  • Bosch D296 24V Projected Beam Smoke Detector Bosch D297 12 V Projected Beam Smoke Detector
    The D296 Projected Beam Smoke Detector is used in clear open structures such as arenas, atriums, auditoriums, ballrooms, churches, factories, museums, and warehouses. Each D296 detector consists of a transmitter, a receiver, and a remote annunciation plate. Because the transmitter and receiver typically mount on the ceiling or high on walls or columns, they provide an effective and unobtrusive means of supervising public areas for fire protection. The D306 Remote Indicator Plate, included with the D296, provides a convenient means of verifying detector status. Install it anywhere within 100 ft (30 m) of the beam receiver. The D306 has LEDs to indicate normal, trouble, and alarm conditions, and test points to monitor the detector circuit.
  • Operates over distances between 30 ft (9 m) and 350 ft (107 m)
  • Six levels of switch-selectable sensitivity
  • Built-in alignment sights and tamper protection
  • Automatic range adjustment, signal synchronization, and contamination adjustment

  • Description
    The Model 30-3003D uses air sampling tubes to provide a cross sectional sampling of air moving through the duct. Inlet sampling tubes are available in four lengths: one foot, three feet, six feet, and ten feet.
    The length of the inlet sampling tube is determined by the width of the duct to be monitored. The inlet duct, therefore, specify the shortest sampling tube that is at least the width of the duct to be protected. It can then be cut to the exact length at the job site.
    Outlet tubes are one common length. Both inlet and outlet tubes are furnished with each detector.
    The Harrington Model 30-3003D Explosion-Proof Air Duct Smoke Detector is designed to detect the presence of smoke for the primary purpose of controlling blowers and dampers in air conditioning and ventilation systems and is intended for use in hazardous industrial and commercial locations. The unit mounts directly to heating, ventilating, and air conditioning ducts and utilizes a cross sectional sampling tube arrangement rather than a substitute for open area detection.
    The explosion-proof air duct smoke detector is intended to be connected to a control unit and function as part of a fire protection system. The 30-3003D is designed for use with a 4-wire system fire alarm control panel (2 wires for detector power and 2 wires for detector output).
    The detector operates on the forward light scattering principle, a technology that is based on more than 30 years of experience in advanced photoelectric detection systems.

    DESCRIPTION

        The Fenwal Series DH-60 Air Duct Smoke Detector is designed for detecting particles of combustion in air handling systems. The DH-60 Duct Detector housing accepts the Fenwal Advanced CPD-7054D Ionization and PSD-7157D Photoelectric Smoke Detector Heads. Upon detection of smoke levels at the set point of the detector, the DH-60 Duct Detector can control a variety of devices, such as HVAC fans and dampers to prevent the spread of smoke throughout the facility.
  •  
  • High amperage relay contacts are provided for controlling such devices in the event of a fire. Supervisory contacts are also provided for signaling unit faults. A transparent Lexan cover over the detection chamber allows visual inspection of the duct detector’s chamber and the internal smoke detector status. Sampling is accomplished by sampling tubes that extend into the HVAC duct.

  • The DH-60 Duct Detector can operate as a 24 VAC, 120 VAC or 240 VAC powered stand-alone device or as a 4-wire 24 VDC powered device for use with Fire Alarm Control Panels. An integral normally energized trouble relay is used to supervise power and smoke detector head removal. Outputs provided can accommodate remote alarm and power indication, remote test and remote reset. Fenwal offers a range of remote accessories that operate in conjunction with the duct detectors. Figure 1 is a simplified parts breakdown of the DH-60 Air Duct Smoke Detector.
  •  
  • APPLICATION

    The Fenwal Series DH-60 Duct Detectors are suited for use with HVAC systems in commercial, industrial and institutional fire alarm applications.The DH-60 is easily mounted to both rectangular and round ducts from 8 inches (200 mm) to 12 feet (3.6 m) wide and is compatible with all ducts with air velocities between 500 and 4000 feet per minute (2.5 to 20 m/s). The Ionization and Photoelectric Smoke Detector heads listed above operate over this entire air velocity range.

    SAMPLING TUBES

    The operation of the DH-60 Duct Detector is based upon an air sampling principle. Two tubes extend into the HVAC duct to transport air from inside the duct into the duct detector sensing chamber and back out to the duct. If the sampled air contains a concentration of smoke greater than or equal to the alarm threshold of the internal smoke detector, the unit will alarm. The duct detector inlet supply sampling tube is selected according to the size of the HVAC duct. A separate exhaust tube is not required since an integral tube is molded into the housing to simplify installation.

    REMOTE INDICATORS/CONTROLS

    A series of easily installed remote indicators are available to add versatility and flexibility to the Fenwal Series DH-60 Duct Detectors. These attractive and functional devices provide convenient status information along with remote Test/Reset capabilities. The remote indicators are helpful when the detector is out of view or mounted in relatively inaccessible locations. The remote indicators can be used in both AC and DC applications. Figure 2 shows the faceplates of the RA-911, RA-912 and RA-913 remote indicator controls.

    FUNCTIONAL TESTING AND SENSITIVITY MEASUREMENT

    The Fenwal DH-60 Duct Detectors should be tested upon installation and once a year thereafter as stated in NFPA 72. All alarm signal devices, releasing devices, and extinguishing systems, as applicable should be disengaged before the test is performed and re-engaged at the conclusion of testing.The DH-60 Duct Detector may be functionally tested either by introducing smoke into the detector or activating the magnet test.
  •  
  •  Two separate magnet-locating slots are provided on the outside of the duct detector housing.Further, as stated in NFPA 72, Detector sensitivity should be checked within one year of installation and every alternative year thereafter. Fenwal offers the Model DST-003 handheld wireless infrared sensitivity tester that allows the sensitivity of installed operating detectors to be measured from the floor level. For details, please refer Fenwal Document 70.103.
