Product Description

APPLICATION The SLR-24H can be used in all areas where Photoelectric Smoke Detectors are required. The wide range smoke chamber makes the SLR-24H well suited for fires ranging from smoldering to flaming fires. NS-4 Series, NS-6 Series, HSC-4R or HSC-R Style bases may be used with the SLR-24H. Current interchangeable/compatible devices are the SIJ-24 ionization detector, SLR-24V photoelectric detector and the DCD-135°/190° heat detectors. All NS conventional devices are mechanically compatible with Hochiki America HSB, HSC and YBA type bases which may have been used in previous
