System operation algorithm

Automatic fire alarm is designed to detect the source of fire.

In standby mode, with automatic fire alarm system "Warta 1/832" activated, it provides continuous control of the fire situation in the premises, which are protected using fire detectors.

Algorithm of operation of thermal fire sensors: when the air temperature in the monitored room increases, the loop resistance changes, which causes the corresponding PPKOP alarm loop to operate at the receiving station.

Algorithm of operation of smoke sensors: when the transparency of the air in the room protected by the sensor changes, the loop resistance changes, which causes the corresponding alarm loop to be activated on the PCIP and an alarm is issued.

Algorithm of operation of smoke linear sensors: when smoke attenuates the flow of IR radiation between BI and BP by a given number of times, the detector generates a "Fire" notification.

In case of fire, actuation or malfunction of the automatic control system installation, sound and light alarms are activated, forced ventilation is switched off and signals are transmitted to the fire department PCP.

PPKOP "Warta 1/832", smoke, linear, tame announcers are calculated on work within temperatures from - 25 wasps to +60os and relative humidity up to 90%. Considering characteristic of the main flammable materials which are in the protected rooms and a class of potential of explosion according to PUE in the project the installation with thermal fire announcers of "IPK7", manual "IPR1m", smoke "IPK8", smoke linear ArtonDL allowed for use is accepted.

Deviations from the design during installation of fire alarm units are not allowed without coordination with the state fire supervision bodies.

Purpose of the device

The device is part of the fire or fire alarm system and is designed to receive information from firefighters and (or) security detectors, to convert and evaluate this information and generate warning signals about the possibility of a fire, about the occurrence of a fire, about unauthorized opening of a protected object or a malfunction in the system both for direct perception by a person and for further transmission of signals and issuing commands to other devices.

Device is related to PSK of medium information capacity and has eight, sixteen, twenty-four or thirty-two loops

alarms (depending on the completeness of the delivery) to which active and passive unattended fire and security detectors certified in Ukraine can be connected.

The device allows setting of SB operation modes, operating modes of actuating relays, memorizing initial states of SB with power of remote unit of FPU in dialog mode, displaying alphanumeric information on LCD and entering information when pressing the corresponding keyboard button.

The device provides automatic short-term disconnection and release of fire alarm system at detection of "FIRE" state with output of "WARNING to SBS" message for shutdown time, and subsequent interval of waiting for repeated operation of this SBS, at detection of which "FIRE" message will be output.
