Detection

Spot Smoke Detection

These systems use devices that respond to the smoke particles produced by a fire. They operate on the ionization, photoelectric, cloud chamber, or other smoke particle analysis principle of operation. Spot-type smoke detectors use either the ionization principle of operation or the photoelectric principle.

Air Sampling Smoke Detection

An Air Sampling Detector consists of a piping or tubing distribution network that runs from the detector to the area(s) to be protected. An aspiration fan in the detector housing draws air from the protected area back to the detector through air sampling ports, piping, or tubing. At the detector, the air is analyzed for fire products.

Beam Detection

Beam detection has become commonplace within large open areas, such as atriums, warehouses, etc. Beam Detectors are cost effective when compared with using point detection and suitable for heights way above the operating limits of conventional smoke detection.

Duct Detection

Building, fire and life safety codes often require the installation of duct smoke detection in heating, ventilating, and air conditioning (HVAC) ducts for the detection of fires in an HVAC System.

Video Smoke Detection

D-Tec’s Video Smoke Detection (VSD) systems have been developed to overcome many of the problems associated with smoke detection. It provides solutions for previously unsolvable fire detection scenarios, working externally as well as internally and represents a true technological breakthrough in fire detection.

Spot Heat Detection

These systems use heat-responsive devices of either the spot or line type. They are mounted on exposed ceiling surfaces or on a sidewall near the ceiling. Heat detectors are designed to respond when the operating element reaches a predetermined temperature (fixed temperature detector), when the temperature rises at a rate exceeding a predetermined value (rate-of-rise detector), or when the temperature of the air surrounding the device reaches a predetermined level.

Linear Heat Detection

These systems are relatively low cost. Line-type detectors can be installed in a relatively inconspicuous manner by taking advantage of ceiling designs and patterns. (See NFPA 72, National Fire Alarm Code.)

Flame Detection

Flame detectors are solutions for virtually any application where fire may result in a large loss of capital equipment and where risk to personnel is high. Industrial and commercial applications include oil and gas pipelines, turbine enclosures, off-shore platforms, automotive manufacturing facilities, aircraft hangers, munitions plants, nuclear facilities, and many, many more. Other applications include protecting hydrogen filling stations and munitions plants.

Gas Detection

The use of a gas monitoring system, with appropriate action taken if dangerous levels of gases are detected, can help to prevent an explosion or can help to prevent worker injury or exposure to toxic gases. Action can be taken, and initiated automatically by the gas monitor, to help prevent the gas level from rising further. Such action could be the automatic shutoff of gas valves, turning on a ventilation fan, shutting down a process, or audible and visual alarms to alert and evacuate personnel.
