At the disconnected accumulator plant submit a supply and, selecting resistor R6, install on an output of the accumulator rectifier pressure 6,75 V.Vmesto batteries short-term connect the resistor resistance 10 Ohm capacity of 2 W and measure a current flowing through it. It should not exceed 0,4 … 0,45 A.Izmerjajut pressure 6 In and 3,6 In on an output of stabilizators DA2 and DÀÇ accordingly, as a last resort select resistors R15 and R26 for adjustment of these values.
For check of serviceability of all device include phone - the transmitter and dial phone number on which it will be necessary to phone.
the Board of a security signaling, phone and the accumulator plant are installed in the general strong plastic case. LEDs (5 pieces) are carried out on the front panel of the case (for reserve LEDs can and to be installed). Sealed-contact SF2 can be allocated as in the case and outside in a reserved place. Sensor SF1 allocate on a doorway jamb if the signaling is used indoors, or use the regular door cutout if it is the car. In an autovariant it is desirable to use already available security automobile signaling together with a described signaling device, submitting high level at actuating of an available signaling on lower under the circuit an input of element DD1.4 of a logical node of control closing of button "Call" of phone (thus disconnect sensor SF1 and resistor R16).
Also in the case fix a microphone and the receiver inset derived from the case of phone. In the case bore through two small holes and from within paste to these holes a microphone and the receiver inset. A supply 12 In submit on the unit through a connector allocated on a lateral surface of the case. In an authoring variant to a basic variant of a security signaling (fig. 1), are added two node: the driving sensor (on the circuit it is not shown) and the speech unit (fig. 2).
the Digital output of the sensor of driving is connected to lower under the circuit to an input of element DD1.4 (thus disconnect sensor SF1 and resistor R16). At driving origin in a sensor operative range, on input RS of the trigger there is a high level that leads to start of the multivibrator and the counter of a logical node.
the Speech unit (fig. 2) is intended for a phrase pronunciation "System is activated, please abandon a location" at system activation (a charm present to the sealed-contact at an output from a location). However, it is possible to write down for playback and any other phrase, at will. Speech [4 unit consists of a record chip - displays of speech DD1 and power amplifier DA1. The technique of record of speech 1416Ð is presented to chip ISD in [4]. At an output from a location, bringing a magnetic charm to sealed-contact SF2, on an output 12 triggers DD3 appear high level. Thus on an output 24 DD1 the speech unit there is a low level that leads to playback of the vocal phrase which have been written down earlier in chip DD1.
the Sensor of driving and the speech unit are installed also in general casing of system.
the printed circuit board Type is resulted on fig. 3 and fig. 4.
Network connection points are shown on fig. 5.
Lacks described above a security signaling are defined in the core by lacks GSM of communication networks.
