Category of PU of the facility on reliability of power supply (as per PUE) - the second .
4. Equipment placement
4.1 Installation and installation of the control and receiving device, fire detectors
perform in accordance with NPB 882001and RD 78.14593, technical documentation
for used equipment and PUE.
"Granit8" 1 pcs be placed in the existing security room at a height of 1.8 from the floor level.
6.1 Design elements of electrical equipment for automatic fire alarm and warning and evacuation systems in case of fire meet the requirements of GOST 12.2.007 for the method of protecting a person from electric shock.
6.2 Protective grounding of electrical equipment of the automatic fire alarm system shall be performed in accordance with the requirements of PUE, SNiP 3.05.06, GOST 12.1.030. all metal parts of equipment that are not formally energized, but which may be under it due to insulation violation, fire automatics devices and panels, electrical equipment cabinets, are subject to grounding. Protective grounding resistance shall not exceed 4.0 Ohm.
Connect all grounding wires to the common grounding circuit of the building, refer to RD 78.14593. Protective grounding (grounding) of automatic fire alarm electrical equipment is performed in accordance with PUE, SNiP 3.05.06, GOST 12.1.030 and technical documentation of the manufacturer.
6.3 Grounding of control and receiving devices shall be performed by copper wire section. 1.5 mm2 by connecting to the internal ground loop of the building.
7. Fire warning system.
7.1. In accordance with NPB 10403, a fire warning system is provided in the premises, determined according to Tables 1 and 2 of the type, which includes NBO "Exit" light annunciators, Oriole sound annunciators installed on escape routes from protected premises according to the layout of CO equipment. For light-and-sound warning, the Mayak12K combined sound and light signalling device is also used, installed on the outside of the wall of the warehouse at a height of 2.5 meters. All annunciators are connected by the KSPV 4 × 0.5 mm wire strictly in series according to the CO loop wiring plans.
7.2. Organization of fire warning zones.
Organization of EMSS warning areas is carried out taking into account the support
safe evacuation of people in case of fire, structural features of the building,
functional assignment of rooms.
7.3. When fire alarm detectors of "FIRE" alert are activated, as well as the command to start: light annunciators of "Exit" NBO, sound annunciators of "Oriolga" in the corresponding warning area, as well as to the combined device of sound and light signalling "Mayak12K."
7.4. In case of alarm detectors actuation, the control and receiving device outputs "ALARM" signal.
