RS485 smoke detector, high and low temperature resistant photoelectric smoke detector

Description :

　　Product Overview

　　This product is a photoelectric smoke detector that works based on the principle of sensing smoke particles. Adopting unique structural design and optoelectronic signal processing technology, it has functions such as dust prevention, insect prevention, and resistance to external light interference, ensuring the stability of the product from a design perspective. This product has a good response to visible smoke generated by slow smoldering or bright burning. Suitable for smoke monitoring in indoor environments such as residential buildings, shopping malls, hotels, and warehouses.

　　Features

　　This detector is non coding type and can be directly connected to a DC power supply during operation. During normal operation, the work indicator light flashes. When an alarm is triggered, the alarm indicator light is on. The detector has a pair of output contacts, which close/open after an alarm. Power off/automatic reset is required after smoke-free operation. The detector is installed on a positioning base.

　　● Power off/automatic reset optional

　　● Infrared photoelectric sensor

　　● Intelligent logic control, filtering out various false alarms ● Normally open/closed (NO/NC) alarm output ● Networked output/LED indicator alarm ● SMT process manufacturing, strong stability

　　Dustproof, insect proof, and anti white light interference design

　　Metal shielding cover, resistant to radio frequency interference (20V/m~1GHz)

　　Product Installation

　　● Choose a suitable installation location, usually installed in the detector coverage area

　　On the central ceiling.

　　● Peel off the small buckle on the base and use the jump cap to select according to the instructions on the board

　　Select the corresponding reset mode and alarm output mode of the detector.

　　Connect the power line and signal line to the installation base plate (installation base plate "1" is for electricity)

　　Source level; 2 "is the negative pole of the power supply; three485B for 4, 485A for 4.

　　Fix the installation base plate to the ceiling with screws.

　　Align the positioning protrusion at the bottom of the detector with the positioning groove on the installation base

　　Rotate clockwise to install the detector.

　　Parameter Settings

　　1. Select the correct COM port (check the COM port in "My Computer - Properties - Device Manager - Ports").

　　2. Connect only one device separately and power it on. Click on the software's test baud rate, and the software will test the current device's baud rate and address. The default baud rate is 4800bit/s and the default address is 0x01.

　　3. Modify the address and baud rate according to usage needs, and also query the current functional status of the device.

　　4. If the test is unsuccessful, please recheck the device wiring and 485 driver installation.
