PHOTOELECTRIC DUCT DETECTOR, P/N 63-1057
PHOTOELECTRIC SMOKE DETECTOR WITH ISOLATOR,
P/N 63-1062
The Photoelectric Duct Detector (See Exhibit 3-28) is an intelligent,
spot-type smoke detector that utilizes the light obscuration principle
to detect smoke. The detector is designed for use inside the duct
detector housing only and should not be used for open area
applications. The detector includes a tri-color LED for instant
indication of device status. The isolator version provides complete
short circuit isolation for NFPA Class X wiring when used with an
isolator base.
The following modes of operation for the detector are configurable to
suit your specific project requirements:
Alarm Verification
Drift Compensation
PreAlarm 1
Walktest
PreAlarm 2
Device Summing
Acclimate
Remote Annunciator
Day/Night Sensitivity
Note:
Photo Duct Detector can be programmed as a Supervisory
input as required by some Local Authority Having Jurisdictions
(AHJ).

DUCT DETECTOR HOUSING, P/N 63-1158
The Duct housing (See Exhibit 3-29) is equipped with an integral
base for mounting either the P/N 63-1057 or P/N 63-1062 duct
detectors. The housing provides a remote alarm output for use
with auxiliary devices, such as the remote LED annunciator and
remote test stations. Unlike similar DUCT detectors, separate
24VDC is NOT required.
Five different lengths of sampling tube are available for
penetrating into the DUCT:
P/N 63-1159 = up to 1ft. (0.3m) ducts
P/N 63-1160 = 1ft. – 2ft. (0.3m – 0.6m) ducts
P/N 63-1161 = 2ft. – 4ft. (0.6m – 1.2m) ducts
P/N 63-1162 = 4ft. - 8ft. (1.2m – 2.4m) ducts
P/N 63-1163 = 8ft. – 12ft. (2.4m – 3.7m) ducts
Important Note:
Duct Detector and Housing must ordered separately and both are required.
Refer to Section 3.8 for accessory devices that can be used in conjunction with the duct detector housing to
provide remote testing and visual notification options.
