In a vast range of car alarms has recently introduced a good system Mongoose Duplex 3D models with the function of a pager device, remote audio message to the key FOB that the car owner of unauthorized door opening, engine start, shock the body, etc., a Distance alert in the face of massive urban development (on example of Saint-Petersburg, Russia) not less than 300 m. In the daily operation of the alarm system with a pager is convenient because the alarm comes on, the bidirectional remote control unit (RCU) is a key chain held by the owner of the car (except for a loud audible alarm in the vehicle which can be reprogrammed for quiet mode). Thus, there is no need to jump to the car or to the window each time it is triggered car alarms, worrying for his “swallow” (it is known that the set of sound signals of various alarm systems is no different variety). If it works it is “your” alarms — this will be seen by the alarm on your remote-the keychain remote, and the flash indicator LEDs will indicate a specific area of the triggered zone of protection. It agree, it is convenient.
