Please make sure the Control panel is regularly serviced at least once a year by your installer.NAMECOMPANYINSTALLATION DATETELEPHONEFAXMOBILEOTHER INFORMATION1:0 SETTING THE SYSTEMTo arm the system enter your user code. The exit tone from any extension speakers will sound at a low level, the keypad buzzer will also sound. Any pulsed tones should return to a continuous tone once you have left the building and the sensors have cleared. The control panel arms after the exit timer has run out, at this point the tone should cease. If for any reason the tone does not go continuous after all the sensors have cleared, return to the keypad and press the # key to abort the setting procedure. If the internal sounder activates after the timer has expired, return to the keypad and enter your user code and press #. Now refer to fault clearing. (section 14:0)1:1 Selecting Full SetEnter user code, no further action is required, leave the premises by the authorised exit route.1:2 Selecting Night SetEnter user code then press * then 0. The zones pre-programmed to be isolated will start to flash. The extension speaker sounds can be removed by the installer, if this is the case the extension sounder may stop as soon as night set is selected. If the installer has programmed instant night set the system arms as soon as the selection is made.1:3 HOME SETEnter user code then press * then 8. This isolates any zones programmed for isolation. Please note that this setting method will allow the isolation of ALL entry routes including zone 1 (if enabled by the installer). Follow the paragraph 1:0 for guidance regarding exit tones etc.2:0. MANUAL ISOLATION OF ALARM ZONES .There may be occasions when you need to isolate additional zones. Arm the system as above, then press * then the zone number you want to isolate. That zone will flash indicating a successful isolation, if you want more zones isolated press * and another zone. If any zone is barred from isolation an error tone will be emitted.Zones that cannot be isolated• Fire• PA• Tamper• Zone 1 in Full Set• Zone 83:0 DISARMING THE SYSTEMEnter the protected area by the authorised entry route, a single continuous tone will be heard from any extension speaker and from keypads. Proceed directly to the keypad and enter your user code, the system will disarm. If the entry tone from the speaker changes to rapid pips then you have less than 10 seconds to disarm the system.4:0 DISARMING AFTER AN ALARM4:0:1 AFTER THE PANEL HAS AUTO RESETEnter the protected area by the authorised entry route, an intermittent tone will be heard from any extension speaker, proceed directly to keypad and enter your user code, the system will disarm, the zone/s will light on the control panel to indicate the cause of the alarm, refer to panel reset section 13:0 to clear the panel.The first to alarm will show a constantly illuminated light.Subsequent alarms are shown as fast flashing lights.Zones that were isolated are shown as slow flashing lights.4:0:2 WHILE PANEL IS IN ALARMGo directly to the keypad and insert your user code, the system will disarm, the zone/s will light on the control panel to indicate thecause of the alarm, refer to panel reset to clear.(section12:0)The lights follow the same descriptions as above in section 4:0:1. 5:0 TAMPER FAULTSThe control panel is equipped with a common tamper circuit giving protection from unauthorised handling. If the tamper circuit is broken during any unset period the internal sounder will trigger and the tamper light will illuminate. Proceed directly to the keypad and enter your user code, the internal sounder will stop and revert to a low two tone sound. Press the # key the panel will reset, if the tamper light continues to flash then the cause of the tamper condition is still present. Refer to fault clearing.