Adjustable Mounting, Beam Sensitivity, and Delay Timer 4 "C" Relays Voice Alert System-6: How It Works Voice Alert System-6 is a patented wireless annunciator. It allows voice-recorded messages to identify activity for up to six monitored zones. Voice Alert uses wireless, passive infrared sensor/transmitters (PIR's) with an indoor receiver/speaker (Base Unit). When movement is detected ... A radio signal is sent from the PIR to the remote Base Unit. A custom message, which you've recorded in your own voice for that specific zone, is played on the Base Unit. One of four "C" relays attached to the Base Unit can optionally be triggered (see example below). With its ability to secure up to six separate zones, each with its own customized recorded message in your own voice, Voice Alert is the most flexible system available. Residential Scenarios Driveway Alarm - play back "Car coming up the driveway."   Car Alarm - A sensor in your car on the street, if someone breaks the glass it will alert you inside your home, car alarms dont scare anyone, this allows you to call the police as soon as something happens.    Talking Door Sensor - Know when someone comes near your door or rear house entrance.  Play back "Someone's on the patio" and trigger a floodlight using one of the four "C" relays included on the Base Unit.   Pool Alarm - Use a sensor near the pool and have it play back "Kids are by the pool."   Animal Alarm for your Garden -  At night have it play back "deer in the garden" and know when deer or rabits enter or come near your garden.    Protect your tool box in your truck - Put a sensor in your tool box and know when someone opens your tool box on your truck, stop theft.    Alert yourself when anyone with heat enters a particular area, Infrared technology detects heat from any source.    System-6 can monitor all four zones simultaneously and still have two additional zones available (along with their own custom messages), if required. Commercial Examples Zone 1 could monitor a loading dock and play back "Delivery arriving" when triggered.   Zone 2 could monitor a counter area or front desk. When triggered, this Zone might play back "Customer out front."   Zone 3 could be used to monitor a restricted area in a store. When this PIR detects movement, the Base Unit plays back "Someone's in the storeroom," for example.   The applications are endless. System-6 can monitor all three zones simultaneously and still have three additional zones available if needed. Users can place the wireless sensors wherever needed and alter their recorded messages at any time. Voice Alert System-6 sets up in minutes and can be completely customized to handle tough wiring situations. The wireless PIR features adjustable mounting and beam patterns, all-weather protection, and can send a signal up to 1000 feet in open space (or 300 feet through walls). Multiple base units may also be used to trigger alerts in two or more areas simultaneously.
