    摘要： An aspirating detection system for detecting a fire event in a monitored environment, a method of determining when an aspirator for an aspirating detection system requires maintenance, and a method of calibrating a control module for an aspirating detection system are provided.
    The aspirating detection system (1) comprises an aspirator (2) for sampling air from the monitored environment (100), and a vibration sensor (3) configured to monitor a vibration signature of the aspirator (2). The aspirating detection system (1) may further comprise a control module (4) in communication with the vibration sensor (3). The control module (4) may be configured to determine if the aspirator (2) requires maintenance based on the vibration signature of the aspirator (2).

    摘要： A combined fire suppression and detection system is described. The system comprises a fire panel 12 having a loop driver. A combined detection and suppression loop 18 is connected to the loop driver. A plurality of fire detection devices 14 and a plurality of fire suppression devices 19 are coupled to the detection and suppression loop 18. The fire suppression devices 19 comprise multiple sprinkler devices 19, each of the sprinkler devices 10 comprising a sprinkler bulb 100 and a circuit 120. The circuit 120 of the sprinkler device 10 is detectable via the fire panel 12 using the detection and suppression loop 18 in order to provide information from the sprinkler device 19 to the fire panel 12. A example method of use of the system includes testing of the system in order to ensure that the fire detection and/or fire suppression devices are correctly installed and/or are working correctly by using the fire panel 12 to obtain information from the circuits 120 of the sprinkler devices 19 in order to check that the sprinkler devices 19 are correctly installed, that installed sprinkler devices 19 are of the correct type and/or to identify sprinkler devices 19 that have been tampered with or otherwise damaged.

    摘要： Devices, methods, and systems of a self-testing duct environment detector are described herein. One self-testing duct environment detector system includes a first portion to be mounted outside of a duct, the first portion having a detector housing with a space therein, the space having a detector with a sensing chamber and a self-testing sensing apparatus therein, wherein the self-testing sensing apparatus determines whether airflow through the detector housing is above a threshold and a second portion and third portion each configured to extend into the duct, wherein the second portion has at least one inlet aperture formed therein and wherein the third portion has at least on outlet aperture therein.

    摘要： A theft detection device, for coupling to a merchandise product, includes a housing with a first end of a conductive strap attached to the housing. The housing has an opening for a second end of the conductive strap. The conductive strap secures the theft detection device to the product, and activated when the second end of the conductive strap is inserted into the opening. A light sensor, within the housing, senses the amount of light shining on the detection device. A motion sensor, within the housing, senses movement of the detection device. An emitter, within the housing, provides audio signals to a user. A microcontroller, within the housing, is coupled to the light sensor, the motion sensor, and the emitter. The emitter emits an alarm based on data from the light and motion sensors. The emitter emits an alarm when the conductive strap is cut or loosened from the product.