(section 13:0)6:0 PERSONAL ATTACKIf your system has a personal attack button fitted this will be linked into the alarm system as a 24hr device. This means the PA button will be live all the time. If the PA is pressed all the sounders will operate and bring up the zone light programmed as PA. Proceed directly to the keypad and enter your user code, the sounders will stop and revert to a low two tone sound. Press the # key the panel will reset, if the zone light continues to flash then the cause for the personal attack condition is still present. Go to the personal attack button(s) and reset with the special key provided, the zone light should go out. If the light continues to flash refer to fault clearing. (section 14:0)Note: If the panel is armed and a PA is activated, you will need to disarm the system as explained in section 46:0:1 PERSONAL ATTACK FROM REMOTE KEYPADIf the installer has programmed personal attack on the keypads, pressing and holding the * & # keys together for 3 seconds activates the system as in 6:0. The only difference is that the tamper light will illuminate. Enter the user code, the sounders will stop and revert to a low two tone sound. Press the # key and the panel will reset.7:0 FIREThe installer may have linked smoke detectors to the control panel. If so the sounder will give a loud whooping sound and the external sounder will pulse at 2 second intervals. When the panel is set, the external sounder constantly sounds. Make sure that every one exits the premises. When you are sure that it is safe to return back, proceed directly to keypad enter the user code. The sounders will stop and revert to a low two tone sound. Press the # key the panel will reset.8:0 CODE CHANGEThere maybe times that you need to change your user code. The system has 2 user codes. To help you remember your new code, write it down before changing it and after you have successfully changed and memorised the code destroy the written code. Remember, try not to use obvious codes such as the current year. To change user code 1 enter your existing user 1 code then press *, then 9 then 1. Four lights will illuminate, enter your new 4 digit code. For every digit pressed of your new code, one light will extinguish. Once your new code is entered the panel will give you an accept tone, if the panel does not accept your code then you may be in conflict with user code 2 or the engineering code, the panel will abort the code change and retain your old code. Try again with a different code. Check your new code is functioning correctly by performing a full or night set then abort by pressing #.To change user 2 code go through the above procedure but press *, then 9 then 2.Panel Default Code is 1,2,3,4 for user 1 code. User 2 code is disabled by default.User code access levels.• User 1 code can alter both user codes.• User 1 code can disable user 2 code. (To disable user 2 code changed user 2 code to 0000)• User 2 code has the same setting rights as the user 1 code• User 2 code cannot alter the user 1 codeIf for any reason you loose your code or mistype in a code when changing it, the installer will need to be contacted to default the panel codes.9:0 SOUNDER TESTSIt is advisable to check that the sounders are working correctly periodically.To do this go to a keypad, enter a user code then press * then 9, each of the tests lasts for 5 seconds. All the lights on the control panel will illuminate, and the system tests start. The lights will go out and the internal sounder will activate (proceed outside where the external sounder is fitted). The external sounder will trigger then the external strobe will flash (if fitted and enabled) and then the panel will clear down. The test is now complete.10:0 WALK TESTINGIt is advisable to check that the detection devices are communicating with the panel. This kind of testing should be