1 PURPOSE is designed for detection of fire hazard or fire appearance The TUN‐38Ex Heat Detector warning in closed rooms, where during the first phase of fire an occurrence of temperature rise may be observed, or where – due to various reasons – temperature may exceed the set fire danger level. It is provided for working together in fire detecting lines with control panels manufactured by POLON‐ALFA or by other producers that obtained POLON‐ALFA’s compatibility confirmation. The detector’s operational temperature is between ‐ 25 °C and + 50 °C for A1 class and + 65 °C for B class. The TUN‐38Ex heat detectors are connected to fire detecting lines through intrinsically safe barrier or separator of the following parameters: Uo ≤ 25 V, Io ≤ 99 mA. The detectors are installed in rooms and zones qualified as 1 and 2 explosive hazard category resulting from potential explosion danger ... -

It is obligatory to utilize intrinsically safe barrier or separator (named in the control panel Operational Manual) in intrinsically safe detecting lines. After installing all detectors, the control panel or supplying apparatus should be switched on. Every detector must be individually checked. It is not recommend to warm up more than one detector in one detecting line. In case more than three detectors in one detecting line are warmed up at the same time a false damage (short circuit) signal ... - Page 9 IK‐E280‐001GB 9 Fig. 4 TUN‐38Ex detector basic dimensions IK‐E280‐001GB/07.2009 ...
