This article describes the three motorcycle alarm  circuit . The circuit is very useful, it is worth Duokanjibian then master the principles of the theory. This circuit has an intermittent alarm output and automatic reset. It can be manually operated with a key switch or a hidden switch; but it can also be connected to automatically set when you disconnect the ignition. By adding external relays can make a stationary bike, flashing lights. Any number of normally open switch can be used. With the "tilt" switch, move or close when the steering wheel when the bicycle is raised off the side stand or push the central station. Replace the use of protective micro switch movable plate mold protection and lid of the trunk and so on. Once activated, the siren rate switch on and off by R9 & C5. For example, increasing the value of C5 will slow down, while reducing the value that will make it faster R9. But at least one switch remains closed the alarm sounds. About thirty seconds after all of the switches has been opened, the alarm will reset. How long to turn off depending on the actual characteristics of the components used. You can adjust the time to meet your needs change value of R6 and / or C4. Circuit boards and switches must be protected elements. Moisture or condensation can cause malfunction. Components are plotted lie flat on the board - but the connection is closed or installed between adjacent tracks to walk upright. The links are bare copper wire on the component side. Support materials, including a detailed guide alarm circuit board construction, a parts list, a complete circuit description and more. 

Connect a 1-amp in-line fuse AS CLOSE AS POSSIBLE to your power source. This is VERY IMPORTANT. The fuse is there to protect the wiring – not the alarm. Exactly how the system is fitted will depend on the make of your particular machine – so I’m unable to provide any further help or advice in this regard.The quiescent (standby) current of the circuit is virtually zero – so there is no drain on the battery. If you want to operate the alarm manually use a key-switch or a hidden switch connected to the “off/set” terminals. For automatic operation connect a wire from the ignition circuit to the “ignit” terminal. Then every time you turn-off the ignition – the alarm will set itself. Remember that this wire from the ignition switch is not protected by your 1-amp inline fuse. So unless its run is very short – fit the wire with its own 1-amp fuse as close as possible to its source.Add an Automatic Immobilizer.
