Ionization Type Smoke Detector The SIH-24F has responsive, yet high operational stability for an extremely wide range of uses. The SIH-24F can be used in areas where early warning of trouble from super-heated or flaming combustibles is expected. The SIH-24F is also constructed to be effectively used where RF and other electrical interference is expected to be encountered.
HSB-224, HSB-224R or HSC-4R bases may be used with the SIH-24F. Current interchangeable devices are SLK-24F and SLK-24FH.
The SIH-24F includes a status LED which blinks approximately once each second, indicating the head is powered. The status LED lights continuously during the alarm period.
HSB-224 SMOKE DETECTOR BASE The HSB-224 Smoke Detector Base is designed for use with Silent Knight Smoke Detector Model SIH-24F The HSB-224 is a 6-inch polarized base with annunciator output featuring a current limiting resistor, transient protection, and a blocking diode to enhance annunciator function. The HSB-224 is available for applications not requiring current limiting.
HSB-224R AND HSC-4R SMOKE DETECTOR BASES The HSB-224R and HSC-4R Smoke Detector Bases are designed specifically for use with Silent Knight Smoke Detector Models SIH-24F, SLK-24F, SLK-24FH. Both are 6-inch bases with two Form C (DPDT) contacts (1 amp at 3OVDC and 0.5 amp at 125VAC) where relay contacts are required as a function. Underwriters Laboratories approved for releasing device service.
