The control panel. Performs the function of receiving and processing signals from other components of the protection to be sent to the monitoring center. In fact, it is such a unit, where all the wires are reduced, the unit that works regardless of anything from power outages there is a battery inside, from damaged keypad is cut off whether or shorted wires plugged whether siren siren and LED. The control panel will still function in the case of receiving a signal from any of the sensors transmit an alarm signal to the panel, either by radio or by GSM, or by wire – for example, by telephone lines. This unit can be installed in tight spaces. In practice – is enough to place it on the ceiling. While the unit gets to the attacker, work at least one sensor and alarm already have time and it is literally just a few seconds to go to the monitoring center. Hack or drown it virtually impossible – the firms themselves provide security services for many years now, they say that their practice this did not occur.
