Alarm System "R-2K11"
Description and application
R-2K11 is alarm central, designed for signaling of unauthorized access in indoor areas. It has been developed with conventional integrated circuits, which allows high suitability for repair and easy maintenance. It is equipped with autonomous battery power, which is not included in the kit. Under the armored cover, fitted with tamper detection, is located a powerful internal siren.
The siren is possible to be switched off, by using a jumper. The installation is made through the technological holes in the bottom of the metal box.
The central has three unbalanced security zones, in order to connect different sensors, operated in normally closed contact in unactuated state. The zones are:
- First zone (I) – Delay zone, when the alarm is activated, for entering and leaving the secured area
- Second zone (II) – When this zone is accessed, the activated central goes in alarm mode instantly
- Third area (AS) - 24-hour zone with continuous security mode, regardless of whether the central is switched on or off
Interface and front panel
- Electro-mechanical lock with two keys. Switch position "on / off" is duplicated with glowing red LEDs "ACTIVATE"
- Indicators for zone's status
- Green LEDs I and II provide information for the status of the zones, namely
- Lights up continuously, when a sensor has registered movement in the corresponding zone
- Do not light up, when there is no movement in the zones
- They flash up, when there has been uncontrolled access in the areas, while the central is switched on, i.e. there is stored alarm activity in the memory. Clearing the stored alarm, i.e. stopping the LEDs flashing, is done only when the central is disarmed and by pressing the "RESET" button
- The red LEDs, located near the green LEDs I and II, inform the exclusion of the zones. Exclusion of the corresponding zone is performed by using the buttons I and II "EXCLUSION ZONE"
- CAUTION: Disabling both zones simultaneously, is equal to disarming the whole system!
- Red LED indicator "ALARM": lights up, when the central is in alarm cycle, which is switched off by the electro-mechanical switch on the front panel
- Green LED " ~ 220 V": lights up, when the central is supplied with power voltage. If the protective fuse, mounted on the bottom of the box is burned out, this LED does not light
Technical characteristics

- Output float and management of autonomous external siren: voltage + 12 V / 1 A, which goes off in "ALARM" mode
- Output for triggering an external non autonomous siren or other devices: voltage + 12 V / 1 A, which appears in "ALARM" mode
- Non-powered, galvanically separated relay output + 12 V / 10 A: it switches on, when the central is switched on
- Built-in siren with modulated sound: 120 dB, triggered in "ALARM" mode
- Possibility to exclude (switch off) zones by the use of the external buttons, located on the front panel
