Manual fire detector IPR-1-Ex (ИПР-1-Ех) explosion-proof

The IPR-1-Ex (ИПР-1-Ех) manual fire detector is explosion-proof for installation indoors and for outdoor use.

The inclusion of detectors in the fire alarm loop is carried out according to the loop current increase scheme. Switching current - 20 mA, voltage up to 30 V. With explosion protection level "ib", "Intrinsically safe electrical circuit", according to GOST 22782.5, has explosion protection marking 1ExіbІІВТ5 Х, is installed in explosive areas and is intended for manual activation of the signal and fire extinguishing.

Characteristics:
• The detector is designed for both indoor and outdoor use.
• Supply voltage range: 10 ÷ 30 V
• Current consumption in standby mode for detectors Version 3 is no more than 50 μA.
• The minimum current consumed by the detector in the “Fire” mode at a supply voltage of 10 V ≈ 7 mA.
• The maximum current consumed by the detector in the “Fire” mode at a supply voltage of 30 V ≈ 19 mA.
• Detector resistance in standby mode > 100 kOhm.
• Internal resistance of the detector 1.3 kΩ ±10%.
• Overall dimensions of the detector are 90x93x48 mm.
• The weight of the detector assembly is no more than 0.2 kg.
