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.

If you just want to get all the comfort of logging, without much overhead, use Stealth Loggers.

Yes! Net Safety Flame Detectors have internal DIP Switches you can set to a 3, 4, 5 or 6 seconds delay or high/low sensitivity. Consult the User Manual for detailed instructions.

Yes! The all Net Safety flame detectors are housed in a NEMA 4X enclosure suitable for indoor or outdoor installations.

All Net Safety Flame detectors are certified CSA/NRTL for Canada and the U.S. and Factory Mutual performance certified for fire alarm systems (3260). They are also ATEX certified for the European market.

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.

First connect one rope to a solid structure (such as a ceiling beam or a tree branch). To that, connect the suspension frame/rig at height where the suspendee will be off the ground, but is low enough that they can step off a chair or a table beneath them can be lowered. When the suspension is over, they step back onto the chair.

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.

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.

Open "CT Atlas". A menu will appear on the left side of the window with a list of all of the predefined CT maps. Click "Begin Printing" at the bottom of the list. See page 6 of "The Colorado Trail Users Guide" included in the CD box for further information on the CTAtlas.

The best way is to just ADD raw fruits and veggies to your daily diet. The more raw you add the less cooked you will eat. Also read as much about raw foods as possible, try local Raw restaurants, experiment with making some raw dishes on your own.

Basically you (raw) write the three floppy images to disks, put the base tarball on a (FAT) partition some how, boot from disk 1, follow the prompt, mount the DOS partition, and then follow the rest of the INSTALL file. A full set of instructions can be found in the INSTALL file in the distribution.

In addition to category-based levels and appender thresholds, Log::Log4perl supports system-wide logging thresholds. This is the minimum level the system will require of any logging events in order for them to make it through to any configured appenders. anywhere in your configuration file will limit any output to any appender to events with priority of ERROR or higher (ERROR or FATAL that is).

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.

The best way to extinguish the flame is with a "snuffer". Many times when you blow out a candle the melted wax will splatter onto your furniture surface. When positioning a snuffer over the flame you trap the oxygen causing the flame to go out.
