This detector must be installed in compliance with the system installation manual. The installation must meet the require-
ments of the local Authority Having Jurisdiction (AHJ). The detector offers maximum performance when installed in com-
pliance with the National Fire Protection Association (NFPA); see NFPA Standards 90A, 72, and 101. The National
Electrical Manufacturers Association (NEMA) publishes detailed information on detector spacing, placement, zoning, and
special applications. The Guide for Proper Use of Smoke Detectors in Duct Applications is available from NEMA at 2101
L Street NW, Washington DC 20037.
NOTICE: This manual should be left with the owner/user of this equipment.
IMPORTANT: This detector must be tested and maintained regularly following NFPA 72 requirements. The detector
should be cleaned at least once a year.

GENERAL DESCRIPTION
An HVAC system supplies conditioned air to virtually every area of a building. Smoke introduced into this air duct system
will be distributed to the entire building. Smoke detectors designed for use in air duct systems are used to sense the pres-
ence of smoke in the duct.

    The 14506873-001 Air Duct Detector Housings are used with Honeywell’s model TC807A ionization detector heads and model TC806A photoelectronic detector heads (purchased separately). These two smoke detection methods are com- bined with an efficient housing design that samples air passing through a duct and allows detection of a developing haz- ardous condition.

  • Page 3: Installation Sequence

    STEP 1. VERIFY DUCT AIR FLOW DIRECTION AND VELOCITY The 14506873-001 is designed to be used in air handling systems having air velocities of 500 to 4000 ft (152.5 to 1219 m) per minute. Be sure to check engineering specifications to ensure that the air velocity in the duct falls within these parameters.

  • Page 4: Install The Inlet Tube

    STEP 4. INSTALL INLET TUBE The inlet tube (shown in Figure 3) is identified by a series of air inlet holes on the tube. This tube must be purchased sep- arately. Order the correct length, as specified in Table 1, for the width of the duct where it will be installed. The exhaust tube is molded into the base of the duct housing.

  • Page 5: Ducts More Than 8 Ft. (244 Cm) Wide

    WARNING: In no case should more than 2 air inlet holes be cut off the tube. There must be a minimum of 10 holes in the tube exposed to the air stream. B. INSTALLATION FOR DUCTS MORE THAN 8 (2.4 M) FEET WIDE NOTE: To install inlet tubes in ducts more than 8 feet wide, work must be performed inside the air duct.

    3/8-inch of insulation from the end of the wire, sliding this bare end under the plate, and tightening the clamping plate screw. The 14506873-001 is built for 120/240 VAC or 24 VAC/DC to operate auxiliary functions. See Figure 5A for operating and wiring details.

  • Page 8: Test Procedures

    REMOVE THE PLUGS AFTER TESTING OR THE SENSOR WILL NOT SENSE SMOKE IN THE AIR DUCT. ALARM TESTS Check the detector interconnections before replacing the duct housing cover. Check the 14506873-001 as follows: A. SSDM0204 MAGNET TEST 1. Make sure power is applied to the detector.

  • Page 9: Sensitivity

    Honeywell recommends that a permanent Detector Test Log be set up and maintained for each individual smoke detec- tor in each building. Each detector should be clearly described, with information on the type of detector, the model num- ber, the serial number (if any), the location, and the type of environment.

  • Page 10: Photoelectronic Sensor Cleaning Procedure

    PHOTO UNITS a. Remove detector cover by inserting a small-bladed screwdriv- er into the cover removal slot located approximately 90 REMOVABLE COVER degrees from the test module socket, twisting cover counter- clockwise to remove. See Figure 10. b. Lift the screen from the photo chamber. Vacuum the screen and cover before using clean, compressed air to loosen and blow out any remaining debris.

    LED current. If more than the maximum number of devices are on the same loop, Do NOT use the 14506873-001 for control purposes. Control for duct applications would need to come directly from the control panel or by using control modules.
