into consideration when determining area protection. Refer to
the Initiating Devices chapter of NFPA Standard 72 for Loca-
tion and Spacing requirements for specific types of construc-
tion; e.g. beam, suspended, level, sloped and peaked ceilings.
TEMPERATURE – HUMIDITY – PRESSURE – AIR VELOCITY
The temperature range for the HFPO-11 detector is 32°F (0°C)
to 100°F (38°C). Use the detector in environments where the
humidity does not exceed 93% (non-condensing). Normal
changes of atmospheric pressure do not affect detector sensi-
tivity. The air velocity range is 0-4000 ft/min for open areas
applications. Follow detector spacing and location requirements
in NFPA 72 Chapter 5 for
High Air Movement Areas
and
Con-
trol of Smoke Spread.
When installing Model HFPO-11 in existing installations with
an existing duct detector housing, order an AD-11UK Air Duct
Upgrade Kit DA-304, P/N 500-695967 and use it in that instal-
lation. This kit includes the required housing cover, P/N 305-
095676. Do not use Model HFPO-11 with any other air duct
cover.
For air duct and open area applications, the
HFPO-11 smoke sensitivity range is indicated on
its nameplate.
OPERATION
LED Indicators
The Model HFPO-11 contains an LED indicator capable of
flashing either one of three distinct colors: green, yellow, or
red. During each flash interval, the microprocessor-based
detector checks the following:
• For smoke in its sensing chamber
• That its smoke sensitivity is within the range indi-
cated on the nameplate label
• That its critical smoke sensing electronics are
operating.
Based on the results of these checks, the LED indicator flashes
the following:
DETECTOR PROGRAMMING
Each detector must be programmed to respond to a unique
system address.
• To program the detector address, use the Model DPU
Device Programming Unit. Refer to the DPU Manual,
P/N 315-033260.
• Record the loop and device number (system address)
for the detector on the detector label and on the base
to prevent installing the detector in the wrong base.
The optional DPU label printer can be used for this
purpose.
Detector Guard Programming
When using the DGH-11 or the STI 8100IS detector guards
with with the FireFinder-XLS system, program the HFPO-11
for DUCT Application using the Zeus Programming Tool. For
FS-250/FS-500 systems, program the HFPO-11 for DUCT Ap-
plication using the FS-CT2 Configuration Tool.
WIRING
Detector bases for Model HFPO-11 should be connected as
shown in Figure 2.
Detector Mounting
To ensure proper installation of the detector head into the base,
be sure the wires are properly dressed at installation:
• Position all wires flat against the base.
• Take up all slack in the outlet box
• Route wires away from connector terminals.
To Install Detector Head:
• Align LED in detector with LED symbol on base and
insert detector into base.
• Rotate detector counterclockwise while gently press-
ing on it until the detector seats fully into base.
• Then rotate the detector clockwise until it stops and
locks in place. Insert optional locking screw (Order
Model LK-11).
To Remove Detector Head:
• Loosen locking screw, if installed. Then rotate the de-
tector counter clockwise until stop is reached.
• Pull detector out of base.
DETECTOR TESTING
Only qualified service personnel should test. To assure proper
operation of the detector, both the Sensitivity and Functional
Test should be conducted. The minimum test schedule may be
found in the current edition of NFPA 72.
