Embodiment Construction
[0027] In the following description, specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from this description, and those skilled in the art can make similar extensions without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.
[0028] refer to figure 1 , 2 As shown, the present invention provides an active aspirating fire detector fire alarm confirming device, comprising:
[0029] The sampling pipeline 2 is used to collect air samples through the sampling holes on the sampling pipeline;
[0030] The active aspirating fire detector 1 is used to measure and analyze the smoke concentration in the collected air samples, and send out early warning signals and fire alarm confirmation signals;
[0031] The loop line 5 or the monitoring line 4 is used to transmit the e...

The invention discloses a fire alarm confirmation device of an active aspirating fire detector. The device comprises a sampling pipeline for collecting an air sample through sampling holes in samplingpipelines, the active aspirating fire detector used for measuring and analyzing smoke concentration in the air sample, emitting a warning signal and a fire alarm confirmation signal, a circuit line or monitoring line used for transmitting the warning signal and the fire alarm confirmation signal to an fire automatic alarm system host when the smoke concentration reaches an alarm threshold a and an alarm threshold b, and the fire automatic alarm system host used for receiving the warning signal and an alarm signal. The invention also provides a fire alarm confirmation method of an active aspirating fire detector based on the confirmation device, while the stable operation of the system is ensured, the fire alarm automatic confirmation of a fire automatic alarm system can be effectively realized, the device has strong universality, the system equipment cost and construction cost are greatly saved, the system debugging is facilitated, and the later system maintenance workload is simplified.
Description
technical field [0001] The invention relates to the field of building fire prevention and fire protection, in particular to a fire alarm confirmation device and method for an active aspirating fire detector. Background technique [0002] Since the active aspirating fire detector has the characteristics of initiative, flexibility and multi-level alarm, it is more and more used in the automatic fire alarm system in various important buildings. In the automatic fire alarm system, the fire alarm confirmation is often realized through the "AND" logic of the signals of two independent alarm trigger devices, so two active aspirating fire detectors are required to achieve the purpose of fire alarm confirmation. Since the active aspirating fire detector equipment is relatively expensive, the fire alarm confirmation is realized by two active aspirating fire detectors, the cost is high, and the fire alarm confirmation method is relatively complicated. Therefore, it is a problem that n...
