Embodiment Construction

[0026] Various embodiments of the present invention will be described below with reference to the accompanying drawings. The above-mentioned advantages of the present invention will be more easily understood through the following description.

[0027] figure 1 A structural block diagram of a traditional fire detector is exemplarily shown. like figure 1 As shown, a conventional detector 100 includes a power supply 110, a sensor 120, a microcontroller 130, an alarm unit 140, and a test switch 150 (eg, a test button).

[0028] exist figure 1 Among them, the power source 110 generally includes a battery, and may also include a power switch P. The power switch P can be, for example, an independent switch button designed on the surface of the detector. The power switch P can also be a device linked with the clamping mechanism designed at the bottom of the detector. When the detector 100 is installed on a fixed base, the clamping mechanical mechanism clamps the detector on the ...

Abstract

The invention provides a fire behavior detector and a timing method thereof. Through the method, a detector clock is set by adding different operations to a test switch of the detector. The method comprises that whether the test switch is triggered in a first preset period after a power switch is switched on is detected; and if the test switch is triggered, a timer in the detector is started, wherein the timer is used for timing so that the detector provides non-urgent alarm only in a prescribed period.

Description

technical field [0001] The present invention generally relates to a fire detector, in particular to a fire detector with timing function. Background technique [0002] A traditional fire detector (Fire detector) can usually provide two types of alarms, one is an emergency alarm such as a fire detected, and the other is a non-emergency alarm such as low battery power or a sensor failure. The non-emergency alarm is only to remind the user to replace the battery, related components or perform necessary maintenance in time. Moreover, traditional fire detectors do not have any restrictions on the time for non-emergency alarms. This is because traditional fire detectors are usually installed in places such as office buildings and shopping centers that are almost unoccupied at night, so even if some non-emergency alarms occur at night, they will not bring negative effects. [0003] In recent years, household fire detectors have gradually entered the market, and most of them are i...
