Product Overview

The Siemens ─ Fire Safety Model ‘FDBZ’-series of air-duct-detector housings are

designed for use with Siemens Model ‘H’-series, Cerberus PRO-series and Model

OP121 detectors. (see: Details for Ordering for a complete list of compatible

devices).

Designed for installation directly to heating, ventilating and air-conditioning

(HVAC) duct systems, the Model ‘FDBZ’-series of duct housings complies with

National Fire Protection Association Standard (NFPA) No.’s 72 and 90A, and is

Underwriters’ Laboratories Listed.

When equipped, the air-duct detector housing will signal the presence of smoke

being carried through the duct system. Air-duct detectors are not intended to be

substituted for open-area detection.

Notes: Most conventional time-control equipment guarantee only one (1) detector

per zone when the detector’s operated relay function is critical. The connection of

a remote lamp and a remote relay −per detector − is allowed. Refer to the

installation manual of the respective conventional FACP. With either the Cerberus

PRO series or FireFinder® XLS series of FACPs, up to 252-addressable detectors with

relays per circuit may be used. The connection of an intelligent remote lamp (ILED)

and a remote relay is allowed for each detector simultaneously.

Specifications

The Model ‘FDBZ’-series of air-duct housings are uniquely designed to use with the

photoelectric detector. Sensitivity of Models PE-11, PE-11C, OP121, and 8854

conventional detectors can be verified for calibration via LED visual status or a

Model RSAW-11, Model RSAC-11 or FDBZ492-RTL multi-color remote lamp. A

green flash indicates the detector has passed its self-test. Amber indicates a

Trouble condition, and red indicates an Alarm event.

Sensitivity for Models FP-11, HFP-11, SFP-11, HFPO-11, SFPO-11, OP921, OOH941,

OOHC941, 8710, and 8713 intelligent detectors is verified from the multi-color

LED of the respective detector, or its sensitivity reading may be printed by

command from the corresponding FACP to an optional printer.

Specifications (cont.) The remote alarm indicator (Model FDBZ492-RTL) allows for manual testing via a key-switch for conventional and addressable detectors, as well as the conventional and addressable air-duct housing with relay. Model FDBZ492-RTL, which mounts remotely from the conventional and addressable air-duct housing, allows for manual relay-output control. The duct-detector remote indicator key-switch also indicates the current state of the detector.

Operation Based on the monitoring results, the LED indicator flashes the following colors based on the following conditions: Flash Color Flash Interval (in seconds) Condition Green*: Normal supervisory operation. Smoke sensitivity is within rated limits. Yellow: Detector is in Trouble condition, and needs either repair or replacement. 4 Alarm condition. 1 Red: No Flash: 10 Detector is not powered. ── *LED can be turned OFF. Please follow the corresponding description of the panel used.
