Fire detector МДПИ-028, t = 90 ° C

Fire detector МДПИ-028 is intended for fire detection by changing the ambient temperature in the protected room in two ways:

- when the temperature reaches the threshold;

- by the rate of temperature change.

Consists of two (open 1 and closed 2) bimetallic spirals and a contact system 8, placed in one housing. One of the spirals is closed by a perforated casing that freely allows heated air to pass through, and the other is protected by a casing 3 and closed for air access.

Detector contacts open.
The maximum permissible current through the contacts is 30mA at a voltage of (24 ± 2) VDC.
The detector is operational when:
- vibrations with a frequency of 20Hz with an amplitude of 1 mm;
- shaking with a frequency of 80 to 120 beats per minute and an acceleration of 70 m / s 2 ;
- roll with a roll up to 45 ° and a differential up to 15 °, as well as with a long roll up to 15 ° (the least period is 60 sec.);
- ambient temperature from minus 40 to plus 50 ° C;
- relative humidity 98% at 25 ° C (relative humidity 98% at 35 ° C).
Main dimensions of the detector & nbsp; МДПИ-028 , mm., no more: 105х130х104.
Detector weight & nbsp; МДПИ-028 , kg, no more: 0.5.
