Alarms

A security alarm is a system designed to detect intrusion – unauthorized entry – into a building or other area. Security alarms are used in residential, commercial, industrial, and military properties for protection against burglary or property damage, as well as personal protection against intruders.

Some alarm systems serve a single purpose of burglary protection; combination systems provide both fire and intrusion protection. Intrusion alarm systems may also be combined with closed-circuit television surveillance (CCTV) systems to automatically record the activities of intruders, and may interface to access control systems for electrically locked doors. Systems range from small, self-contained noisemakers, to complicated, multiarea systems with computer monitoring and control. It may even include two-way voice which allows communication between the panel and Monitoring station.

Battlefield V
Alarms are gameplay mechanics featured in the War Stories of Battlefield V. Depicted as large radio towers, they are used by alerted enemies to call for reinforcements to an area. In order to prevent this, players can disable alarms either manually or with weapons or by preventing alerted enemies from reaching and activating the alarm.