performed every 3 months. To do this go to the keypad enter a user code, then press *, then 9 and 4. When any detector is activated or a door fitted with a contact is opened, the internal sounder will give a loud pulsing tone and the zone light will illuminate. Clear the detector or close the door and the sound will revert back to a continuous sound, proceed to the next device until you have completed testing all the zones.NOTE: The zone LED’s will stay on at the keypad until the tests have beencompleted to allow confirmation that all zones have operatedcorrectly.press * to exit the walk test mode.11:0. CHIME.The control panel offers the ability to have chime on a zone when unset.This feature will emit a chime tone via the extension speaker whenever a zone is activated. To achieve this press the * key and the number key that represents the zone(s) you want on chime. The light for the zone willilluminate. Press * to accept the zones on chime. To remove a zone onchime press the * key and the zones will light up that are currently active.Press the key that represents the zone, the light will go out, chime is now disabled on that zone.

sim800l模块用法
sim800l模块用法一、引言Sim800L模块是一种用于无线通信的硬件设备,广泛应用于物联网、远程监控、智能家居等领域。
本文将介绍Sim800L模块的用法,包括模块的基本连接方法、通信协议及常见问题解决方法。
二、硬件连接1. 供电连接:将模块的VCC引脚连接至3.7V至4.2V的直流电源,GND引脚连接至电源的地线。
2. 串口连接:将模块的TX引脚连接至控制器的RX引脚,RX引脚连接至控制器的TX引脚。
同时,将两者的地线连接。
3. SIM卡连接:将SIM卡插入模块的卡槽中,确保插卡方向正确。
若需使用GPRS功能,还需向运营商申请相关服务。
4. 天线连接:将模块的ANT引脚连接至天线,确保连接牢固有效。
三、通信协议1. AT指令:Sim800L模块通过AT指令与控制器进行通信。
常见的AT指令包括AT+CSQ(查询信号强度)、AT+CMGF(设置短信格式)、AT+CMGS(发送短信)等。
2. 串口通信:利用串口连接模块与控制器,通过发送特定的串口指令来实现功能。
控制器需配置相应的串口通信参数,如波特率、数据位、停止位等。
3. TCP/IP通信:Sim800L模块支持TCP/IP协议,可实现与服务器的网络通信。
通过建立TCP连接,可以实现数据的传输和接收,适用于远程监控、数据采集等场景。
4. HTTP通信:Sim800L模块还支持HTTP协议,可以通过HTTP GET或POST请求发送数据,实现与云服务器的交互。
通过HTTP通信,可以实现物联网应用的数据上报、远程控制等功能。
四、常见问题解决方法1. 通信异常:如果无法正常与控制器通信,首先检查串口连接是否正确,确保引脚连接牢固。
同时,检查控制器的串口通信参数是否与模块设置一致。
2. 无法上网:若无法实现GPRS上网功能,可先检查SIM卡是否插卡正确,运营商的GPRS服务是否开通。
同时,可尝试重启模块或更新模块固件版本。
3. 信号弱:如果信号强度较弱,可尝试将模块远离干扰源,或更换合适天线以增强信号接收效果。
sim800sim800a用户手册
SIM800/SIM800A模块用户手册Tzw-SIM800/SIM800A模块开发板是一款高性能高性价比工业级的GSM/GPRS 模块(开发板)。
本模块采用SIMCOM公司的工业级SIM800/SIM800A 芯片, 可以低功耗实现语音、SMS、数据和传真信息的传输。
注:SIM800支持4频,通俗讲就是可以全球使用,SIM800A支持双频,大陆使用。
1.1 主要参数模块支持TTL接口控制,可以方便的使用电脑或者单片机控制实现GSM/GPRS 功能。
TTL电平支持3.3v/5v系统。
模块DC接口外部输入工作电压 DC5-15v(能保证给SIM800提供 2A 电流(注1),因为兼容5V,所以可以用USB转TTL或者5V单片机系统直接供电(很多同行不行)。
注1:这里指的2A 是指经过模块板载DC-DC 变换后的4v电压,供给SIM800模块用的电流,不是指外部输入电源一定要2A,外部电压越高,需要的电流就越小。
比如12V 1A 的电源,按90%的效率计算,可以提供2.7A@4V 的电流,所以用12V 1A 的电源给YIXIN_SIM800模块供电是已经足够的。
综上所诉,使用DC9V以上使用1A的电源已经足够,如果使用DC9V以下电压的电源,请至少选择2A的电流参数。
这里讲的1A都是足A的,不能是劣质电源(劣质电源写的1A可能实际500mA都没),若电源不能保证质量很好足A,可以选择电流大一点的电源。
1.2 模块的接口介绍注2:VIN为模块的供电电压(如单片机/PC TXD RXD端口高电平是5V,可以直接用跳线帽与VMCU短接)宽电压供电:5~15V DC电源供电,灵活适应不同供电电压的系统,一般我们建议用5V。
VMCU为TXD RXD的端口高电平电压(单片机/PC T XD RXD端口高电平是5V的就接5V,是3.3V的就接3.3V)。
SIM卡座为小卡座,支持移动、联通,不支持电信。
2.1 PC调试按模块上的示意图插好卡后,我们选择用USB转TTL给模块做电脑调试。

湖南电信L800交付技术规范书v120211103
湖南电信L800交付技术规范书v1202111031 概述L800不管是覆盖农村、还是覆盖城区,其要紧工作内容均可分为两部分:CDMA重耕及优化、L800工程交付及优化,本文要紧对这两部分内容进行描述。
2 L800交付全景图Figure 1 L800交付全景图3 L800M部署特点及原则3.1 L800M农村部署特点◆剩余频率多,建设L800对CDMA影响小:利用现有频率资源,不动CDMA频率,使用夹心方案,快速完成部署◆连续覆盖是关键:LTE在农村无覆盖,电信也没有除CDMA外的站址资源,因此,直接全部利旧CDMA站址,1:1的建设LTE800M3.2 L800M进城部署特点◆无剩余频率资源,建设L800必将影响CDMA:不管使用靠边方案或者是夹心方案,都涉及频率调整或者翻频,都会影响CDMA 补充覆盖是关键:LTE在城区已有了较好覆盖,800M建设LTE无法提供较大带宽,做数据无优势,作为L1800的深度覆盖补充是最优选择。
3.3 L800交付策略3.3.1农村交付策略16年规划批复农村800M站点,原则上与C网基站1:1共址部署;有原则的增加CL站点。
设备选型:全网使用2T4R+大功率建设;天馈方案:CL独立天馈,农村塔站不增加租金;站址方案:农村覆盖受限,新增天线与CDMA 1:1叠加建设;3.3.2城区交付策略建设规模:原则上城市C网室外宏基站1:1共站重耕部署(约15万);设备选型:全网使用2T4R进行建设;天馈方案:与L1800共天线,更换天线不增加租金;站址方案:基于城区所有电信C网站址进行1:1选址;总结:城市区域推动L800M跟随L1800M建设一张OneLTE网络;农村区域推动L800M叠加新建,CL解耦;4 L800频率频点规划4.1 800M重耕方案选择城市地区800M频率使用方案要紧分为1.4M方案、3M方案与5M方案三种,我省1X使用数量均在3个及下列,要紧考虑3M方案与5M方案两种重耕的CDMA 频点78、119、160、201 78、119、160 119、160、2014.2 L800农村频率规划如下图为L800 5M带宽频率全网频段一致,都使用2452频点。
