Car alarms with siren included

Siren included

— the presence of a siren in the car alarm delivery set — a module that gives a characteristic sound signal in various situations: an alarm or warning is triggered, arming and disarming, etc. The siren is not an obligatory element of the alarm system: some models allow connection to the car's standard horn, and in systems with two-way communication (see "Type of communication"), a key fob can be responsible for notifications. At the same time, such a module provides a greater variety of signals than a klaxon, and they can be better audible and at the same time less harsh. The siren can also be purchased separately, but having it in the kit is usually more convenient.
