It is that DC9V or AC220V change DC9V that the embodiment alerting signal is sent the device power supply, it is that DC3V or AC220V change DC3V that alerting signal receives the autodialer power supply, warning percent of call completed＞98%, the mistake of reporting to the police is sent out rate＜1%, the identification time delay time 15S that reports to the police, radio pager or telephone set send the response speed of warning＜30S/ time, repeat the time interval＞45S of dialing alarm, alerting signal generator and alerting signal receive wireless transmission coverage＜100m between the phone dialer, the transmission frequency 100MHZ of alerting signal ± 5MHZ, alerting signal transmitted power＜10mw, the alerting signal generator shell is of a size of 115 * 65 * 40mm, it is 155 * 84 * 40mm that alerting signal receives the phone dialer shell sizes.
BB plane No. sign indicating number form is 1270 * * * * eight, available 22 at most of assigned telephone numbers.
The utility model compared with prior art has the following advantages:
The first, this detectors is various, only needs the corresponding sensor of transposing can realize that the multiple preventions such as antitheft, fire prevention, gas leakage preventing, protection against the tide report to the police, simultaneously can also be by being connected to the K switch before the dialing alarm controller 81The sound warning receiver of common frequency modulation that is selected to carry use.
The second, this alarm equipment alarm reliability height.At first, alarm designs has been considered anti-false alarm time delay structure, only when abnormal conditions continue to occur, just understands outside dialing alarm.Secondly, alarm can be realized repeating dialing alarm, disappears up to abnormal conditions; Secondly, dialing alarm does not have any sound, can not startle the criminal again.
Three, this alarm is realized the unmanned warning.When on-site supervision is stolen, fire, gas leak, during abnormal occurrencies such as water inlet, alarm by with local call or radio call networking, make operator on duty receive alerting signal away from on-site supervision.
Four, adopt frequency modulation wireless receiving and dispatching mode to be connected between the alerting signal generator of this alarm and the alerting signal receiver, thereby volume is less, it is hidden to install, conveniently moving, coverage can reach 100m.
