Car alarms with silent arming mode

Silent arming mode

— the name of this function is due to the fact that the alarm does not beep in this mode — which can be useful, for example, when setting the car at night in the yard of a multi-storey building. In one-way models with a quiet mode, the warning is carried out only by light signals (headlights); in bilateral, usually, a notification is sent to a key fob or mobile phone (if there is a GSM module).
