3.6.3 PHOTO/HEAT COMBINATION DETECTOR, P/N 63-1053
PHOTO/HEAT DETECTOR WITH ISOLATOR, P/N 63-1059
The Photo/Heat Detector (See Exhibit 3-26) is an intelligent, spot-
type smoke detector that utilizes the light obscuration principle to
detect smoke. In addition to the photoelectric sensing chamber, the
detector is equipped with a thermistor based, 135°F heat detection
circuit. 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:
Note: Photo element of detector can be programmed as
Supervisory and Heat element for Alarm.
3.6.4 HEAT DETECTOR, P/N 60-1039
HEAT DETECTOR WITH ISOLATOR, P/N 60-1040
The Heat Detector (See Exhibit 3-27) is a spot-type detector,
designed to be programmable for a set-point range of 135-174°F
(57.2-78.9°C) for ordinary detection or 175-190°F (79.4-87.8°C) for
intermediate detection. Detectors in the ordinary range may be
programmed for either fixed temperature or 15°F (9.4°C) rate of rise
operation. Detectors in the intermediate range are Fixed
temperature only. The detection set-point is software programmable
in five degree increments from 135-190°F (57.2-87.8°C). 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:
