Volumetric Alarm* (Exclusive!)
Click on the Picture or here to open in a new window! Diferentely from the majority of the Alarms you know this inedited project of Esquemas.org measures instantly minimal variations of atmospheric volume in a determined environment made by, for example, the simple opening of a door, or even by the breakage of a little window-pane. Fed by Rechargeable Batteries with a connected recharger and controled remotely, it includes still visual indicators of state (Leds), sensitivity control, weak batteries indicator, possibility of a delay in the shooting, exit to the dialer and auto- reconnection after 2 hours (to avoid discomfort with the neighbours when you go out). These are some of the excellent features of this Project and it could only have the stamp of www.esquemas.org ! In the remote control: 1 Bip turns on the Alarm 2 Bips turn off the Alarm
This Alarm can be adapted for automotive use, in a very efficient manner, because as it’s fed independently, after any instruction of the thieves to try openning the doors, it discharges the Alarm and there isn’t any way to do that. It’s important to note that if this is its application, it would be very interesting to put it in a little reinforced metallic box to make impossible to break it at the time of the theft.
