Fig. 3 Exemplary TUN ‐ 38Ex detector connection to detecting line.
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
may be transmitted.
After the fire alarm is sounded in the control panel or supply ‐ alarming device, warm ‐ up process
should be terminated and the alarm cancelled with the appropriate control panel button or short
detector supply circuit interruption.
8 DETECTOR MAINTENANCE
It is recommended to carry out periodic detector operation checks that cover:
-
overall examination and dust, dirt, cobweb, etc. removal
-
periodic device functioning test.
The TUN ‐ 38Ex detector is required to pass periodic controls, carried out at least once in 6 months, to
prove that the detector operates properly and works together with the fire control panel properly.
Any damaged detector must be passed for repair to the manufacturer.
During renovation or painting works detectors shall be protected from damage or dirt.
9 STORAGE AND TRANSPORTATION
9.1 Storage
The TUN ‐ 38Ex detectors must be kept in individual packages in closed rooms at the temperature of
+5 °C up to +35 °C, relative humidity up to 80%. Surrounding environment shall be free of volatile
compounds of sulphur and acid or alkaline exhausts.
The detectors shall be stored at a minimum distance of 1.5 m from heating elements.
9.2 Transportation
The TUN ‐ 38Ex detectors can be carried with any transport means provided the transport instructions
given on their packing are observed and they are properly protected from any mechanical damage. It
is forbidden to transport the goods at temperatures lower than ‐ 40 °C and higher that +70 °C (at
relative humidity up to 80%) or at relative humidity higher than 95% at temperature of +40 °C.
