Alerting with light and sound sirens is a simple and reliable means of scaring away an attacker. The sale of sirens is more specific to firefighters, the volume of siren installations in building a fire alarm system is much higher than when creating a security system, but this does not prevent security companies from moving on and creating more and more perfect models of sirens. Firefighters are limited by the rules and can not take advantage of the charms, for example, of wireless sirens with a modern design.
Installation of warning devices is simple enough and not labor-consuming, in this case most of the time is spent not on installation, but on the choice of the siren, as the existing range of equipment offered by the market is quite large. This suggests that even if you did not take care of purchasing several devices, at the time of installation of the security alarm system, it will be possible to increase their number independently by preliminary agreeing their actions with the security service.
The alarm siren can be either sound or light-sound. Recently, the consumer gives preference to the latter and not because of the calculation for increased efficiency in light notification, but rather because of the possibility of using the siren’s light portion, as an indicator of the confirmation of the transition of the alarm system to the security mode.
It is important to remember that sirens are an integral component of any security system. First of all, the sound of the siren affects the psyche of the attacker, while simultaneously informing about the penetration.
A wide variety of means of warning, designed for outdoor installation, allows you to choose the option with the desired characteristics. External sirens, made in a waterproof enclosure, provide the possibility of installation in a variety of places, that is, where they will be most effective.
