Police sound system (note: self-test only checks the internal functions of the detector itself, and there are some issues during self-test)RS485Signal output). Work: Under normal circumstances,The detector is approximately every 6 The second indicator light will flash once. The detector automatically detects the smoke concentration in the surrounding environment,And automatically compensate for sensitivity based on the usage environment conditions. When the smoke concentration approaches the alarm value, the detector accelerates the intelligent calculation of the smoke concentration trend,At the same time, the alarm indicator light starts flashing. If the calculation result reaches or exceeds the alarm value,The detector begins to sound and light an alarm. When the smoke concentration in the surrounding environment drops below the alarm value,The detector automatically returns to normal working condition. When the on-site temperature of the detector reaches 57 After the temperature drops, the detector indicator light starts flashing when the temperature on site is below57The synchronous detector automatically returns to normal working condition.RS-485Communication: Adopting standardsRS-485Communication interface, communication baud rate can be selected as:2400bpsThe4800bpsThe9600bpsThe19200bps, default to4800bps.Modbus-RTUProtocol: The address of the alarm status register is 03Is it using functionality 03Read, status is“0”Or“1”, often open（“1”To be normal“0”For alarm purposes, normally closed（“0”To be normal, “1”For alarm purposes.
