Product Name: Photoelectric ion smoke detector CHJ-9500 Product Category: Wireless networking smoke detector (with 315M wireless transmitter) Detailed description: Features: ◆ photoelectric detection mode ◆ Ceiling installation ◆ optical maze ◆ Uses low power CMOS microprocessor ◆ special moisture-proof design ◆ independent / networking / wireless output (optional) ◆ manual test, manual reset function ◆ stable and reliable performance ◆ single-sided PCB technology ◆ ultra-thin structure design ◆ unique design, dust, pest control, anti-external light interference product information sensor Optical chamber maze Operating Voltage 9VDC / 12VDC Working current Electrostatic current less than 10ua Alarm working current 10 - 30ma Smoke sensitivity Compliance with ul217 standard test value per second 3.2% weak gray smoke detector response working environment -10 ° C to 50 ° C Alarm volume 10 feet at 85 dB Alarm Output Wired way: the scene sound and light alarm / whether the output, the alarm automatically cut off Wireless mode: Alarm transmission frequency F: 315M / 433M, Wireless transmission distance (shielding distance): 50M, can be customized Round size R = 105 mm, H = 38 mm First, the installation instructions (1) characteristics Power: 9V Hamilton battery or carbon battery Operating current: quiescent current less than 10UA, working current between 20-25UA. Smoke sensitivity: in line with UL's 217 standard. Operating temperature: 40oF-120oF (-4 ℃ -50 ℃). Gas interface temperature: 10% -90%. Buzzer volume level: 10 feet at 85 dB. Battery life: about 1 year. (2) installation The room every 25-40 square meters installed a smoke, an important device above the 0.5-2.5 meters to install smoke. Select a suitable mounting area with a screw to secure the seat, connect the smoke to the clip and connect it to the holder. Draw two holes on the ceiling or on the wall according to the holes of the mounting bracket. Drill two holes in two holes. Insert two plastic laps in the two holes, and then press the back of the mounting bracket against the wall. Insert and tighten the mounting screws until the mounting bracket is securely removed. The detector is a closed device and is not allowed to open, please put the battery into the compartment on the back of the machine. The back of the detector is attached to the mounting position and clockwise. And make sure that the two screw heads have been slipped into the waist hole. Gently press the test button to see if the detector is working properly. (3) procedures for work, testing and maintenance The detector is already in operation after it has been installed, in which the light-emitting diode flashes approximately once per minute. When the combustion particles are detected, the detector will issue a crisp loud alarm sound until the air is flattened again. (B) technical art parameters: The factory test is rated at 3.2% per foot of weak dust and the sensor reacts; Working environment: -5 ℃ -50 ℃, 10-90% non-condensing; Buzzer Volume strength: 10 feet to 85 dB. Second, the test Press the test button for at least 3 seconds, a crisp and loud pulse alarm signal will be issued. This means that the detector is really working, while the LED is flashing at the same time as the alarm. The detector can also be tested by blowing smoke into the detection chamber. (Once a week to do a test to prove the reliable work of the detector) Third, the installation and maintenance Note: ● can not be installed above the temperature, high humidity, otherwise it will affect the sensitivity; ● To keep the sensor working efficiently, every six months to clean the sensor, the first power off, and then use a soft brush to clean the dust can be, then the power to start.
