sensitivity level from two or more alarm setpoint sensitivity levels for each of the one or more sensitivity selectable smoke detector assemblies, based on sensitivity level determination factors of one or more of a mission type of the aircraft, a cargo type on the aircraft, a compartment zone specific area type on the aircraft, and an occupancy state on the aircraft. | 04-14-2016 |
20160140822 | System and Method of Airflow Monitoring for Variable Airflow Environments - A method of operating an aspirated smoke detector includes providing an ambient condition detector, establishing a first flow baseline for the detector, and, establishing a second, lower, flow baseline for the detector. A selected airflow is sampled, and determining if the airflow sample should be compared to the first flow baseline or the second flow baseline, and, responsive thereto determining if a trouble indictor should be generated. | 05-19-2016 |
20160140823 | EVACUATION GUIDANCE NOTIFICATION DEVICE AND SYSTEM - The present invention relates to an evacuation guidance notification system that can detect a fire, can provide notification, can provide guidance on an evacuation route, and can re-ensure a field of vision. The evacuation guidance notification system includes an evacuation guidance notification device installed on a banister post at an edge of a staircase, and the evacuation guidance notification device includes a device housing including a display window, a speaker, a beam output unit, an LED unit, a sensor unit, a control unit, a power unit, a communication unit, and an evacuation direction guidance unit. Furthermore, the device housing constituting part of the evacuation guidance notification device may further include a communication unit configured to communicate with the outside and a control room composed of a computer for controlling the evacuation guidance notification device, and the control room may remotely control the evacuation guidance notification device via the communication unit. | 05-19-2016 |
