Intelligent Suppression Control/Fire Alarm System
PEGAsys
3-11
3-3.10 Field Devices
The SmartOne Series of Intelligent Fire Alarm devices provide
the PEGAsys control system with smoke & heat detection, nec-
essary monitoring and control functions required by today’s ad-
vanced Fire Alarm systems. Each of the SmartOne devices
features an intrinsic microprocessor with 4K of nonvolatile
memory. Each device constantly monitors its surrounding envi-
ronment and makes decisions in response to that information
then reports status as required to the control panel. Each loop
device communicates with the RX/TX module over the PC
(power/communications) line.
This “Distributed Intelligence” architecture allows each loop de-
vice to make decisions within the monitored area. This unique
utilization of processing power makes possible a system of loop
devices with greater capacity and flexibility than any typical ad-
dressable device system with centralized processing.
Each SmartOne device contains a status LED which blinks in
various patterns to indicate device status. The blink rates and
associated status levels are as follows:
Blink Rate Operation status
9 Second Rate Normal mode
2 Second Rate Alarm (activated)
Off (not blinking) Trouble condition
The following three paragraphs describe each type of available
detector. A typical detector is shown in Figure 3-12.
3-3.11 SmartOne Ionization Detectors
The SmartOne Ionization smoke detectors provide true distrib-
uted intelligence addressable microprocessor based smoke de-
tection to the PEGAsys system. Model CPD-7052 is a dual
chamber analog ionization type detector which senses both vis-
ible and invisible smoke. A unique sensing chamber permits
360° smoke entry and response. Each detector is electronically
addressable and can be fully field programmed. Calibration, de-
vice address, pre-alarm & alarm sensitivity set points and drift
compensation algorithm are stored in each detectors non vola-
tile memory.
SmartOne Ionization detectors have an unobtrusive low profile
look and are available using the following:
• Model CPD 7052 SmartOne Ionization Detector:
P/N 70-402001-100
3-3.12 SmartOne Photoelectric Detectors
The SmartOne Photoelectric smoke detectors provide true dis-
tributed intelligence addressable microprocessor based smoke
detection to the PEGAsys system. Model PSD-7152 is a ana-
log photoelectric type detector which responds to a broad range
of smoldering and flaming type fires. A unique sensing cham-
ber permits 360° smoke entry and response. Each detector is
electronically addressable and can be fully field programmed.
Calibration, device address, pre-alarm & alarm sensitivity set
points and drift compensation algorithm are stored in each
detector's nonvolatile memory.
SmartOne photoelectric detectors have an unobtrusive low pro-
file look and are available using the following:
• Model PSD 7152 SmartOne Photoelectric Detector:
P/N 71-402001-100

3-3.13 SmartOne Heat Detectors
The SmartOne heat detectors provide true distributed intelli-
gence addressable microprocessor based heat detection to the
PEGAsys system. Model THD-7252 is a analog fixed tempera-
ture thermistor type detector which does not respond to rate of
rise conditions until its programmed set point is met. Unique
algorithms are used to compensate for heat rise without prob-
lems associated with false alarms due to elevated rates of rise
in ambient temperature.
A unique sensing chamber permits 360° heat entry and re-
sponse. Each detector is electronically addressable and can
be fully field programmed. Calibration, device address, pre-alarm
& alarm sensitivity set points and drift compensation algorithm
are stored in each detector's nonvolatile memory.
SmartOne Heat detectors have an unobtrusive low-profile look
and are available using the following:
• Model THD 7252 SmartOne Heat Detector:
P/N 70-404001-100
3-3.14 Addressable Contact Input Devices
The PEGASYS Contact Monitor (P/N 70-407008-00X) allows
an installer the ability to interface typical NO/NC fire alarm de-
vices, such as water flow and tamper switches to the PEGAsys
system. The contact monitor is also used to interface to the
Manual Alarm, Manual Release and Abort Stations. The ad-
dressable contact monitor device is programmable to report in
the following manners: Alarm (default), Trouble, Manual Alarm,
Waterflow Alarm, Manual Release, Abort, Supervisory and Nor-
mal (Silent input). Its default setting is alarm when programmed
using the Autolearn function.
The unit includes a connection for an optional status LED which
allows the device to indicate its present operating status. In nor-
mal standby mode the LED will flash every 9 seconds, in trouble
condition the LED will be extinguished, when activated the LED
will flash every 2 seconds.
