KASATKA Fire Alarm System is a computerized analogue addressable system of data collection and processing designed to automatically detect fire and pre-fire situations, generate alarm and warning signals sending them to external circuits, transmit current data on fire hazard situation in the monitored premises to interfaced devices and in case of fire, provide crew guidance and control fire doors based on pre-set algorithms.

The system includes:
ЦП (TsP) device for data collection, processing and display
ЦПИ (TsPI) central information panel
ВПИ (VPI) remote information panel
ПСИ-1 (PSI-1) data collection and display panel
ПСИ-2 (PSI-2) data collection panel
Flame, infrared, smoke and gas detectors and combined detectors
Fire door control devices

Power supply:
main 380 V 50 Hz three-phase
or 220 V 50 Hz one-phase
backup 24 V DC
emergency 24 V from embedded power source

Addressable devices:
Q-ty Up to 5,481

Power consumption:
main 200 VA
backup 150 W

Response threshold:
Infrared detectors (temperature)

54–78 °С for detectors with a threshold of 65 °С
80-100 °С for detectors with a threshold of 90 °С
Smoke detectors (optical density)

2.5–12.5% for detectors with a threshold of 12.5%
12.5-50% for detectors with a threshold of 50%
Flame detectors (distance to the fire source)

10 m in case of fire with an area equivalent to that of a 0.1 m2 kerosene fire
Operating temperature -25-55 °С for ИПР (IPR) and ИПТМ (IPTM) detectors
0-40 °С for ЦП, ВПИ and ПСИ devices
0-45 °С for the rest of devices, detectors and sensors
Relative humidity 98% at 35 °С
