Cellular base station(BSS) alarm system

Recent years, the base stations for GSM Cellular networks are increasing, as well as the expanding of the GSM Network, but the GSM Cellular base station Subsystems(BBS) are always located in remote area, without security guards, so there are thieves want to steal the equipment in base station. The thieves often steal the cables, air conditioner, transformer, even the accumulator…etc.

Due to these base station far away from downtown area, without security guards, When the based station are broken in, and equipment broken done, the maintenance staff can’t get these information real time. For solving this problem, Our company designed the  GSM800-16 wireless GSM base station alarm system.

Base Station Subsystem


1. Introduction:

VS-GSM816-16 is used in base station for anti-burglary, fire detection, temperature detection, equipment detection, real time monitoring, send the alarm information sent to Monitoring Center Station (software) via SMS, as well as auto dialing adapter the GSM Network.

When the alarm center received the alarm information, the security staff can know the exact alarm information via Monitoring Center Station ( Software ).

From the alarm is triggered to receive the alarm information, it only takes 30 seconds, so that the security staff can take action in short time.
VSTAR GSM816-16 GSM Base Station Alarm System without the limitation on transmission, The Monitoring Center Station ( software ) can totally work with maximum 65000 sets of Alarm Systems.

2. Main Features:

1. Alarm data transmission via GSM Cellular Network or PSTN.
2. Can work with Active Infrared Beams or Fence Detector, Wireless/Wired PIR Motion Detector…etc anti-burglary detectors.
3. Can work with Vibration Detector for detection of the movement of equipment (air conditioner)
4. The system can detect the AC power, when the base station lose the power (theft cut the power cables), the system will trigger alarm, send SMS.
5. Can work with Smoke detector to detect the fire.
6. Can work with Temperature detector, when the temperature of equipment is higher the setted temperature, the alarm will be triggered, the system will send SMS.
7. When the alarm is triggered, the alarm system can send SMS to security staff’s mobilephone.
8. The security staff can dial the alarm system to monitoring the base station real time.
9. When the alarm is triggered, the system will send SMS to Monitoring Center Station, The Monitoring Center Station will receive the information includes Base Station Name, Address, Contact person, Telephone number, Alarm type s( anti-burglary, fire, power), Time…ect.

Security Alarm System For Base Station Subsystem (BBS)

Door/Window Magnetic Contact: Magnetic contacts are the most common sensing devices for sensing opening and closing of doors and windows. They are cheap and reliable.
Such sensors consist of two parts - A  contact that is installed on the door / window frame and an Activating magnet that is mounted on the door. The magnetic  is held in no-alarm contact position when door / window is kept closed. These are installed on a door or window in such a way that opening the door or window causes the magnet to move away from the contact switch which activates the alarm. They have proved to be a tried and tested method of monitoring any of the operable openings in the houses / apartments. These contacts are available in variety of finishes & materials. Heavy duty versions are also available for heavy doors, shutters and gates. The magnetic switches normally have both 'Normally open' & 'Normally Closed' contacts for easier integration with existing systems.

PIR Motion Detectors: Passive Infrared (PIR) Motion Sensors protect space by 'looking' for changes in infrared (heat) energy levels caused by movement of an intruder. The passive infrared detectors are passive devices. i.e., they do not transmit any form of energy. When a person enters and moves within the detecting zone, his body which is at its normal temperature of 98.6 degree F., radiates more (or less) thermal energy than the surroundings and such minute difference in thermal energy is detected by the PIR. In simple words, PIR keeps a picture of the heat levels in its view and keeps on comparing the new view with the stored one. In case there is any change then they activate the alarm.

Vibration Detector: Vibration detector is for detection of any vibration on the protected objects. For example: Put the vibration detector on the Air Conditioner, when intruder try to move the Air Conditioner, the vibration detector will be triggered.
This vibration detector with high accuracy & sensitive is adjustable.

Strobe Siren:
Typically we call it bells, when alarm is triggered, the alarm panel will switch on the siren or strobe siren,  the siren or storbe siren will make noise and strobe lights (warning sounds & lights) to alert people or your neighbours,  also it will make the intruder stop the illegal intrusions.


5. Notice:

1. The installation location must with the GSM Cellular Signal ( covered with GSM Network)  or with PSTN line.

2. Check the valid of SIM Card in the alarm system. if the SIM card without money, it can’t send SMS.

3. Regularly check the status of detectors (sensors)
