the FC901 Manual, P/N A6V10336754, as applicable.) The
HFP-11, HFPO-11, SFP-11 and SFPO-11 are polarity insensi-
tive detectors. Line 1 and Line 2 can be either line of the
loop.
Note any limitations on the number of detectors and
restrictions on the use of remote devices permitted for each
circuit.
When replacing a detector with a different model, be aware
that existing detector accessories connected to the base or
air duct housing that were compatible with the old detector
may not be compatible with the new detector. Always read
the Installation Instructions accompanying the detector to
determine detector and accessory compatibility.
Installation Of Smoke Detectors
To Install:
•
Remove cover by loosening the four screws. Take off the
cover and set it aside.
•
Align detector with base and insert detector.
•
Rotate detector clockwise while gently pressing on it
until the detector drops fully into base.
•
Then rotate the detector clockwise until it stops and
snaps in place.
•
Replace cover and tighten the four screws.
To Remove:
•
Rotate the detector counterclockwise until stop is
reached.
•
Pull detector out of base.
TESTING
Only qualified service personnel should test these units. To
assure proper operation of the detector and control panel,
both the Sensitivity and the Functional tests should be
conducted. The minimum test schedule may be found in the
current edition of NFPA 72 for installations in the U.S. and
CAN/ULC-S537, The Verification of Fire Alarm Systems, for
installation in Canada.
Sensitivity Test
The PE-11/-11C detector monitors its smoke sensitivity
automatically and requires no test equipment. A green flash
of the detector LED about every seven seconds indicates
that the smoke sensitivity is within its listed limits.
