The FP-11/-11C, HFP-11 and HFPO-11 detectors can also be
tested individually using the DPU. Refer to the DPU Manual,
P/N 315-033260. The SFP-11 and SFPO-11 detectors can be
tested individually using the SDPU. Refer to the SDPU
Manual, P/N 315-033260C.
MAINTENANCE The performance of the air duct detector unit may be
adversely affected by dirt or foreign matter on the sampling
tubes or detector. If the air holes in the input sampling tube
become restricted, the unit cannot receive a proper air
sample, and performance is impaired. It is recommended
that the sampling tubes be checked and cleaned periodically.
The detector maintenance program should consist of
periodic cleaning of dust from the detector head by using a
vacuum cleaner. For cleaning Models PE-11, PE-11C, FP-11,
FP-11C, HFP-11, HFPO-11, SFP-11 or SFPO-11, refer to the
detector’s Installation Instructions (See Table A).
The cleaning and test program is recommended for 6 month
intervals, or more frequently, if needed, depending on the
individual detector environment. Consult your local code and
AHJ requirements for required maintenance schedules.
