• Receipt and fulfillment of external commands on initiation and removal of security.
• Change over to security mode or training mode upon an external command.
• Programming parameters in training mode.
• Notification of circuits’ situation on external request (for the system SCARaccess).
• Provision of trouble-free operation of power supply in case of trouble of external feeding for more than 24 hours.
• Grouping of sensors’ circuits (security zones) in groups.

• Central processor SCARalarm Processor;

It is assigned to collect circuits’interrogation data from circuit current situation spread-out and storage units, as well as history of their variation. Each sensor circuit corresponds to certain security zone. Security zones could be united in groups. SCARalarm Processor receives requests for application/removal of security from the Keyboard Unit. Requests for application/removal of security are produced by SCARalarm Keyboard Unit. Each security zone (group of zones) is assigned with programmed SCARalarm Keyboard Unit list, which indicates authorities to request application/removal of security. 8 successive interfaces RS-485 provide cooperation with spread-out units and security application/removal units.

It is assigned to interrogate sensor circuits (of security zones) and to transfer circuits situations to central processor of SCARalarm Processor. SCARalarm Zone Unit has receptacles for connection sensor circuits and their feeding. SCARalarm Zone Unit is made in two versions: SCARalarm Zone Unit 8 – for servicing 8 security zones and SCARalarm Zone Unit 16 – for servicing 16 security zones. Data exchange from SCARalarm Processor performs due to minutes RS-485.

It is assigned to transfer requests for application or removal of security of secured zone, corresponded to sensors’ circuit or of group of zones. SCARalarm Keyboard Unit D is manufactured as single security zone (group of zones), as well as security remote control board - SCARalarm Keyboard Unit PD. The second version presumes feeding to LCD information, concerning situation of digital interfaces SCARalarm Processor, situation of SCARalarm Zone Unit and the keyboard has a provision for programming any security zone, group. Data exchange from SCARalarm Processor performs due to minutes RS-485.

It is assigned for control with the use of relay outputs of the type “dry contact” upon commands of SCARalarm Processor. The relays are designed for the DC current not less than 2 А with the voltage of 12 V. One relay is designed for the DC current 10 А. Data exchange from SCARalarm Processor performs due to minutes RS-485.

It is assigned to convert AC 220 V, 50 Hz to DC 12 V for feeding units of the system SCARalarm. In the case of failure of the external power supply SCARpower Unit provides feeding from the internal power source for not less than 24 hours. The internal reserve source are lead-acid cells 12 V with the capacity from 48 tо 100 Аmper-hours. In presence of external power supply SCARpower Unit provides charging of internal cells.

It is assigned for warning by means of the text message on preset numbers in case of application/removal of security, triggering of secured zones’ sensors. The transfer parameters, list of numbers and text of message performs with the use of SIM-card and mobile-phone. Data exchange from SCARalarm Processor performs due to minutes RS-485.

The central processor with PC interface module for representation of the current situation of the security system is assigned for processing of server requests concerning the situation and report of the current situation of security zones. Data exchange from the situations’ interrogation server performs due to minutes TCP/IP.

The central processor with PC interface module for programming parameters is assigned for changing over of SCARalarm Processor to the mode of training and back, for programming parameters.to control the access being on, the module requests user’s name and its identification. The module is a web-server for processing a text minute http (use over any browser).

The interface module to connect the access control SCARaccess is assigned for processing of requests and production of situations of security zones while there is an access request appeared. Data exchange from the situations’ interrogation server performs due to minutes TCP/IP.

It is assigned for the situations’ interrogation of security zones SCARalarm Processor, recording of current situations and their variations (record of variations), as well as for notification of monitoring automated working places in case of any variation of security zones’ situation. Database Oracle 9 i and higher are used as a data base control system. Data exchange from SCARalarm Processor (The central processor with PC interface module for representation of current situations of the security system) performs due to minutes TCP/ IP. Data exchange with automated working places performs due to minutes TCP/IP.

Automated working place (АWP) of the current situation’s monitoring of security system is assigned for monitoring of security zones’ and devices situation, which form the system (performance, situation of communication channels). The current situation is determined upon the information from the data base, recorded by the data collecting server. Variation of situations is controlled by the data collecting server’s commands. Data exchange from the situations’ interrogation server performs due to minutes TCP/IP.
