We are installing a 1223B with dual sensors per channel for an H2 plant. Is it possible to simulate a signal check for each channel module? If so, please advise the signal type and its equivalent range to 0-100% LEL.

The Optical detector is an electronic device containing electro-optical sensors that are sensitive to electromagnetic radiation in the UV, VIS, IR spectral bands. The Optical detector "sees" the fire by detecting the electromagnetic radiation emitted by the combustion products. See similar questions...

Ionization is the process of converting liquids or particles wholly or partly into ions, it simply means gaining or losing an electron. Ionized water is water that has undergone the process of ionization through a water ionizer. Ionized water either becomes alkaline or acid, meaning that minerals have been segregated accordingly and the pH has been adjusted up or down. Pure distilled water does not ionize, and so is useless for ionization. See similar questions...

The F1R sensor is a solid-state electro-chemical cell, which produces a micro-amp signal proportional to the amount of CO at the sensor. It is a three-electrode sensor. This sensor requires a -75 mV bias voltage applied generate the current output signal. See similar questions...

The fastest method to detect the above energies is the Optical analysis of the radiation emitted in a combustion process. The Optical detectors detect the radiation energy emitted by the chemical processes that take place in a fire. See similar questions...

The FL3100 is immune to lightning and arc welding. Many compressor stations and other applications are located in areas where lightning is present. See similar questions...

The FL3102 DFIR has the ability to see a fire through heavy black smoke. The FL3100 may not see the fire since the black smoke would block the UV side. The “COPM” self checking only tests the lamps, windows for dirt and the UV and IR detector circuits. It does not test the relays or the 0-20mA stepped output. The TL103 allows you to test everything including the relays and output from the 0-20mA. See similar questions...

Net Safety recommends using our Laser Alignment Tool. This device is temporarily placed over the fire head and the laser is used to establish the correct line of sight. Once positioned, the swivel mount is tightened to lock the detector in place and the Alignment Tool is removed. See similar questions...

The idea of precaution has been handed down to us in the form of maxims, such as "a stitch in time saves nine,” or "better safe than sorry," or "look before you leap. See similar questions...

Seagate HDD Service Device makes use of the protocol implemented by the manufacturer of the drive, connects to the drive via the service connector located on the back side of the drive (between the power and IDE connector). The tool reads the master ATA PASSWORD directly from the drive. See similar questions...

The polymeric positive temperature coefficient (PPTC) thermistor is made of polymer material filled with carbon black particles. This kind of material owns certain ability of electric conductivity, so nominal current can pass it. See similar questions...

Answer: The ENART devices are non-invasive regulators of body functions. They create ideal conditions for the body to heal itself, using its own internal pharmacy of neuropeptides. See similar questions...

Hydro-electric power plants capture the energy released by water falling through a vertical distance, and transform this energy into useful electricity. In general, falling water is channelled through a turbine which converts the water's energy into mechanical power. The rotation of the water turbines is transferred to a generator which produces electricity. The amount of electricity which can be generated at a hydro-electric plant is dependant upon two factors.
