Explosion-proof manual fire detectors of the IPR 512 HORIZONT (IPR) series are used in fire alarm and fire extinguishing systems and are designed to manually turn on a fire alarm signal in an explosive zone.
Manual announcers belong to electrical equipment of group I, subgroups IIC and IIIC according to GOST 31610.0-2014 (IEC 60079-0) and are intended for use in explosive gas environments, including mines and mines, as well as explosive dust environments. The detector complies with the requirements of TR TS 012/2011, GOST R IEC 60079-14 and other regulatory documents governing the use of electrical equipment in hazardous areas.
IPR explosion protection marking for groups II and III in an aluminum alloy and stainless steel case - 1Ex db IIC T6 Gb / Ex tb IIIC T85 ° C Db (GOST IEC 60079-1-2013, GOST IEC 60079-31-2013). For groups I and III in a stainless steel case РВ Ex db I Mb / Ex tb IIIC Т85°C Db (GOST IEC 60079-1-2013, GOST IEC 60079-31-2013).
The ambient temperature for manual call points and remote starters is from minus 60°С to plus 75°С. Type of climatic version UHL (NF) and HL (F) of category 1, atmosphere type II-IV according to GOST 15150, and relative humidity of air 100% at a temperature of not more than 250C and 95% without condensation at a temperature of not more than 400C. The degree of protection of the shell is IP66/IP67 according to GOST 14254.
The principle of operation of the IPR is optoelectronic, which allows you to completely eliminate the influence of external electromagnetic fields on the operation of the detector. Devices can be installed on any surface, including ferromagnetic. The drive element is made in the form of a button.
According to the case material - IPR are made of aluminum alloy AK12OCH and stainless steel AISI 321.
According to the connection method, IPRs are produced in addressable and non-addressed versions. Connection schemes: addressable - four-wire with a separate power line; addressless - two-wire or four-wire.
In the non-address version, the "Fire" notification can be transmitted either by increasing the current of the alarm loop (two-wire circuit), or using an electromechanical relay with switched contacts (four-wire circuit with a separate power line). The "Fire" current for a two-wire connection can be set using an additional resistor during installation.
In the addressable version, a four-wire connection scheme with a separate power line is used. Compatible address systems: "S2000 Orion"; "Frontier".
IPR are compatible with almost any control and reception devices.
Indication of the standby mode and the "Fire" mode is carried out using the LED indicator, respectively: by rare short flashes or a constant glow of red.
