Programming Specifications/Requirements For Intelligent System Control Panels.
NOTE: Models TC807A and TC806A can be used with the 14506873-001 if the following constraints are observed:
1. There may be a limit to the number of devices per zone that can have their LEDs latched on. The number of devices
is determined by the control panel and its ability to supply 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. If sensor models TC807A1036, TC807A1044,
TC806A1037, or TC806A1052 are used, the constraints above do not apply.
2. The duct control circuitry (auxiliary relay contacts and auxiliary alarm output) may change states if the sensor is test-
ed and the LED is turned on for more than 4 seconds. If the LED is latched on for less than 4 seconds, the control
circuitry of the 14506873-001 will NOT operate.
3. The panel must not continuously poll the same unit for more than 4 seconds or the auxiliary relay and auxiliary alarm
output may switch states. After 4 seconds of continual polling of a device, the panel must wait a minimum of 100ms
before polling or communicating to that same device.
4. Communications must not cease for more than 3 seconds without an additional clock pulse (after Pulse Width 5) to
turn off the LED on the sensor.
5. To allow the auxiliary relay and auxiliary alarm output to return to a standby condition, (after being in alarm) the panel
must wait a minimum of 100ms after turning off the sensor LED before communicating with that device again.

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.
The currents shown for the
14506873-001 are maximum val-
ues with no accessories.
* All accessory currents are
additional to 14506873-001.
There are no additional cur-
rents for accessories in stand-
by.
