APPLICATION
The PS-24H can be used in all areas where Photoelectric Smoke Detectors are required. The wide range smoke chamber makes the PS-24H well suited for fires ranging from smoldering to flaming fires.

SB Series bases may be used with the PS-24H. Current interchangeable / compatible devices are the IS-24 Ionization detector, PS-24 photoelectric detector.

OPERATION
The PS-24H photoelectric smoke detector utilizes two bicolored LEDs for indication of status. In a normal standby condition, the LEDs flash green every 3 seconds. When the detector senses that its sensitivity has drifted outside its UL listed sensitivity window, the LEDs will flash Red every 3 seconds. When the detector senses smoke and goes into alarm, the status LED will latch on Red.

The detector utilizes an infrared LED light source and silicon photo diode receiving element in the smoke chamber. During 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 executive signals exceeding the reference level are received within a specified period of time, the time delay circuit triggers the SCR switch and the LED's light continuously during the alarm period.
