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.

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.

Yes, the advantages over optical flame detection technologies (IR, IR/UV or IR?) includes constant sensitivity of the system across the entire field of view, instant visual verification of the event, the ability to detect smoke and motion.

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

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.

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.

Optical soundtracks (we mentioned them earlier). Almost all of the release formats, including the digital ones have provision for some kind of optical soundtrack, even if only as a backup. The optical soundtrack refers to the two-channel soundtrack that is carried on the optical track of the film release print.

Once your surround sound format has been selected (see the paragraph below for more), you need to order an optical soundtrack negative for the film. In the case of LCRS mixes, a traditional two-channel; Printmaster track is created, and this is sent to an optical sound house for the creation of the optical negative. The optical sound house will record the soundtrack onto 35mm film using a special camera, and some will also develop their own soundtrack masters.

Ultera's Optical RAID controller solutions virtualize an array of optical devices using RAID (Redundant Array of Independent Devices) to operate as a single logical optical drive. Seen by the host as a single optical drive with increased performance, online storage capacity & reliability. Optical Striping (RAID Level 0) increases performance and online storage capacity up to 4 times more than a single optical drive.

Flaming is when someone shouts at another person in a vain attempt to convince them that whatever that other person said or believes in is unconditionally wrong or stupid. Avoid getting into flame wars, and if flamed, laugh it off or ask someone else what you did wrong.

Since knee implants contain metal, there's a chance they could set off metal detectors. Special cards that explain that you have a knee implant are available for you to carry with you to show to security personnel.

Some of the better 'all purpose' detectors can make a pretty good job of most treasure hunting assignments, but there are certain machines specifically designed for such tasks as underwater work and gold nugget hunting. These specialized types are less adaptable to general-purpose work.

Keeping your carbon monoxide detector in good working order with fresh batteries is very important these days. I can't tell you how many times we have responded to a carbon monoxide detector going off only to find the batteries dead. But, if you hear your detector going off, call the fire department and get out of the house. It's better to be a bit embarrassed then dead. They will determine the source and contact the appropriate people to correct the situation.
