Fike - Photoelectric Smoke Detector Conventional [P.1.18.01-5]

PHOTOELECTRIC SMOKE DETECTOR

DESCRIPTION

The Photoelectric Smoke Detector P/N 63-1024, can be used in all areas where Photoelectric Smoke Detectors are required. The wide range smoke chamber makes the 63-1024 well suited for fires ranging from smoldering to flaming fires.

The 63-1028 is a non-listed version of the photoelectric smoke detector. The detector is identical to the 63-1024, except the 63-1028 does not have the magnetic test reed switch.

The 4” and 6” smoke detector bases and the 63-1012, two wire auxilliary relay base may be used with the 63-1024 and 63-1028.

OPERATION

The 63-1024 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 the UL listed sensitivity window the LEDs will flash Red every 3 seconds. When the detector senses smoke and goes into alarm the LEDs 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 LEDs light continuously during the alarm period.

63-1024 Sensitivity Test Feature
The 63-1024 Photoelectric Smoke Detector has a built-in automatic sensitivity test feature.
1. In normal condition, both LED’s flash green.
2. When the sensitivity drifts outside of its sensitivity limits, both LED’s flash red.
3. In the alarm state both LED’s are red continuously.
4. When the sensitivity drifts outside of its sensitivity limits and both LED’s flash red, the device needs to be cleaned or returned to the factory for cleaning. Refer to Hochiki Technical Bulletin HA-97 for cleaning information.
