New FIRERAY 3000 Optical Beam Smoke Detector for Wide Area Fire Detection

Fire Fighting Enterprises Ltd., the leader in beam-type fire detection, is pleased to introduce the new FIRERAY 3000 end to end infrared optical beam smoke detector. The detector offers particularly cost effective protection of large, open area spaces and in situations where ceiling-mounting is difficult or inappropriate.

All FIRERAY beam detectors are designed primarily for use in wide open indoor spaces, and offer the benefit of only requiring small numbers of units to cover very large areas – not only affecting the time, cost and complexity of installation, but also the aesthetic impact thereafter. The FIRERAY 3000 is ideal for applications where line of sight for the IR beam path is narrow, or where the building structure uses especially reflective surfaces which may cause complications for reflective beam system installation. Each element of the package has also been designed to be both discreet and aesthetically pleasing, helping them to fit well into every environment from modern architectural buildings to ornately-decorated heritage sites.

Installation is quick and easy, and can be completed by a single operator thanks to a variety of aids and features. A visible targeting laser housed in the receiver head aids initial placement and setup, showing clearly the beam path and therefore the necessary positioning for the units. During commissioning the LEDs on the heads also light up to help fine-tune the alignment path, showing the installer in which direction adjustment is needed. Both of the detector heads have integrated alignment thumbwheels for simple, intuitive and repeatable targeting adjustment, with up to 10 degrees of motion available on both horizontal and vertical axes (90 degrees with an extra accessory bracket).

HWM Leak Detection Equipment Helps Save Water in Mooresville, N.C., USA

The town of Mooresville in North Carolina (USA) has been using HWM leak detection equipment to save time, money and water in its 240 miles of water mains, complying with new state regulations in the process. With the new equipment, Mooresville Public Services Department has found itself able to identify and repair leaks in the distribution network as and when they occur, minimising disruption to both the service and during the maintenance process.

HWM Leak Detection Equipment Helps Save Water in Mooresville, N.C., USA

Mooresville is a town of 33,000 people that provides an average daily flow of 12.2 million litres of water to 13,000 homes and businesses. In the summer of 2008, officials at the town’s Public Services Department were recording a 10% non-metered water rate, and underground water leaks were damaging the road network directly. In addition to this, the extensive digging required to find and repair the leaks obviously came at further cost and caused further disruption and congestion. With the passage of North Carolina House Bill 2499 requiring public water services to develop and implement water conservation measures, as well as new industries moving into the area that would drastically increase water requirements, officials knew it was time to upgrade their water management program.

After evaluating competing products, it was decided that the acoustic leak detection equipment designed and manufactured by HWM was the best match for their operational and budgetary requirements. The order was placed with Fluid Conservation Systems (HWM’s sister company in the USA). Mooresville Public Services Director, John Vest, said: “The FCS equipment was compatible with our record keeping system and simple enough so that the guys in the field could use it and feel confident that they were collecting accurate results.”

Mr. Vest contacted local distributor Carolina Meter & Supply (Hampstead, N.C.) and purchased Permalog leak detecting acoustic noise loggers, L-Mic and X-Mic ground microphones, a MicroCALL+ Digital leak noise correlator*, and a Patroller II system to allow leak data to be collected from a moving patrol vehicle in ‘drive-by’ fashion.

Within 6 months of installing the equipment, Mooresville Public Services staff had located and repaired 24 leaks, saving an estimated total of $80,000 (roughly £50,000) annually. Workers were pinpointing leaks accurately, allowing preventative maintenance work to be scheduled with advance public notification to avoid traffic congestion. “The FCS equipment has really enhanced our planning capabilities. We’re finding leaks before they become a problem”, said Field Operations Supervisor, WD Bumgarner.

Alicat Pressure Controllers Rocket into the Atmosphere

Modified PC Series used in sounding rocket payload attitude control systems

Pressure controllers from Alicat Scientific (www.alicatscientific.com) have been selected for use in NASA sounding rockets to control payload attitude. Alicat PC Series absolute pressure controllers provide the speed, accuracy and durability required for this mission-critical function.

The payload sections of some NASA sounding rockets are required to achieve pointing accuracies of finer than 1 arc second (1/3600 of a degree). Conventional attitude control systems (using solenoid valves) introduce too much shock and vibration, and are imprecise. NASA contractor Northrop Grumman turned to Alicat for a solution that would work with its delicate optical instruments.

The Alicat PC Series absolute pressure controllers are used to directly feed the payload’s attitude control jets. The four pressure controllers are fed from a common gaseous argon manifold at approximately 160 psig, with a stock Alicat mulitdrop RS-232 sending set-point commands to the controllers. As soon as the rocket passes 100 km in altitude, all controllers are brought up to 5 PSIA with both pitch and yaw moments balanced. The spacecraft’s attitude is then modified by modulating the pressure commands sent to the Alicat controllers.

Alicat’s control precision enables commanded pressure changes in increments as small as .00234 psi or as large as 150 psi, with extreme speed. NASA’s testing demonstrated the controllers accurately track a 5 hz sign wave, correlating to a response time faster than 32 milliseconds. As there are no backup systems for attitude control, the Alicat pressure controllers are considered to be mission critical pieces of equipment.

A top choice for a variety of applications, the Alicat PC Series pressure controllers are available with numerous output options in a modular design that delivers fast, accurate and repeatable results. Low power consumption and a rugged design result in lower cost over the course of its long service life. With an industry-leading Lifetime Warranty against defects in materials and workmanship, users can feel confident that their application needs will be met.

To fit NASA’s requirements, the stock PC Series controllers were modified slightly with a different capacitor and connector hardware. To enhance durability and reduce mass, the main electronics board was potted in plastic and the bodies were fabricated from aluminum, rather than the typical stainless steel. The controllers passed NASA testing for shock, vibration, thermal cycling and exposure to vacuum without difficulty, and have completed several successful missions. Northrop Gumman has ordered 28 controllers over a five year period for this application.
