TrueAlarm Smoke Detection
TrueAlarm Addressable Detection. IDNet addressable
device compatibility includes Simplex TrueAlarm
photoelectric smoke and temperature sensors. The 4008 fire
alarm control panel provides a subset of the complete
analog TrueAlarm features. TrueAlarm sensors appear to
the panel essentially as addressable detectors and that term
is used for 4008 documentation.
Approximately every four seconds the addressable smoke
detectors transmit an output value based on their smoke
chamber condition. The panel CPU internally maintains a
current value, peak value, and an average value for each
detector's output. Status is determined by comparing the
current value to its average value. Tracking this average
value as a continuously shifting reference point filters out
environmental factors that cause shifts in sensitivity.
Alarm Determination. Photoelectric detection sensitivity
is 2.5%/ft obscuration. All detectors can be selected for a
reduced sensitivity detection mode that satisfies the city of
Boston requirements. Addressable heat detectors provide a
fixed temperature alarm at 135° F (57° C) and may be
individually selected to also provide rate-of-rise alarm of
15° F (8.3° C) per minute where applicable.

Diagnostics and Default Device Type
Status Monitoring. 4008 TrueAlarm operation provides
the ability to automatically indicate when an addressable
detector is dirty or excessively dirty. The NFPA 72
(National Fire Alarm and Signaling Code) requirement for
a test of the sensitivity range of the detectors is fulfilled by
the TrueAlarm ability to maintain the sensitivity level of
each addressable detector.
Modular Addressable Detector/Base Combination.
Modular TrueAlarm addressable detectors use the same base
which allows different detector head types (photoelectric
smoke, or heat) to be easily interchanged to meet specific
application requirements. This feature also allows
intentional detector (sensor head) substitution during
building construction. When conditions are temporarily
dusty, instead of covering the smoke detectors (causing
them to be disabled), heat detector heads may be installed
without reprogramming the control panel. Although the
control panel will indicate an incorrect detector type, the
heat detector will operate at a default setting to provide heat
detection for building protection at that location.
