If no test gas is available to conduct functional testing, remove
cover and, while holding down the cover removal switch, blow
smoke from a smoldering cotton wick or punk directly at the
head to cause an alarm. The alarm indicator on the detector
should illuminate within one minute.
Refer to the PE-11 Installation Instructions, P/N 315-094198, the
PE-11C Installation Instructions, P/N 315-095626, the 8854
Installation Instructions, P/N 315-094198FA, or the OP121
Installation Instructions, P/N A6V10281367, as applicable, for
additional information on testing these detectors.
MAINTENANCE This unit is equipped with cover removal switch (SW1) that
instantly provides a trouble condition upon removal of the clear
cover. For all testing and inspection with the cover removed, the
cover removal switch (designated as SW1 on PCB) must be
manually depressed to simulate normal operation.
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 mainte-
nance program should consist of periodic cleaning of dust from
the detector head by using a vacuum cleaner. For cleaning, refer
to the PE-11 Installation Instructions, P/N 315-094198, the PE-11C
Installation Instructions, P/N 315-095626, or the 8854 Installation
Instructions, P/N 315-094198FA.

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
