Security alarm systems consist of central panel, security sensors and control panel.

Central panel collects and analyzes data obtained, and performs pre-programmed functions which are activated after sensor triggering.

Control panel displays alarm status, allows its programming, and is used for activation and deactivation of security mode for objects. Basic configuration of equipment also has to include an uninterruptible power supply and cable network.

Security alarm systems can have the following sensors:

volumetric;
magnetic-and-contact (reed switches);
acoustic;
vibrational;
ultrasonic;
radiological;
capacitive;
with directional detection diagram.
The procedure of installation of security alarm system is as follows:

Expert's visit for site inspection and premises examination for security purposes.
Creation of threat scenarios.
Determination of the type of security alarm system.
Elaboration of system design.
Equipment supply.
Installation and startup-and-adjustment.
Testing and maintenance.
It is recommended to install security systems in combination with fire alarm system (which would allow significant cost cutting for installation of two independent systems) and with video surveillance system, for the purpose of full control of events occurring in secured areas.

Also, it is preferable to provide for control and access management system at this initial stage as well
