2AB4QN4Water leak host panel

GSM Water Leak Detection Device Panel Model Number: N4 Sensor Model Number: WS01 In this documentation it is a hardware description for N4 and WS01. Any people and any group do not copy this file without permission for business and technical reference. 2015-09-15 System Diagram This system provide a “Early Water Leak Warning” Service. The below is system diagram. The water leak sensor (WS01) will inspect the water leak status in zones. When get a water leak action, WS01 will send a local alarm signal to the panel (N4) over local wireless ASK433, and N4 will send a SMS to monitor center with WS01 alarm message over GSM channel. At this time the monitor center will send a mail or SMS to home owner or water security server provider.

It will get the program from flash to memory, run timer , exception, GPIO, database table initial. And set power inspection, audio channel, ASK433 module channel and GSM module. Then MCU will send some commands to GSM module for GSM network register. When network register finished, the panel enter standby mode. Standby mode In this mode the panel power consumption is lower. MCU enter standby mode and waiting for some external trigger. The trigger is the below. 1. GSM command. 2. ASK433 message. 3. Button operation. Led display N4 have a dual-color led on the front panel, different color is different means. 1. Red on: Mobile network offline 2. Red off: Mobile network online 3. Green on: Arm 4. Green off: Disarm Network Inspection In zero o’clock the panel will send a SMS to identify the mobile network status every day. Use this function to make sure the panel is no problem and give SMS center a network status reference. The SMS like the below. This below SMS means GSM network is no disconnect exception in one day. GSM / DISCONNECT / 0 TIMES Parameter Setting 1. Monitor Center number setting In this system only has one monitor center. All of SMS exchange via panel and monitor center over GSM channel. So in normal working mode the panel only storage one monitor center number in it. But for panel parameter setting a testing/setting number must join the panel firstly. Setting a testing number using any mobile phone Service Password #2# Testing Phone number The service password is the panel service password. The initial is “888888”. Example: 888888#2#13522161431, this operation set the testing number 13522161431. Setting a monitor center number using any mobile phone Service Password #1# Testing Phone number Example: 888888#2#13522161431, this operation set the monitor center number 13522161431. Clear all number using any mobile phone Service Password # Example: 888888#, this operation clear all number in the panel include testing and monitor center number. 2. Sensor setting 1) Ensure the testing number or monitor center number is saved in the panel. 2) Using the testing phone or monitor center number send a sensor zone number (1,2,3,4,5,6,7,8,9), the panel receive this number and sound No.x sensor code is starting. 3) Push the water sensor back plane button to send a code to the panel. The panel will check this code. If the code is presence, the panel sound a tick “di” to tell the customer this code is duplicated. If the code is right, the panel will sound the sensor code. 4) If customer hear the sensor code voice, push the service button and hold 3 seconds, the customer will hear a code successful voice and the sensor code will be save. 5) When sensor code status, push the service button and release it immediately to force the panel exit the sensor code status. 6) When sensor code status, every sensor code time line is 120 second. If the time is up, the panel will exit the sensor code status automatically. 7) When a sensor code is successful, the panel will wait the next sensor code automatically until sensor code exit is reactive. When code sensor number is full (No.5), and finish No.5 sensor save operation and panel give a voice” coding end”. 8) When exit the sensor code status, the panel will send a SMS message to mobile phone to identify this zone code result, like the below. The below SMS means zone 1 code five water sensors and every sensor code is in the list. Zone 1: 1.903B 2.68BA 3.3345 4.B875 5.9D34 9) In power off status push the service button and hold, when power on until hear a “welcome” voice, the whole sensor code will be deleted. 3. Password setting The panel built-in two password. One is Service password for the panel operation, another is super password for restore the service number by system administrator. If you are a system administrator, please contact the system provider for super password. Restore the service password(Only for administrator use, the default is “9795”, not change) Super Password #3# Service Password Example: 9795#3#9987, using this SMS command restore the service password 9987. Change the service number using any mobile phone. Old service Password #0# New Service Password Example: 334576#0#998702, this operation change the service password from 334576 to 998702. 4. Fix disarm When disaster on site and not fixed in …
