COMBINED DETECTOR IP 212101-116.4-A1 REDUT MK-OP

Combined detectors are designed for installation in places where it is impossible to unambiguously predict the occurrence and development of a fire (primary occurrence of smoke or temperature increase). Smoke chamber dust compensation ensures that the detector sensitivity remains at the set level and the absence of false alarms, and also significantly increases the operating periods between maintenance. The detector complies with TR EAEU 043/2017.

The detectors are designed for operation at an ambient temperature from minus 40°C to plus 75°C, climatic version UHL category 2, relative humidity 93% at a temperature not exceeding 400C. Atmospheric pressure from 84 to 106.7 kPa. Seals and connections of structural elements of the detector housing provide the degree of protection in accordance with GOST 14254-2015 (IEC 60529:2013) "Degree of protection provided by shells (IP code)" of the switching compartment - not lower than IP67; smoke chamber - not lower than IP31.

Case material - corrosion-resistant stainless steel 12X18H10T.

According to the method of protecting a person from electric shock, the detector corresponds to class III according to GOST 50571.3.

The detectors comply with the norms and requirements of electromagnetic compatibility in accordance with GOST R 53325 with a degree of test severity 2. Radio interference from the detector does not exceed the standards established by GOST 30805.22 for class B equipment.

IP 212/101-116.4-A1 Redoubt MK-OP - N is a maximum-differential action detector and can be used in short circuit alarm loops (parallel connection).

The detectors are equipped with two cable glands of the KV, KV series TU 27.33.13-359-81888935-2019. Connecting thread of cable glands M20x1.5. Cable glands allow you to enter and exit round cables of various diameters:

for open laying of the attached cable (index in the designation - K);
for laying the attached cable in a pipe with an internal or external thread G1 / 2 or M20x1.5 (TN1 / 2, TV1 / 2, TH20, TV20);
for connecting an armored cable with a double seal (B);
for connecting a cable in a metal hose RZTSH-10mm, RZTSKh-12mm, RZTSKh-15mm or RZTSKh-20mm (KM10, KM12, KM15, KM20

The detectors are connected in parallel to the alarm loop (AL), taking into account the polarity. The alarm notification is provided by a complex of two signals: electric, expressed in an increase in current through the detector, and light - the red LED turns on.
The performance of the detector is maintained when exposed to background illumination from artificial and (or) natural lighting of at least 12,000 lx.
The detector operation signal is stored after the end of exposure to combustion products and (or) heat. The detector is returned to the standby mode by switching off or changing the polarity of the detector supply voltage for at least 1.5 seconds from the control panel.
The detector has a built-in optical indication of high brightness - a constant glow of the red LED.
Monitoring the detector's performance in standby mode is provided by a short flash of the LED with a repetition period of 4 seconds. Indication of malfunction and dustiness of the chamber: indication operation modes are given in Table 1.
