Detects incandescent bodies flying inside dust collection ducts. It is usually combined with an automatic extinguishing system to extinguish every spark that runs in front of the detector.
Its use is recommended in factories where wood is processed, in textile industry, in cereal and animal feed mills and storage, in the treatment of hides and leather, etc, and where sparks are produced and they can start a fire.
Immediate response time (20-30ms).
Typical sensitivity: 1mm spark at half a meter distance.
“Teletest” feature for remote testing of the detector.
Power supply 24Vdc 50mA.
The air purging unit model APU-874G is a mask in plastic material designed to be applied in front of the spark detector RIV-601P/S mounting unit SAM-871 for application on ducts and conveyors in order to prevent by means of a continuous air jet a dust build-up over the optical window of the mounting unit SAM-871, that could decrease or even blind the detector sensitivity.
Designed to operate and monitor all the functions of a system. On front panel it displays the operating state of the system.
MEMORY function: the alarm signaling LEDs of the detectors and of the flow switch “remember” the alarm occurred blinking until the manual reset (RESET). Reverse polarity and overload/short circuit warning lights are also present.
In case of activation of the STOP circuit, the RESET button stops the alarm and restores the normal operating conditions. The TEST button is used to check the system. Cast aluminium case, IP66 protection. Voltage 24Vdc 36W.
Allows to monitor two independent detection points.
The alarm of the spark detector activates the STOP circuit (it turns on the alarm, stops the fan and closes the duct valve) which is held active until manual reset through the RESET button.
The TEST button is used to check the system.
It carries on the front panels alarm, power, overload/short circuit and reverse polarity lights.
Cast aluminium case, IP66 protection.
Voltage 24Vdc 36W.
Designed to operate and monitor all the functions of a complete spark detection and extinguishing system. The front panel displays the operating state of the spark detectors, water flow switch, STOP function and power supply.
MEMORY function: alarm LEDs of the detectors and flow switch remain blinking until manual RESET. The built-in Alarm Log stores up to 500 events for each detector, flow switch and system test, recording date, time and alarm duration.
The TEST button allows the system to be checked, while the RESET button stops the alarm and restores normal operating conditions. Reverse polarity and overload/short circuit warning lights are also provided.
Cast aluminium case, IP66 protection. 24Vdc power supply, 36W max.
Audible visual alarm.
Indoor and outdoor use.
IP65 protection.
Power voltage 24Vdc 110mA
Opens water flow to the extinguisher spray nozzle.
Coupling 3/4″ female.
Weatherproof protection with IP65 connector.
Power voltage 24Vdc 12W.
To be installed upstream of the EVS-811 water solenoid valve in order to filter out impurities present in the water supply, thus preventing clogging or damage to the solenoid valve’s internal diaphragm.
70° hollow cone jet, spray jet in line with water entry.
To be mounted on surface of ductwork.
It is used in applications where it is necessary to avoid bulky in the duct because of the type and the quantity of transported material (eg fibers, paper, leather).
Coupling 3/4″ gas male, case material brass.
Designed to test the RIV-601P/S spark detector window integrity against dust and dirt build-up.
Its use is recommended when internal test cannot be reliable bacause of window being covered or darkened.
It is mounted like a spark detector, using the same SAM-871 mounting unit, over the duct in the opposite position, so as it will be in front of the spark detector.
Power voltage 24Vdc 50mA.
