PPCT «ALTO 2000»: advantages, applications, principle of operation
Areas of use
PPCT "ALTO-2000" - protection
of premises of industrial facilities, banks, warehouses, underground and
aboveground garages, tunnels, residential and administrative buildings, as well
as other facilities, the conditions for the application of the blocks
correspond to their design.
Fire control devices with control
devices for automatic fire protection devices "ALTO 2000" are
designed for:
• For autonomous work;
• Work in conjunction with the fire
alarm system in the part of receiving notifications from an external fire alarm
(FQP) device, by connecting the contacts of the external PCB relay to the
device loops;
• To connect fire detectors that are
directly connected to fire alarm loops;
• Forming and issuing teams for the
launch of automatic fire extinguishing means in the directions (up to sixteen);
• Management of light and sound
notification;
• To generate a signal to turn off
ventilation and switch on other devices;
• provision of signals about the occurrence of a fire or malfunction in the
trains or devices to the operator and further transfer to the central
monitoring station (CMS).
The number of detectors of any type corresponding to DSTU EN 54-5, DSTU EN
54-7, DSTU EN 54-10, DSTU EN 54-11, DSTU EN 54-12 - up to 32 pieces
simultaneously connected to each loop. (however, the total number of detectors of any type should not exceed 512
pieces per block Alto 2000 CPU);
• Automatic and manual start-up of fire
extinguishing means on separate electric circuits with continuous monitoring of
line integrity (power supply of fire extinguishing means is provided from
specially designed UPS unit);
• Possibility of application with various AUP - aerosol, gas, powder and
others, having means of automatic start-up;
Advantages of PPCT "ALTO 2000"
• The company has an ISO9001: 2008 quality system, so the quality of the
instruments is very high;
• Each block of the device passes 100% input control of parameters and
testing of serviceability, which causes the highest reliability of operation;
• Application of components in the manufacture of components only from
well-known world brands in the field of microelectronics also determines the
highest stability of the characteristics of devices, which also increases their
reliability;
• Ease of configuring the system by applying different numbers and
composition of units. At the same time, the system can be adapted to any
object, based on its individual characteristics.
• Simplicity of work with the device and its maintenance, due to the
thoughtful arrangement of control elements and display elements;
• The tests showed that the temperature characteristics of the units can
range from -30 to +50 degrees Celsius, which completely covers all possible
temperatures for our latitudes;
• The instruments fully comply with the requirements of Table D of Appendix
D of GOST 13109-97 ("Electrical Energy: Electromagnetic Compatibility of
Electricity Generation in General Purpose Power Systems") and can withstand short-term voltage surges up to 400V alternating current.
Operating principle
Fire control devices "ALTO 2000" TU U 31.6-16307479-001: 2006 are
built according to the block principle, which makes it possible to use them in
various versions of applications for fire alarm systems and automatic fire
extinguishing systems of any configuration and complexity.
The device receives signals from thermal, smoke and other types of sensors
included in the AL of the device (these may be the ALTO 2000 CU ALS, or the
Alto 2000 BKP AL), or from the manual start buttons (both external and located
on the front panels "Alto 2000 CP" and "Alto 2000 BKP"),
and generates fire alarm signals (Pozhar !, connected to Alto 2000 CP), and 30
seconds. warning signals before the start-up (NEO "Leave!", connected
to "Alto 2000 OPF"), and warning signals about the supply to the
protected room of the extinguishing agent (NEO "Do not enter!",
connected to the "Alto 2000 BKP").
After expiration of the evacuation time (30 seconds), the fire extinguishing
agent is delivered to the protected premises, extinguishing takes place
directly, and outputs for controlling the ventilation shutdown devices are also
activated on the Alto 2000 CPU and Alto 2000 BKP units.
If there is any malfunction in the system, the output "fault" is
activated.
Schematically, the system in the maximum
configuration is shown in Fig. 1
