The Model SS4 Optical Fire/Flame Detector is a quick response detector that incorporates Ultraviolet (UV), Wide band Infrared (IR), and Visible (VIS) spectral range sensors. The field of view is the widest in the industry with a 120 degree 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 with complete spectrum information, virtual immunity to false alarms from arc welding, corona discharge and other common UV sources is achieved. SS4 fire detectors are easy to install and simple to operate. Maintenance is also minimized due to the built-in self-testing feature and modular design.

The SS4 operates from standard 24 Volt DC power and interfaces to approved fire alarm panels or standard PLC’s. When power is applied, a 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 non-volatile memory for retrieval and evaluation. This FirePic™ data can be used to postulate the cause of the fire.
