SS2-A & SS2-AN Multi-Spectrum
Digital Electro-Optical Fire Detector
Fire Sentry SS2-A and Fire Sentry SS2-AN
The Fire Sentry SS2-A, (latching Fire Alarm relay), and Fire Sentry SS2-AN
(nonmatching Fire Alarm relay), represent the world´s pre-eminent UV/IR
technology for Electro-Optical fire and flame detectors, with thousands
successfully operating in a multitude of installations worldwide. This
detector senses radiant energy in the Ultraviolet (UV), Visible and Wide Band
IR™ spectrum. The radiant energy from all types of flaming fires will alert
the detector to their presence.
The field-of-view is the widest in the industry with a 120° cone of vision.
This means each detector can cover more hazard area. Greater sensitivity also
increases the volume of coverage by the detector, up to four times more than
some other detectors.
Fire Sentry SS2-AM and Fire Sentry SS2-AML
The Fire Sentry SS2-AM, (latching Fire Alarm relay), and Fire Sentry SS2AML
(non-latching Fire Alarm relay), represent the world´s pre-eminent Ultra High
Speed UV/IR technology for Electro-Optical fire and flame detectors,
successfully operating in a multitude of installations worldwide. This
detector senses radiant energy in the Ultraviolet (UV), Visible and Wide Band
IRTM spectrum. The radiant energy from all types of flaming fires will alert
the detector to their presence.
The field-of-view is the widest in the industry with a 120° cone of vision. This means each detector can cover more hazardous area.
The field of view for the Fire Sentry SS4 detectors is the widest in the
industry with a 120° cone of vision. This means more hazard area can be
covered by each detector. Greater sensitivity also increases the volume
covered by each detector, up to four times more than some other detectors.
Using sophisticated microprocessor signal processing algorithms, false alarm
rejection is maximized with virtual immunity to false alarms from arc
welding, corona discharge and other common non-fire sources.
Operation
The SS2 operates from standard 24 Volt DC power and interfaces to approved
fire alarm panels or standard PLC’s. When power is applied, an internal self
test is performed and the fault relay resets to show no faults. The detector
is then in normal operation.
The front LEDs flash every ten seconds to indicate power is on. The continuous
spectral data stream of information from the sensor array is analyzed by the
microprocessor. On Alarm, the detector activates the alarm relay and stores
all of the pre-fire spectral data from the sensor array in nonvolatile memory
for retrieval and evaluation. This Fire Pic™ data can be used to postulate the
cause of the fire.
As part of the FS2000™ System, the the lens and complete optical path can be
checked using COP-i™ Test Sources in the system. Connection into the FS2000™
System is by the four wire RS-485 FireBus™.
