INTELLIGENT DETECTORS
The Cheetah Xi system uses intelligent detectors that not only include all necessary processing for decision
making but also include the control logic for the system, greatly reducing the importance of the central
controller. The operating parameters are downloaded to the devices during system configuration into
nonvolatile memory.
The intelligent, addressable detectors are connected to and receive their operating power (15-30VDC) from
the host control panel via the panel’s signaling line circuits (SLC). Each SLC loop is capable of supporting up
to 254 addressable devices in any combination of detectors and modules. Each addressable device is
assigned a unique SLC address that allows it to be identified not only by the system controller for device
supervision, but by other SLC devices as well to facilitate peer to peer system operation. A brief description
of each intelligent detector and its features is provided in this section for reference purposes.
Refer to Fike document P/N 06-356-2, “Cheetah Xi Operations Manual” for details of detector operation and
available programming features.
Refer to installation and maintenance instructions supplied with each detector for more information.
Note:
Detector electronics are rated 32

F (0

C), 10- 93% relative humidity, unless otherwise
noted.
3.6.1
PHOTOELECTRIC SMOKE DETECTOR, P/N 63-1052
PHOTOELECTRIC SMOKE DETECTOR WITH ISOLATOR,
P/N 63-1058
The Photoelectric Smoke Detector (See Exhibit 3-30) is an
intelligent, spot-type smoke detector that utilizes the light obscuration
principle to detect smoke. 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
3.6.2
IONIZATION SMOKE DETECTOR, P/N 67-033
IONIZATION DETECTOR WITH ISOLATOR, P/N 67-034
The Ionization Smoke Detector (See Exhibit 3-31) is an intelligent,
spot-type smoke detector that utilizes the ionization principle to
detect smoke. 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
