Overview
Signature Series fixed temperature and rate-of-rise heat detec-
tors bring advanced sensing technology to a practical design
that increases efficiency, saves installation time, cuts costs, and
extends property protection capabilities. Continuous self-diagnos-
tics ensure reliability over the long-haul, while the latest thermister
technology makes these detectors ideal whereever dependable
heat detection is required. With their modular CO sensor, these
devices pull double-duty — continually monitoring the environ-
ment for heat from combustion, as well as its invisible yet deadly
companion, carbon monoxide.
Like all Signature Series detectors, these are intelligent device
that gather analog information from their heat and CO sensor (if
present), converting this data into digital signals. To make an alarm
decision, the detector's on-board microprocessor measures and
analyzes sensor readings and compares this information to histori-
cal data. Digital filters remove signal patterns that are not typical of
fires, thus virtually eliminating unwanted alarms.
The SIGA2-HCOS is a fixed temperature heat detector that
includes an advanced carbon monoxide sensor and daughter-
board. When the electrochemical cell reaches its end of life after
approximately six years, the detector signals a trouble condition
to the control panel. The sensor/daughterboard module is field-
replaceable.
