Contents Of The Duct Detector Housing Kit - Honeywell 14506873-001 Installation Instructions Manual

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. When sufficient smoke is sensed, an alarm signal is initiated at the fire control panel monitoring the
detector, and appropriate action can be taken to shut off fans and blowers, change over air handling systems, etc. This
can prevent the distribution of toxic smoke and fire gases throughout the areas served by the duct system.
The 14506873-001s are built to operate on 120/240 VAC or 24 VAC/DC. Two form-C (SPDT) sets of relay contacts are
available for control purposes. Two LEDs on each detector latch on to provide a local alarm indication. Remote alarm
indication is made possible by utilizing the auxiliary alarm output (Figure 5). The duct detector can be tested and alarm
can be reset by using the correct respective code commands from the panel. See panel instructions for details.

CONTENTS OF THE DUCT DETECTOR HOUSING KIT

The 14506873-001 Air Duct Detector Housings consist of the following items: (See Figure 1.)
See Note 1 for Inlet Sampling
Tube and Detector Supply
information.
1. Complete housing base
and cover assembly.
2. Two #10 sheet metal mounting screws.
3. Two sampling tube filters.
4. One test magnet.
5. Drilling template.
6. Two 5/16-inch O-rings.
7. Two foam gaskets.
8. Four #6 self-tapping mounting
screws for the sampling tube.
9. One filter adapter.
10. One inlet tube end plug.
11. Two #10 speed nuts.
Note 1: The inlet sampling tube must be ordered separately. It must be the correct length for the width of the duct where
it will be installed. See Table 1 to determine the inlet tube required for different duct widths. A smoke detector
head (TC807A for ionization or TC806A for photoelectronic) must be ordered separately.
