Fireproof Power Alarm System Power Failure GSM SMS Alarm

The principle of power transformer burglar alarm

     Wireless monitoring alarm mainframe installed on telegraph pole or near transformer.Power line or transformer once stolen, three-phase disconnection or power outage,  alarm host immediately detects and  send SMS and voice message to receiving host, and the host receives the alarm signal after the data is transmitted to the microcomputer, microcomputer  analyze  the alarm host and  possible fault line, after the sound alarm, alarm  screen display time, date, alarm extension, transformer fault and fault lines. The electronic map display the fault alarm and the actual location of transformer. The alarm data stored in the database for  inquiry. The leadership on duty immediately deal with relevant problems after the alarm call and send the police to do scene inspection.

Following are the specific functions:

1Can connect external industrial camera, this system with own SMS, MMS, Email functions

2 8 wired zones,open/closed alarm mode is optional by self-programming

3Fixed code: 40 wireless zones,315/433MHz(optional)

4Digital inputs are adopted optical-coupled isolators, which can prevent external high voltage from destroying internal components.

5Send SMS automatically to report the state of digital input when it returns normal status.

6Wireless keyboard for setting phone No.

7Arm/disarm remotely through GSM SMS

8Modify zone content (Chinese 70 words, English 140 letters )

9Send SMS to 5 preset mobile phone numbers while alarming

10Auto-dial 5 preset phone numbers while alarming and monitor the sound at site.

11Record function: Maximum recording time:1 min

12Voice function: support play the user record voice

13With wired Mic interface and siren interface

14Inquiry host’s status and alarm events through SMS

15Inquiry zones’ name and arm/disarm status through SMS

16Digital inputs are adopted cal-coupled isolators, which can prevent external high voltage from destroying internal.

17GSM network wireless communication for alarm, no PSTN cable, not fear cable cut

18Temper device: Arming while the control panel removing or shaking.

19Connect with alarm center through GSM network 

20With ROHS/CE/FCC certifications, conform to 3C safety standard and GB12663-2001 government standard

1.Three phase four line power off alarm

Theft usually cut wires to steal transformers, but when three phase cut or power off, monitoring host will immmediately detect and send wireless SMS message or voice message to receiving host, receiving host will transmit alarm singal  to microcomputer, then microcomputer will alarm after analysing and judging the host and find fault line through alarm software.

2.Three infrared warning

This method mainly use dual infrared and microwave to detect ane early warn.when someone is trying to close to the transformer, infrared shooting will detect the intruder, then alarm host trigger transformer burglar alarm siren to drive away intruders through high pitched voice.

3.SMS alarm

This method is to preset a center number and multi user numbers. When the transformer's security is threatened, the alarm will send message to mobile phones to alarm, duty officers receive the report immediately sent police to check situation and  deal with relevant problems.

4.Network alarm

The computers of receiving alarm center auto receive alarm,  users can clearly see the status of transformers through electronic map.

5.Vibration and pedal alarm 

When someone tries climbing the telegraph pole of transformers, after installing a pedal sensor, it will alarm when someone is climbing. When being beaten or moved, it will alarm through viberation sensor.




1. Many power transformers were stolen overnight in December ,2015 in Cangzhou Hebei Province, which caused economic loss of 200,000 RMB.

2. September 27, Mazhang District,inner copper wire stolen, worth 20,000 RMB transformer became scrap

3. Sep. 26 transformer was hollowed out in Taiyuan



Structure of power transformer burglar alarm: transformer anti-theft alarm host, GSM receiving host, alarm center software(center software and electronic map) ,siren.




Warm Tips: BL3000 has 8 wired guarding zones. It has power off GSM message and calling function,arm mode function,time arm and disarm function.You can add PIR sensor, vibration sensor, displacement sensor accoring to your needs.
