How is sensor important for smart home

Sensing technology is important for smart home system. With sensors, the environment change can be sensed and reported to controller for analysis, the controller then commands the device adjusting and responding. The smart home system is the real automatic running smart system.

How is sensor important for smart home. How does the sensing technology change and improve the smart home system functions? Below we will analyze it.

1. Sensors provide abundant data and enable artificial intelligence of smart home system

With sensors, the smart home system will be more programmable. Home is more visible and environment change is quantized and smart home system can automatically running according to change of reality. Everything can be a virtual device and is connected. Everything is intelligent and can learn and respond. So, the smart home system can provide suitable service automatically.

2. Sensor is connection of house appliance

With sensors, the house appliance such as lighting, curtain, air conditioner, cooker can be set according to the model. So, the home is smart.

3. Only with sensing technology, the smart functions can be realized

Smart home system is based on home, with building management, network communication, house appliance automation controlling and comfort functions.

Only with sensing technology, the home model can be set and remote controlled.

4. With sensing technology, no need manual operation

The smart home system can automatically respond to environment without manual operation or input. Various sensors can work together and largely improve smart home intelligence.

5. Sensing technology is needed for products digital

The improvement of smart home system relies on digital products. Sensors adding is the way to improve the products to digital products. So, the products information can be connected, transformed, saved, judged, analyzed and executed.

6. The sensors function can be expanded with application of smart home system

The sensors can be with multiple functions when it is used for smart home system. For example, infrared detector PIR, when it is used for burglar alarm system, it is a motion sensor only to trigger alarm. But when it is used for smart home system, it can be used as motion sensor when the system armed; it can be used as sensor light when the system is disarmed. With multiple sensors and adding logical analysis, it can be used as elders monitor alarm sensor.

FAS design notice

Fire alarm system (FAS) design is standard and coded for execution. The initial design is the same by default. But there are some important notice to take attention on the design phrase. Many posts suggest and imply how to design fire alarm systems for people starting out fire alarm system design. According to the fire alarm system project requirement, the specific details and codes of fire alarm design may be varied. But remember fire alarm system is a system detecting problems and notifying people with sound and light. So, both detection system and notifying system should work effectively.

Notice 1: About wiring circuit of FAS: there are two type wiring circuit: T circuit and ring circuit. We suggest to use ring circuit. If one detector is fault, it can be easy inspected with ring circuit and hard to inspect with T circuit. Ring circuit is more reliable than T circuit for the whole system. If circuit is cut, ring circuit system can be found with fault and T circuit may be not.

Notice 2: About stairway fire emergency broadcast. Stairwell is an independent detection area and stairway fire emergency broadcast is an independent notify area as well. The design is to improve and ensure the system security and reliability.

Notice 3: Setting up short circuit isolator. Short circuit isolator is needed for the FAS. Generally one short circuit isolator is needed for every 15 elements and not a detection circuit. That can raise the FAS reliability.

Notice 4: Every element should be numbered on the system construction drawing. It helps management of every department.

Notice 5: If the detector is installed in hidden place, such as the ceiling under the floor, then the independent indicator is needed for notification of its working status.

Notice 6: Using with sounder detector in bedroom to notify people in sleep. The public area audio video notification device may be not loud enough to wake up sleep people in bedroom, so, detector with sounder is needed.

2. The alarm system does not alarm after system armed or forced armed and wireless detector is triggered, why?

Possible causes: The detector battery voltage is low. The detector is not correctly learned to the alarm control panel. The detector is not programmed into the alarm system zone or zone attribute is not programmed correctly. The distance between wireless detector and alarm control panel exceeds rated distance. There is metal block between wireless detector and alarm control panel.
Solutions: Change the battery and re-enroll the wireless detector to the alarm control panel, correctly programming the detector zone attribute. Shorten distance between wireless detector and alarm control panel. If there is metal block, please replace the wireless detector.
3. The alarm control panel can not receive remote signal and transferring signal, why?

Possible causes: Power supply is not enough for remote controller or signal transceiver, the wireless remote or transceiver is not enrolled correctly into the alarm control panel. The distance between the remote or transceiver and the alarm control panel is too long. Alarm control panel can not decode the received signal.
Solutions: Change remote battery and re-enroll the remote controller to the alarm control panel correctly. Shorten the distance between the remote control or the transceiver to the alarm control panel. If above solution does not work, there maybe problem of the wireless receive module of the alarm control panel and it should be return to factory for repair.
4. The alarm control panel makes false alarm, why?
Possible causes: the detector fault or wrong installed.

Solution:
Check which zone triggers alarm and check the detector.
5. The alarm control panel makes sounds at normal work status.

Possible causes: The alarm control panel can make sounds of alarm, fault alert, delay arm sound, alarm delay sound etc.
Solution: Check and identify which sound the alarm control panel made then solve the problem according to the sound. If no alarm is triggered by detector and no instruction is made to the alarm control panel and it makes sound, then there maybe the alarm system error.
6. External siren is wired to the alarm control panel, but it does not sound when alarm control panel alarms.
Possible cause: the Positive and negative wiring between siren and control panel is reverse or short-circuit. The siren voltage is low (less than 12V). The external siren is not programmed or correctly programmed to the alarm system.
Solutions: Check and confirm the wiring is correct. Check and confirm there is 12V voltage output to the siren when the system alarms. If not, please program the system and turn on the external siren. If all above is ok but still no output from the external siren, please change a siren to test or change a alarm panel to test.
7. The alarm control panel does not dial alarm receiving number when it alarms.
Possible causes: strong interference or short-circuit, cut of the telephone line. The receive phone number and communicate format, communicate grade is not programmed correctly to the alarm system. The telephone theft function is turned on.
Solutions: Check and confirm the telephone line is good without strong interference, short-circuit and cut. If additional code is needed for outline dialing, please add it to the receive phone number when program it.
8. The alarm control panel does not dial CMS telephone number when it alarms
Possible causes: strong interference or short-circuit, cut of the telephone line. CMS telephone number is not correctly programmed into the alarm system or user code is not enrolled or not correctly enrolled.
Solution: Check and confirm the telephone line is good without short-circuit and cut. Check and confirm the CMS number including communicate format and grade and user code is programmed correctly. If all above is good and problem still exist, then please check the interference of the telephone line. CMS communication is data communicate and strong interference may lead to communication interruption.

Conclusion: the updated new technology alarm control panel has voice, LCD menu, graphic prompt and low battery alert. So, alarm system troubleshooting is easy and the system has self-check maintenance program. So, alarm system is not coded and easy to operate than before.
