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-xxx 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 installations.

Please check individual panel listings for compatible

bases.

 

OPERATION

The SLR-24H photoelectric smoke detector utilizes two

bicolored LED's for indication of status. In a normal

standby condition the LED's flash Green every 3

seconds. When the detector senses that its sensitivity

has drifted outside the UL listed sensitivity window the

LED's will flash Red every 3 seconds. When the detector

senses smoke and goes into alarm the status LED's will

latch on Red.

The detector utilizes an infrared LED light source and

silicon photo diode receiving element in the smoke

chamber. In a normal standby condition, the receiving

element receives no light from the pulsing LED light

source. In the event of a fire, smoke enters the detector

smoke chamber and light is reflected from the smoke

particles to the receiving element. The light received is

converted into an electronic signal.

Signals are processed and compared to a reference level,

and when two consecutive signals exceeding the

reference level are received within a specified period of

time, the time delay circuit triggers the SCR switch to

activate the alarm signal. The status LED's light

continuously during the alarm period.
