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 STANDARD FEATURES • Low profile, 2.2″ high (with base) • 2 or 4 wire base compatibility, relay bases available • 135°F latching heat sensor • Heat sensor protected by a built-in guard • Highly stable operation, RF/Transient protection • Low standby current – 45A at 24VDC • Two built-in power/sensitivity supervision/ • Non-directional smoke chamber • Vandal resistant security locking feature • Removable smoke labyrinth for cleaning or • Automatic Sensitivity window verification function meets outlined requirements in NFPA 72, Chapter Inspection, Testing and Maintenance. installations.
