Abstract: A portable wireless alarm system includes at least two alarm devices each of which includes a signal generator for generating an action signal, wherein the alarm devices are communicatively networked with each other by means of radio frequency to contribute a security network in such a manner that, within the security network, when one of the alarm devices is triggered to generate the action signal, another alarm device is automatically triggered by the action signal to produce alert signal, so as to enlarge a coverage area of the alarm device. In addition, the alarm device is a portable wireless alarm device that is communicated with an alarm activator by means of radio frequency signal to remotely control the alarm device to be activated. Therefore, the portable wireless alarm device is capable of wirelessly setting up at a designated location with free installation to ensure the best security.

Abstract: An auto-controller is adapted for incorporating with a battery charger to charge a battery by using a thermo-control and current balance technology for extending a service life span of the battery while being cost effective. The auto-controller includes a resistor having a predetermined resistance for electrically connecting to the battery charger wherein the resistor generates heat when a predetermined current flows through that defines a reference temperature for the battery charger, and a thermo sensor operatively positioned adjacent to the resistor for detecting the reference temperature and selectively switching the battery charger on and off, whereby when the reference temperature is above a control temperature preset in the thermo sensor, the battery charger is switched off to not function and when the reference temperature is below the control temperature, the battery charger is maintained in a switch-on condition to continuously charge a battery.

Abstract: An auxiliary alert process and system thereof for alarm system are adapted for monitoring all the devices, so that a great amount of installation fee and equipment cost can thus be saved, wherein the auxiliary alert process which includes the following steps. (1) Maintain at least a sensor installed at an entrance or an exit of an existing alarm system in functioning condition when the alarm system is disarmed. (2) Monitoring the entrance/exit by the sensor to determine whether there is a motion occurred at the monitoring entrance/exit. (3) Send a detected signal to a security control device which is connected between a control panel and the sensor of the alarm system when the sensor detects the intruding motion occurred at the monitoring entrance/exit, and trigger at least a local warning device by the security control device to generate an alert signal. (4) Stop the alert signal when the intruding motion ceases or terminates.

Abstract: An action control process of a security alarm system is to render the general security alarm system to contain an auxiliary function of monitoring or detecting human activity within the monitoring area of the security alarm system, by utilizing the plurality of selected security devices selected from the security devices of the security alarm system during both armed or disarmed condition, without scarifying the original alarm protection functions.

Abstract: An additional logic algorithm is employed in the process for reducing motion-type false alarm of security alarm system automatically or manually, wherein the preset time period of the delaying period of the verification condition is reduced to a shorter first adjusted time period when a second alarm trigger is occurred after the first alarm trigger during the preset time period. If a third alarm trigger is occurred during the first adjusted time period, the delaying period is further reduced to a second adjusted time period shorter than the first adjusted time period. The delaying period will be further reduced when subsequent alarm trigger occurred. However, if there is no third alarm trigger occurred during the first adjusted time period, or there is no subsequent alarm trigger occurred after the last alarm trigger during the latest reduced adjusted time period, the delaying period will be reset to the preset time period.

Abstract: In order to enhance the process of reducing motion-type false alarm of security alarm system, a multiple time-setting adjustment control is employed in the process of reducing motion-type false alarm of security alarm system automatically or manually, wherein a cross zone delaying period during the verification condition for a second detecting signal from another motion sensor is set to have a longer time period than a single zone delaying period during the verification condition for a second detecting signal from the same motion sensor, so as to further effectively reduce the motion-type false alarm possibility without reducing the protection performance of the security alarm system.

Abstract: A backup arrangement for alarm system includes an electronic switch circuit, a DC power source, a build-in electronic Hi-sounder, and a chargeable resistor. The electronic switch circuit, which is a IC control system, has a power input connected to an auxiliary power output of a control panel of a burglary alarm system installed in house or vehicle, and an alarm input connected to an alarm output of the control panel. The electronic switch circuit further includes a normally opened switch and a normally closed switch. The normally closed switch is coupled in series with the alarm output of the control panel and the input of the build-in electronic Hi-sounder. The DC power source has an output connected in series with the normally opened switch and the input of the build-in electronic Hi-sounder. An alert output is connected to a system warning device of the burglary alarm system.

Abstract: A process for reducing motion-type false alarm of security alarm system includes the steps of merely activating the local warning system to produce local audio and/or video warning signals when any one of the motion sensors detects a motion everytime within the respective motion detecting area; delaying to activate the control panel as well as the phone dialing system which is built in the control panel for a predetermined period of time, wherein the security alarm system is in a verification condition; activating the control panel to normally respond by activating the local warning system and the built-in phone dialing system to transmit digital signals to a central station for dispatching to a designated police resource when at least one more detecting signal is sent from any one of the pre-designated motion sensors that detects another motion within the respective motion detecting area during within the predetermined period of time; and resetting the security alarm system to the original standby condition

Abstract: An auxiliary control device for a security alarm system installed in a commercial facility includes a control circuit for bypassing the electrical connection between the alarm control panel and the security devices of the security alarm system during business hour and automatically setting the security alarm system to a standby condition at the close time of the commercial facility. At that standby condition, the auxiliary control device activates the door lock control to lock the entrance or exit door but the electrical connection between the alarm control panel and some of the security devices still remains bypassing to deactivate the alarm buzzer when any human activity of the customers inside the commercial facility is detected by the motion detectors of the security alarm system. Moreover, when a leaving customer is detected by a door sensor of the exit door, the auxiliary control device will activate the door lock control to unlock the exit door for a predetermined period of time automatically.

Abstract: The present invention provides an auxiliary backup device of burglary alarm system, connected with an alarm output and an auxiliary power output of a burglary control panel and an alarm device, comprises in combination an electrical circuit having a relay means and a DC power source.
