Smoke detector RM 3000IS EX / Heat detector WM 3000IS EX
For use in hazardous areas
Characteristics
- The RM 3000IS EX smoke detector is a stray light detector with integrated thermal sensor
- The RM 3000IS EX smoke detectors and WM 3000IS EX heat detectors are intrinsically safe
- In hazardous areas they may only be used in combination with a shunt safety barrier
- Important: They must be replaced after a maximum of 8 years of operational life to ensure the correct functioning of the hold-open system
- In Germany, the DIN 14677 regulates the replacement obligation of fire detectors in hold-open systems

Installation
Installation
The wiring is done in the S 3000IS EX base. In the last detector, the 5,6 kΩ resistor has to be installed between the clamps Com- and Out+.
Intrinsically safe circuits (components marked light-blue) may be placed in hazardous areas, depending on the type of protection required. However, it has to be made sure that each intrinsically safe circuit is safely separated from any not intrinsically safe circuit. The demands of the EN 60079-14 standard must be observed. In Germany, the “National Preamble” of the DIN EN 60079-14/VDE 0165 part 1 must also be applied.
On demand, an additional parallel display can be connected to the RM/WM 3000IS EX smoke/heat detectors to locate the triggered detector or the seat of the fire faster in case of alarm.
