One of the most important ancillary tools is the alarm of powerful sirens. The stronger the siren or the so-called power (W) or watts can produce a stronger sound, this sound causes confusion and panic to thieves and causes escape. They become.
So in choosing the siren, which at first glance may not be important, you must be very careful.
What are the ways to choose a strong siren?
Of course, the first step is to choose between two sirens, just test them with a 12-volt anti-theft battery. Just pay attention to their positive (red) and negative (black) that the wrong connection of the siren will burn the internal board, the second step The choice between two alarm sirens is based on their weight, because one of the factors in the strength of sirens is their internal magnet, which the larger it is, the more ohms it produces and the more power it consumes, resulting in a louder sound, although the internal range of the siren is also one. It is an important factor that can only be examined in the first step described. .
The question is, can a single internal speaker be used for the alarm?
The answer is that you must first consider the two alarm alarm output factors:
The first is the output power of the alarm, which is between 25 watts to 45 watts, which further damages the alarm board of the alarm device.
Second, the ohm tolerance of the siren board is 8 ohms, and apart from the above specifications, an amplifier is needed
Note that the alarm output of the alarm is only for the alarm because the power output gives 12 volts !!!.
