automatic fire alarm design for an apartment building
Our design organization has developed a working documentation for the automatic fire alarm system for an apartment building (residential complex).
DESIGNING FIRE ALARM SYSTEM
1. In this working documentation, the fire alarm system and the warning of the MHI fire (limited mobility groups) for the new construction of the NB1.3 building are made. For the fire alarm system, technical equipment is used by ISO "Orion" ZAO NVP "Bolid" (Russia). The address-analogue fire alarm system is based on the two-wire "S2000-KDL" communication controllers installed in SDR floor cabinets (1. ЗСА1,1.3АС5,1.3АС7)
2. In the fire alarm MGN warning system, it is planned to install the Exit light blinking sirens on floors 1-7, the fire-safe zone on the floor and boards on floors 2-7.
3. To receive information on the response of the fire extinguishing installations, liquid flow indicator devices (ALE) are used, which are connected to the DPLS line through the “S2000-AP2" address expander.
4. To control the opening of fire hydrants, fire-fighting position sensors (DPC) are installed in the cabinets of the PC. A signal to open a fire hydrant is transmitted to the fire alarm system. For the remote start of smoke protection ventilation, a manual start button (SB) is installed in the PC cabinets. The position sensor of the fire hydrant (DPC) and the button for manual start of smoke removal (SB) are included in the fire alarm system through the address C2000-AP2. "
5. To detect a fire in the residential premises of apartments located below 15m above the ground, autonomousSmoke fire detectors IP212-50M2. In residential premises of apartments located above the level of 15m above the ground, common areas, administrative and public premises of the basement, 1 .... 7 floors, point-specific smoke analogue detectors IP2-3-3А-О1-02 are installed. The "Fire" signal is generated and the engineering systems are managed in case of a fire by a signal from a single analogue analogue compressed detector, in accordance with paragraph 14.2 of St. Petersburg. 13130.2009 with Change 1. Compliance of IP212-34A analogue addressable fire detectors - () and) 2) to the requirements of clause 13.3.3 of St. Petersburg. 13130.2009 with Izm1 is confirmed by a letter of the developer of the standard, VNIIPO EMERCOM of Russia No. 12-4-02 / 5876 of December 8, 2009 (Appendix No. 1), the requirements of the application RkSP5.13130.2009 with Izm1 ODUL Confirmed by the letter of the manufacturer No. 88 of January 25, 2012 (Appendix No. 2). Manual escape fire detectors are installed on the escape routes in the building. To activate light alarms in the fire (flashing flashing beacons) installed at the emergency exits and at the fireproof zone, the S2000-SP2 unit isp.02 of the Orion ISO are used for people with limited mobility.Light Exit annunciators are fireproof zone permanently on.
6. The controllers and ISO "Orion" units are interconnected via the RS-485 interface and connected to the S2000M control and management console.
The “S2000M” monitoring and control panels of the fire alarm system are located in the premises with the staff on duty, who are on duty around the clock - the SPZ CPU (pos. -109) located in the basement floor (mark -3.000) of the NB1 building . 1. When a single analogue smoke alarm detector, or one hand-held fire detector in the evacuation path, is triggered in the protected room, the fire alarm system issues a “Fire” signal to the S2000M control panel and to the PC AWM Orion Pro screen and generates command impulses to control engineering systems in case of fire, see volume VII, book. 3 (pr. TSZH-RD-01,3-AK. 12, "Automation of smoke protection and fire-retarding valves, management of engineering systems in case of fire ')
PROJECT-BUDGET DOCUMENTATION OF FIRE ALARM SYSTEM
The power supply of electrical receivers of automatic fire alarm systems is carried out according to the I category of reliability from two independent sources after the ATS according to section 4.3 of St. Petersburg. 13130.2013 Rechargeable batteries of Orion ISO backup power sources are used as a backup power source, the battery capacity provides uninterrupted power supply for installations for at least 24 hours in standby mode and at least 1 hour in Alarm mode. Electric power supply for automatic fire extinguishing installations and internal fire-prevention water supply system, fire alarm for building NB1.3 see section ЦЖ-РД-01.1-01.2-01,3-02-03-ЭОМ.
For the characteristics of electrical wiring, see cable journal with pipe stocking list (see sheets TSZH-RD-01.3-AK.11-017, TsZH-RD-01.3-AK.11-018, TsZH-RD-01.3-AK.11-019). When passing through interfloor ceilings for fire insulation of cable-carrying routes, fire-resistant cable penetrations are used (see Album CJSC DKS "" Typical solutions for constructing fire-resistant cable penetrations with the use of (extender C20). Products of CJSC DKS. " with foam DF1201). in parallel laying open away from the wires and cables with voltage up to 60V to power and lighting cables should be at least 0.5 m. 000. wiring performed in PVC tubes (gesture their smooth) on the wall at a height of at least 2.2m from the floor and ceilings.
