Evaluation for JTY-GD-802 Standalone Smoke Detector

This paper introduces the JTY-GD-802 type independent type smoke detectorevaluation. Independent type smoke detector is usually installed in the home, Internet cafes, detection of small places smoke shops are not suitable for wiring installed firealarm system. Independent type smoke detector by 9V battery or power supply directly, without and fire alarm controller connection, convenient installation and use,can realize the independent detection, independent alarm. With the trend of home fireis more and more high, governments at all levels will also be independent typedetector setup written into the local norms. But the independent type detectors usenow the domestic market on the quality and function of how real?

The convoy letter Shenzhen City Safety Technology Co., JTY-GD-802 independenttype smoke detector test. The test parameters are as follows:

The basic properties of diameter 105, 105 (base) 135g weight (including battery) shell material ABS mounting hole distance 60mm use environment temperature -10 ℃ - +55 ℃, relative humidity below 95, no 80 μ A alarm current 5.9mA alarm time 20.4s alarm sound 76dB condensation function parameters working voltage DC 9V monitor curren

Product certification.

JTY-GD-802 independent type smoke detector is independent of Shenzhen Kai Weiletter security technology limited production of smoke fire detector, the product isexported to Europe, in line with the EU 14604 standard, has passed the European CE certification, in the country has done to fire detection products, but don´t do 3Ccertification. The detector using a 9V laminated battery power, the battery is generallya year and a half time to replace a. To use the ABS material products, impact resistance, heat resistance, low temperature resistance and excellent electrical properties. Detector diameter 105mm 95mm, shell is a white porcelain

.

Exterior and interior structure:

Open the JTY-GD-802 independent type smoke detector housings can be seen, the structure design more reasonable internal detector, detector with no screw fixed way,very convenient disassembly, greatly facilitate the detectors used in maintenance andcleaning.

Working current:

The JTY-GD-802 independent type smoke detector installed in the test board, and placed in a certain height, the independent type smoke detector function test we don´tthe detector current, alarm time, the alarm sound parameters measurement. Current detector static is 80 μ A, alarm current 5.9mA, low power consumption in similar products, for use in battery powered detector, can extend the battery life

Alarm sound:

In the use of pipe of JTY-GD-802 independent type smoke detector fire alarm test, the detector can respond within 20.4 seconds. Maximum alarm sound can reach 78.1dBdetector (3 meters away from the detector at the right), the sound pressure level and compared to similar products or slightly inferior to the point, the alarm sounds similardetectors in general will reach more than 85dB.

The detector also has under electric alarm function in the battery is used up, when the battery voltage is lower than 7.5V, the detector will also be issued a "tick" sound and light indicator, a buzzer for about 40 seconds and the time, thus remind maintenance personnel to replace the new battery, this function in similar products is not.

The local government is attaching more and more importance to small civil occasionsand fire detection settings, independent type smoke detector use will have a quantum leap, the "quality" in the end how? We will also continue to pay attention.
