operation and maintenance

the FS-400 strobes provide a lower current draw which allows for more devices on a NAC circuit while reducing the number of external power supplies required

These intelligent sensors utilize a state-of-the-art thermistor sensing circuit for fast response and are designed to provide open area protection with 50 foot spacing capability

In addition to back up amplifiers each SIGA amplifier has an on board 1kHz tone generator that can activate in the event of input failure or if no back up amplifier is available

Silent Knight SK-PTIR-W 23/12 Like the entire SpectrAlert AdvanceSK PTIR W Multi criteria detectors are addressable detectors incorporating PTIR detection principles. Advanced algorithms maximize the advantages of each sensor type creating a more robust detection strategy that rejects nuisance sources but still responds quickly to real fires. They are compatible with 5000 and 6000 Series addressable fire alarm control panels using SK protocol. Datasheet (Technical Specifications): Download SK PTIR W Datasheet (PDF)
