llHGrFr-ril<r omerico corporolion StK-2 4FIn PHOTOELECTRIC/HEAT SMOI(E DEIECTOR APPLICATIONS The SLK-24FH can be used in all areas where Photoelectric Smoke Detectors are required. It is best suited for smoldering or flaming fires. The 135SFheat sensorcan initiatean alarm independently. The heat detector is UL listed for 50'spacing. HSB, HSC-4R,HSC-R,or YBA-NI sryle basesmay i'le used with the SLK-24FH.Currenr compatible devices are SLK-24F,SLK-24FL and SIH-24F.

In a normal standby condition, the receiving element receivesno light from the pulsing light source. In the event of a fire, smoke entersthe detectors and light is reflected frorn the smoke particles to the receiving element. The light received is converted into an electronic signal.Signalsare processed in the comparator, and when two consecutive signals exceeding the basic level are received within a specified period of time, the time delay circuit triggers the SCR 'fhe switch to activate the alarm signal. StatusLED lights continuously during the alarm period, if the alarm is activatedby smoke. Vhen the alarm is activatedby heat the Status LED will not light. The fixed tempera re heat element opemtes independentlyfrom the smoke sensingchamber, and causesan alarmat the control panel when the air temperature reachesapproximately 135SF,whether or not smoke is present.
