Spark, Ember, Smoke and Thermal Detectors
Detectors that use a lead sulfide cell operate in the longer wavelength range and can detect both sparks and embers. Superior detectors use both silicone photocells and lead sulfide cells in one detector and are called combination detectors. Another consideration with detection technology is the viewing angle, cleanability in the flow stream, self-testing capability, and the speed of response in combination with the control unit and water spray deployment or isolation valve or diverter closing time. It is important to have this pretested so that the distance between the detection zone and the water extinguishing zone is in accordance with the manufacturer’s instructions, based also on velocity data and water pressure data for water extinguishing systems.
Spark Detector FSM
- FSM is a new type of high-performance spark detector.
- It combines the properties of a classic spark detector and a residual ember detector.
- This innovation allows for reliable detection of all critical ignition potentials with one detector.
- Improve workplace safety with a reliable detection solution.

Spark Detector FSK
- The FSK-1 (FSK-2) spark detector is an opto-electronic monitoring system and has been developed to detect sparks in the near infrared range. The spark detector is suitable for installation in closed piping systems where no outside light can enter the pipe.
- The spark detector can be installed easily in pipes of different nominal dia/meters (100 – 2000 mm) without any modification of the existing suction system thanks to its special housing. Inspection flaps for maintenance work are not required. Installation diameter is 40 mmand is quickly cut with a special hole-cutter.
- Maximum ambient temperature should not exceed 60° C.
- The spark detector is designed to protection class IP 65.

By-Pass Smoke Detector BRM1
- By-pass smoke detectors are installed in exhaust air ducts and on the cleaned gas side of filter housings in order to prevent filter fires.
- Air is extracted continually from the system being monitored by a series of pipes, and fed to an optical smoke detector.
- In the event of an alarm, the filter system can be switched off or an extinguishing device activated.

Thermal Detector THM1
- Overheating of material, which could lead to a fire, or temperature in creases during the production process, are monitored by thermal detectors.
- In the event of an alarm, the filter system can be switched off or an extinguishing device activated.
