Description
FDBZ492
S54319-B22-A1
A two-wire addressable or conventional duct detector (without relays) designed for direct
use on heating, ventilating and air-conditioning (HVAC) air-duct systems. When
equipped, the air-duct detector housing will signal the presence of smoke being carried
through the duct system.
For use with the following Models:
▪ 8710
▪ 8854
▪ 8713
▪ OP121
▪ OOH941
▪ OOHC941
▪ FP-11
▪ HFP-11
▪ HFPO-11
▪ PE-11
▪ PE-11C
▪ SFP-11
▪ SFPO-11
FDBZ492-HR
S54319-B23-A1
A two-wire addressable duct detector (with relays) designed for direct use to HVAC air-
duct systems and works with the Remote Test Switch (FDBZ492-RTL). This part has a
programmable relay base, and when equipped, the addressable air-duct detector housing
will signal the presence of smoke being carried through the duct system.
For use with the following Models:
▪ 8710
▪ 8713
▪ OOH941
▪ OOHC941
▪ OP921
▪ FP-11
▪ HFP-11
▪ HFPO-11
▪ SFPO-11
▪ SFP-11
FDBZ492-R
S54319-B24-A1
A two-wire conventional duct detector with relays designed for direct use on HVAC air-
duct systems. This detector has a relay base, and when equipped with conventional air-
duct housing, will signal the presence of smoke being carried through the duct system.
For use with the following Models:
▪ PE-11 PE-11C
▪ OP121
FDBZ492-PR
S54319-B25-A1
A four-wire conventional duct detector with relays and a built-in power supply. Housing is
designed for direct use to HVAC air-duct systems. It has a relay base with a built-in power
source. When equipped with conventional air-duct housing, this duct detector will signal
the presence of smoke being carried through the duct system.
For use with the following Models:
▪ PE-11 PE-11C
▪ OP121
FDBZ492-RTL
S54319-S27-A1
Device is used for manual testing via a key-switch for duct-housing Models FDBZ492-R,
FDBZ492-PR and FDBZ492-HR. Device mounts remotely from the conventional and
addressable air-duct housing, allowing for manual relay-output control. The duct-detector
remote key-switch also indicates the current state of the detector.
For use with the following Models:
▪ FDBZ492-HR
▪ FDBZ492-R
▪ FDBZ492-PR
FDBZ-WT
S54319-B26-A1
An optional, separate watertight NEMA 4X enclosure (Model FDBZ-WT) that provides
added watertight protection for any of the Model FDBZ492-series duct housings. The duct
housing fits into the separate 4X enclosure. This part allows the air-duct detector housing
to be installed in the separate enclosure, and can be used in either an outdoor area or in
environments where excessive moisture is prevalent.
For use with the following Models:
▪ FDBZ492
▪ FDBZ492-R
▪ FDBZ492-HR
▪ FDBZ492-PR
