Detector
SIGA-PHS
Overview
The Signature Series Model SIGA-PHS Intelligent 3D Multisensor
Detector gathers analog information from each of its two fire sens-
ing elements (photoelectric and heat) and converts it into digital
signals. The detector’s on-board microprocessor measures and
analyzes these signals separately with respect to a third element
- Time. We call this technology 3D. It compares the information to
historical readings, time patterns, and several known fire charac-
teristics to make an alarm decision. Digital filters remove signal
patterns that are not typical of fires. Unwanted alarms are virtually
eliminated.

details.
Signature Series Overview
The microprocessor in each detector provides four additional
benefits - Self-diagnostics and History Log, Automatic Device
Mapping, and Fast, Stable Communication.
Self-diagnostics and History Log
- Each Signature Series
detector constantly runs self-checks to provide important mainte-
nance information. The results of the self-check are automatically
updated and permanently stored in the detector’s non-volatile
memory. This information is accessible for review any time at the
control panel, PC, or by using the SIGA-PRO Signature Program/
Service Tool.
Automatic Device Mapping
- The loop controller learns where
each device’s serial number address is installed relative to other
devices on the circuit. This mapping feature provides supervision
of each device’s installed location to prevent a detector from being
reinstalled (after cleaning etc.) in a different location from where it
was originally. The history log for the detector remains relevant and
intact regardless of its new location.
The Signature Series Data Entry Program also uses the mapping
feature. With interactive menus and graphic support, the wired cir-
cuits between each device can be examined. Layout or “as-built”
drawing information showing wire branches (T-taps), device types
and their address are stored on disk for printing hard copy. This
takes the mystery out of the installation. The preparation of as-built
drawings is fast and efficient.
